Its a trigger input, that is capable of generating a clock signal after two or more "pings" and dividing it, or just using as a normal trigger. Easily done elsewhere. If you send the envelope shape into an adjustable linear/exponential vca etc, you can change the shape of the curve. Maybe not as much as the PEG does however. You could also mix two "pinged" envelopes/one shot lfos to create a new shape. Or wavefold it. Or send through a resonant filter or waveshaper/distortion/bitcrush etc.

Simple clock divider for polymetric experiments & fun outta CV Step Seq :drums:
Super-easy two-patchcord method of generating poly- and syncopating rhythms, breakbeats, and progressive/math rock-like odd meter time signatures.

1. Patch clock signal to a simple 8-step CV sequencer like Hexinverter Sympleseq. One that is required for this must have “reset” toggles on each step (physical switch that shortens the sequence as you activate it). KORG SQ-1 is another example of that, with its Active Step functionality.
2. Set CV on Step 1 to maximum. Patch CV out to any clock in (of another sequencer or event generator).
3. Flip the switch on Step 8 of your Sympleseq to bottom position (it is a three-pos switch with Gate On on top, Gate Off in the middle and Reset on bottom). Likewise, your CV step length is now 7, making for Time Signature if you clock multiply the CV out by X8. (Reset on Step 4 and mult by X4 for ¾ or, better yet, forget the maths and go with the feel! :boat:).
4. Play with switches in real time to generate fun drum rolls, trills, and syncopations. Another cool live performance application is patching the CV out straight to trigger in of a drum module. Then you can use steps other than 1 for triggering the sound, example given: _П__ instead of П___ – likewise you will move around your sound on a grid for sort of “shuffley” swung time-delayed feel or making it occur on downbeats instead of upbeats and vice versa. (E.g., with time signature like 6/8. П_ making downbeat, _П — upbeat).
5. Try other sequences like П_П__П__ and resetting on 6/7/8 for aperiodic multiplications and time signature shifts instead of normal plain divisions.
6. Record / multitrack your song, take a cam, film a puerta de entrada fox and make a gif. What I want you to end up with is something as good or better as this:

Image

BONUS. Formula for Time Signatures:

CV Step Length: 7 = 1/7; 6 = 1/6; 5 = 1/5; 4 = 1/4; 3 = 1/3 (initial clock is triplet); 2 = 1/2 (init is tuplet).

Then, multiply by whatever: e.g. 1/3 = 0.33 (or 0.(3), to be most precise), meaning ~1.32 when multiplied by 4. There you get your modular waltz time signature of ¾, since 1/1.32=0.75=three quarters.

Another example: we want us some 5/12. Set step length to 5 for 1/5 (or 5/1, which is the same) and then mult CV track out consecutively by 3 and 4 (or 2 and 6), meaning: cv-> clock mult module, and then x2 out of it to another clock mult, patching off its x6 as our final point.

Have fun with your life and always inspect mangos you buy for added freshness and vitamins.

Delayed Melodies~~
Whenever you find yourself in a situation of having far too many oscillators and far too few delays, think of this trick allowing you to create copies of a melodic riff and position then on a time grid echoing away rather happily.

Described most concisely – and in the briefest possible manner, – what your ordinary delay effect does is recording an audio fragment and then playing it back once, several times or infinitely (if it goes to 110% feedback, for example). And, indeed, on some of those modules or stompboxes you could see Feedback labeled as “Repeats” – precisely for this reason. When not set to infinite, copies of the sound will also be dropping down in volume with each following repeat, simulating a natural echo.

Here is a way to thicken your sounds in an interesting manner making them fade out with tad more echo and adding some more unison and pseudo-ensemble/chorusey vibe to a musical part. :ghost:

1. Take a Gate off your primary CV/Gate sequence driving the main oscillator and mult it to your Gate Delay of choice. If no single one is to be found, try patching in to an ADSR/ASR/AHDSR – or any other three- or more-stage envelope with Hold or Sustain – and then adjusting the Attack setting the Gate Delay time. Patch this envelope to a Gate In of another envelope to see if it is triggered by it without problems.
2. Mult your main CV track to the input of Track & Hold module. Trigger it by a delayed gate, carefully adjusting delay time so that it hits before the Step 2 of a sequence occurs. Likewise, you will get a copy of a sequence (example: _¯__) with the same shape and note relationships (intervals) but shifted in time like __¯_.
3. Patch the T&H out to V/Oct of a VCO2. Set it to be the same pitch and waveform as the original one (ideally it must be the same module by the same manufacturer) to make the most similar “copy” of a sound, or alter its timbre to taste for less delay-like and more orchestral unison textural type of sound to sculpt a dreamy ethereal pad you always wanted.
4. Trigger another envelope by the delayed gate and patch it to the VCA CV In with Oscillator 2 going to the VCA In. Patch the main (non-delayed) Gate to another envelope, and then that envelope (to ether with Oscillator 1) to a different VCA. Use the same envelope settings for both, but lower the volume of VCO2 a little to sound like echo. Mix two sounds.
5. Repeat steps 1-4 with Oscillator 3 (hopefully your T&H is double!). Delay the gate slightly more (but within step 1 overall duration). Lower the volume even some more and try shorter envelope like AR for this second repeat if you don't want too long and too whooshy tail (unlike foxes and coyotes, many people do not lust after a puffy & fuzzy tail, even if it makes for a decent balancing pole for tightrope dancers and funambulists! :lisa:)

Now, what makes this patch the greatest boon is the fact that it will work equally well with sounds of any duration: from extremely short to earth-spin-long and infinite. On some occasions – like, when you are setting for a very slow tempo and have extremely long sustained notes and note durations – you can skip the whole gate delay thing and be able to fade in copies of the sound via cranking up attacks and making those huge unison clouds of sound and heavenly pads. This still won't yield the same result (“repeat”-like quality due to different transients caused by longer attacks), but if all you want is richer and more spatial sound (more chorus and ensemble-like), this can quite hit the ballpark.

Another way of simplifying the patch routing in this case (and still getting very delay-like) is dropping down just T&Hs but not gate delays. Sure enough, you would not need to shift the CV sequence for a minute long drones, since you can safely fit several fade-ins and outs within a single note duration. However, the method described would work well even with zero attack percussive sounds and the like: by aiming for the short gate delay times you can try some slapback echo-like metallic percs or pseudo wows and flutters (patch some LFOs to auxillary oscillators for tape playback speed pseudo pitch shifts).

Bonus tip: by shortening each individual sound's release time, you can also try out various melodic coloration tricks like diminution / cambiata.

Melodic Embellishments Baroque Style: Grace Notes
Wikipedia: Grace note, Mordent (pralltriller)
All with a previous patch originally inspired by the idea of patching up ghost and grace notes, I eventually simplified it in heaps and found a simpler way. Originally I was looking at T&Hs as the way to retain note intervals but shift the sequence so as to achieve this call-and-response behavior with one note (a semitone or tone above/below) hitting up as the previous one has rung out or started, and then adjusting the second oscillator pitch to a semitone or tone higher, but then it became apparent you need no track and hold for that whatsoever:

1. Set the pitch of a VCO2 +1/2 semitones higher than the first one. Patch both to their respective VCAs controlled by their own EGs.
2. Gate delay the gate of your CV/Gate pair.
3. Trigger two envelopes with normal and inverted gate. Mix the VCA outputs.
4. Since you won't normally want this subtle ornamental compositional technique to occur all the time, patch up one of the gates to a VCA and control it with a separate gate track. Think of it as an Accent: every time you need an appoggiatura, enable that gate on a step.
5. If you look for more spontaneity, try patching that one gate to a sequential switch controlled by a random LFO or other signal or toss-the-coin module that will randomly let it through, adjusting the probability or random signal slew/rate for more or less grace notes.

Thank you too, and if anyone tries any of these out and records any audio fragments, music, or short vids, I'm keen on checkin' those out! I'll unveil some secrecy and announce one of the future patches is going to be supersaw via 3 VCOs with Hard Sync and 2 gate delays. (Maybe I should skip on this one as I just explained 99% there is to it in one third of a sentence. :spin: But I also have a sequential switch no-sync pseudo-wavefold ultrasaw that I will just go and patent now so that anyone patching it will pay glazed marshmellow royalties. :hammer:)

Important announcement: I also invented Thru-One, Thru-Two and Thru-Five FM that you can apply to any oscillator, even those without TZFM whatsoever (or make them TZ like with FM Aid).

Do not want to toot my own soprano sax too much, but I'm pretty proud to come up with this most revolutionary thru-five fm, I will even include patch tips on cv switching between thru-three and thru-nil fm to open up tone shaping possibilities even further.

PS: Real stuff that worms, not me sillyly flaffing around. (I think “sillyly” is the right adverb I'm in my own right to make up, and worms is a dope typo).

Vocoder Sounds without Vocoder

Transcending the oh-so-handcuffing “need gear to emulate some other gear”, I went on and explained how to downshift in the downshiftiest way possible and beatbox-replicate the co$ty 24-bandpass filter-involving devices:

Acoustic Voice Synthesis: Base Principles.

In that particular written piece I also illustrate the mechanics of singing and speech in synthnerd lingo, a lil' blend of a (semipseudo)scientific take on human anatomy explained in synthesist terminology. You'll find out where there are wavefolders in our bodies and how to use one's very own lips to low-pass filter the incoming (or, shall I say, outcoming?) audio. Tried to make this entertaining and would well be pleased to know someone reads this in its 996,517 page entirety!

Hahaha! Thank you bmot. :beer:

Here is an example of acoustic vocoder (3:06, song “Thieves”) - - > LINK. Music is by Alex not me in this one, and he did not let me use it, so I don't normally share it (or sell or post online anywhere), but for the sake of demonstration purpose I think this falls under Fair Use and he would not mind.

One-take vocals both in this (no overdubs, just three pinches of occasional pitch shifter in there like my other–EHX Crayon overdriven–track Squ33z1n [rough.]) and 404 and the rest of my “industrial Disney rap(s)” as I want to be honest about my abilities and keep it raw, gushing with life, and far-from-emasculated (see: “overproduction” and “talentless dolts” :lisa:).

In the meantime I aim to spit the whole fast Godzilla Part in one breath – 282 words in 30 sec, I think? This weekend got to 180 with 18.6 sec, so pushing towards this challenging goal in a way, I ain't MacLethal to speed-jabber for 77 seconds (!!), 30 would suit me fine. Must be noted, I've only found two people on YouTube up-to-the-task of it, so even thirty is hard enough of a task in context of this particularly fiddly verse of Slim Shady!

In other news (and I wrote about it in the linked thread but!..) I hit the F#5 yesterday (high note in Death/Judas Priest 'Painkiller'; a heart-rending screeching) which is another substantial achievement in my book, as temporarily overclocking cords to work 120% more efficient (640->780Hz, D#5 it used to be) is a small step for humble koala but a HUGE LEAP for the whole humanity.

Seriously, if you sing, you'll understand: going 1½ tones UP to the full-on mezzo note as a man is not so easy, especially given the fact that, for me, I need to do a glissando from A#4 all the way up to C5 and above and I can't hold B4 in sung phrases (not a sustained vowel) for more than 2 or 3 seconds. C5 is still tough [ :zombie: ], so that makes for a tonic to sixth flat, Bb->Gb, almost crossfit workout but for the larynx!! Bb (aka A#5) is my most comfortable high note I can settle on and do entire verses in falsetto. Up from there requires an effort, A#5 is almost child's play, very used to it after singing along to the Blood Brothers' Trash Flavored Trash repeatedly many years back in 2009.

If anyone has any tips on how to reach the A5 (see/hear: The Mars Volta - Cygnus Vismund Cygnus) or tips in general as far as making it easier on yourself with regard to extremely high notes, I am all ears. Ask me for a modular tip in return ;)

I'm having not too bad time of my life rn, as you can tell, all despite having been infected and recovering from this nasty crap of nineteen-something infection. I ride my old school rally Escort XR3 MKIII '82 (carburettor, 5-speed manual, close to 100 hp @ just 910 kg light unloaded state), sing random stuff and emulate vocoders.

There is also a project I'm involved with that will have two of my signaturely fanciful and beneficially handy patches on cardboard (!) so it's not entirely like I was slacking much since the last time this thread was updated. It just flew under the radar and remained unnoticed as more secret behind-the-curtains activity of mine and the guy behind it.

I'm in-and-out but in my heart always with you, not yet ponytailed (but maybe soon-to-be if you switch formats!) patchcord abusers, so shout out and hi to all of you. I'm sure bumping this thread is a good idea, more tips for everyone and dozens of sound-cooking recipes.

This is exactly where I want to be in a few years time. I have 21U of mostly a lot of basic Doepfer modules which were cheap, and I bought with the intention that if I get enough basic building block modules then I should be able to recreate a lot of the more expensive modules by combining them in different ways, with enough understanding of modular synthesis.

The problem is that I don't fully have 'the knowledge' yet and so these types of breakdowns are very useful. Any advice on how you can arrive at the state where you know this 'knowledge' is helpful too.

Thanks guys and welcome to the forums, logan mkii! :)

@wordswords I suggest reading some of the following: Buchla Music Easel manual; Madrona Labs Aalto (and in the meantime his other products, why not!) manual; Doepfer manuals (a must, especially for those functions that seem hardest-to-understand: logic, flip-flops, mixiplexers etc.); make noise 0-coast (and their newer synth) manual; make noise shared system manual & other systems' manuals. Check also as much of theirs as you can, especially more complex modules like Mimeophon, Erbe-Verb, Morphagene, their stereo filter etc for the insight on how these operate and what they are comprised of. Even for simple(r) functions like LPGs or something they have some very valuable patch tips, as well as on their YouTube Channel where they started tutorial series quite a while ago, but for the most time they are active, there was nothing like this, so get most out of it before an asteroids kills the dinosaurs and us!

Manuals are your friend, as you can tell, so check them out. Especially helpful with some of the more esoteric or hard-to-grasp modules and synths: oughta increase your tech-knowledge tenfold. I also suggest some good books on electronics (choose one by online reviews, or just surf the free resources). To really understand what's going on and come up with creative patches like I do you have to A) have good basics in EE; B) understand the signal flow of a function you want to recreate.

Unfortunately most of the modular documentation is hardly very good, and overwhelming majority of official pdf's doesn't even have signal path diagrams, which is the very first (and for those more experienced – close to the only one that is necessary) step to really comprehend and grasp what's going on and how to achieve the same results with separate building blocks. Instead some manufacturers obfuscate the simple things for marketing (you guys!! :foul:) or mere fun, and make up obscure and esoteric module names or panel labelling for something as simple as a diode array or a bunch of comparators.
:moneyburn: :moneyburn: :moneyburn:
To give an example, one of the patches in here was inspired by finding out how the SSF URA Analog operated. Sometimes you have to look up these things or ask somewhere in a thread ( :help: ), if manuals are too short 'n (or) vague.

Also, there was some decent breakdown of subtractive synthesis and wave types in the microbrute manual: nothing to write to martians about, bun can be good to refresh your knowledge. Certainly not Allen Strange book (one of the more valuable resources, but hard to find – at least used to; maybe now there's a reprint or easily attainable e-book), but still was good to see manufacturer provide few pages of nominal education instead of just “X knob does Y, good bye and merry christmas and have some good halloween-themed party at your thanksgiving”. :champagne:

There is a stickie in modular synth general discussion that, I think, lists key literature on the matter. And here (eurorack forums), too – some good stickie threads, too.

Personally, I do not think there has been written much useful synthesis study guides after the 1970s, which is appalling in a way, as it's a completely different time now, and ideally revised versions of those would have to take into account some of the more recent and current developments, trends, genres, and non-existing before things like bedroom music production and footwork drum patterns and talking synth basses and abandoned loft-demolishing stompy kick programming. This is sort of why I started doing things like this thread, it's more of “modular synthesis in 2021” (that we deserve :lol:) than something that, fundamentally and essentially, leaves you in the seventies (still wanna program a tenor sax on minimoog?) or, worse yet, stone age.

Oh and BTW!!! Just remembered probably the best–or close to–resource that can really up your synthesism. Speaking of programming strings and flutes and other cheesy and meaningless bland recreations of physically existing Instruments on one-oscillator monosynths... Some sound design articles on Sound on Sound website are incredibly good. This is the place I'd spend quite some months on, if I was wishing to learn more about programming techniques (this far I'm happy with my dark ignorance and mistake LFOs for phase-inverting comb filters and mults for complex thru-zero dual oscillators... :D).

Sure enough, if nothing in the world answers your question of “achieving X with Y” sufficiently and satisfactorily, you can always shoot a Q in this twig on a muff wiggler tree (metaphor for this thread) and I'll jump in with some A or A's (spelled: “ace”), so never hesitate!

Wait, what is this? :hmm:
To be honest, I may shelve this for now, as I was contemplating turning tips from this thread into some kind of a physically touchable product (like a book, but probably something more interesting; +digital brochure as an option), so this particular patch may be the most ostentatiously attention-grabbing to sort of advertise this, as it's hands down most killer one so far (and working).

As some kind of comfort and reassurance, I will share the secondary component to it without unveiling the underlying “FM->TZFM on any oscillator” technique:

Turning your Thru-Zero modulating signal into a Thru-One to Thru-11½ 8-)

To start this off, do not let the caption fool you: there is no such thing as a “thru-zero modulation signal”, there is just a signal. The point at which it becomes TZ frequency modulator is AFTER you send it to a dedicated (labelled or not but specced as TZ) CV input. I only used this for a lack of better phrasing.

So, what is this all about? With TZFM, as you know, the wave gets inverted at zero. As such, inversion always happens at 0V, and with perfectly symmetric (horizontally, rather than vertically; so the 0 for sine wave of static frequency always occurs like XoooXooo in the drum machine or metronome) waves it is slightly too predictable of a response. Even with more complex waves like toothy wavetables, it's gonna work the same if they have this kind of visual ripple just at the top (for the added harmonics) and not throughout the whole amplitude of a wave like wavefolded signal.

Let me explain.

The wave pictured is what would be square but with some triangley harmonics on top (what I called ripple, but better called: SCRIBBLE :lol: how do you like this, for a rhyme??)

Sent to TZFM input, inversion will only happen once: before _ & after П (17th letter of Russian alphabet, reads like “p” in “parrot”, spelled before “rrot” – now you are at 1/33 of your Russian letter recognition ;)).

On the other hand, if 0V point was not at the bottom but the top of “П”, tzfm circuitry would react to reaching it (the reference point of zero volts) SIX TIMES ALREADY making the resulting carrier oscillator wave more harmonically rich, resulting in richer sound thanks to this audio rate wave state modulation (six times faster than with the initial wave, no matter audio or LFO rate!).

The trick behind this is super simple.

Imagine the wave given as an example has max voltage of +7.7V and minimum of -7.7V, making it a 15.4V peak-to-peak. Throw it into an offset module and offset down one volt for some Thru-One fm action.

Inside the TZFM VCO it is still, of course, thru-zero, but these technicalities are beyond our interest. What interests us most is the fact that, by experimenting with different offset point, we can (and will, when using non-symmetric signals at the input!) make the resulting wave SOUND DIFFERENT – which, at the end of the day, is all that matters for us as musicians, score composers and the jolly fun-havers among us!

Up next, if you are interested to enter the Thru-Two or Thru-Four (or, God Forbid, Thru-6.66!) territories, just offset 2/4/ or six six six volta and be good.

In the case of our example, to really hear the difference, we need to offset (as you may have guessed) -7.77V to position topmost part of the “П” around 0V. With the wave of 15.4V amplitude (with possible headroom of Eurorack at around 24V, determined by PSU, summing largest numbers of respective +12V and -12V busses), offsetting it as much as minus seven point seven will asymmetrically clip it by approximately 3.4V (lowest point being -7.7 before to offsetting, and -15.4 after. bottom part will simply be clipped).

As such, you can not only shift the thru-x point at which the wave is inverted with offset, but also simultaneously experiment with pushing it into the positive or negative clipping zones to entirely change the “looks” and action of the modulator!

Of course, mixing the modulator not with DC (aka static or offset voltage) but with LFOs, EGs etc will make your Thru–X CV'able, opening up even broader territories of sonic fun and exploration! :headbang:

PS. I reserve the full rights to be the only eligible inventor of THRU-ELEVEN POINT FIVE fm synthesizer technique and have dobermanns as lawyers. Dontcha steal my shit, a process of hard brain work and fingertyping :spin:

Wow, thanks for this! I spent the whole summer moving, my studio dismantled, and seemed to have missed all the cool stuff 🙀

You missed me buy a car? Whoop. How sad!

Discovered a purple USB stick with hundreds of blissful synth ambient tracks lying around (Multidim.net) and had an especially nice ride today. I have a modern pioneer radio with aux & usb, way nice listening to stuff in quadrophonic (technically stereo but you get me) and not have to reach out for cable to insert in an iPod. You just start the engine, and vibrations fill the salon – very convenient! :party: So cool of Ryan (Entrancer) sending me this as a gift and that DYAD - CYBERIA tape (one of the absolute faves in my whole collection). To be honest, I used to sceptical about the format like, what, USB sticks? – but now, having a speaker-equipped vehicle, the obvious handiness is apparent: you can just swap those like tapes or CDs, plus there's way more playing time. :drinking:

Why I emphasize the convenience so much is 'cause my office is just one mile away, and I could buy an aux to bluetooth adapter for $5 and play whatever from my phone, but... follow me... a) reach out to the pocket; b) take out the phone; c) unlock it; d) open an app or whatever; e) look up an artist / album / playlist; f) press “play”; g) lock the phone and hide it. :zombie: One minute of action for a 5-min ride, and especially after having buckled up, squeezin' it into jeans somehow is extra challenge, nevermind having to get the jacket or coat out of the way first!!

Image

PS. I didn't spend my whole summer moving, 'cause I couldn't pass my fucking driving exam and spent about $150 extra bucks better be spent elsewhere. Hit the neighbours' car the same day I got the license, too, and almost had it confiscated for three months (but kept it asking punishment-deciding officer to charge me some more $$ instead. after him having added $120, paid nearly $250 to the government I hate last friday). You mentioned your studio, dcramer, but in my case it's my wallet that is dismantled!! :nuke: :rip:

PS². No regrets, though.
Whatever.
Fuck it. :mrgreen:

(Cycling) Envelope with ReTrig Off a VCO
More often than not, retriggerable ADSRs are a luxury, due to additional circuitry or not enough space on a panel if it's a slimline 4hp one designed to be compact. If, however, you are using yours for short percussive sounds and feel like trading it in for an uber-EG with CV over everything but do not really need all other fancy features apart of retrig it has, I've got great news for you: there is a way to get those drum fills and off-the-grid sync options without screwing new acqusition in – and even settling for one or unscrewing older one. All you need is a VCO with Hard Sync and readiness to follow rules (autonomous free-thinking rebels stop reading this IMMEDIATELY! :woah:)

Instructional patch tips to venerate and worship:

1. Patch a gate sequencer output to VCO hard sync for tempo-synced triggering of the contour. It will both trig and retrig (if needed) the envelope. For true retrig action (with separate gate, like 2 channels trig/retrig on ADSR) use a gate-to-trigger converter and OR combine with another gate in a logic module.
2. Take a Saw Output for short and snappy sounds, Ramp Output for whooshy noises or pseudo reverse playbacks. Wavetable Output for bizarre transients when you have special obligations (like deliver $10mil-sounding gulps for AAA budget Hollywood movies about gnome cyborgs saving the world :tu: ). Patch it to a VCA1 in.
3. Mult a gate output to VCA1 CV. Offset the Output into the positive range so that it starts at zero volts like normal envelope. VCA1 out will be your volume envelope (or kind of a different modulator, too, of course, if you want it to!).
4. Adjust the VCO Freq so that to have an envelope that we make complete a cycle within gate duration. For this, simply patch VCA1 out to VCA2 CV In with arbitrary audio in (oscillator wave or Trump inauguration speech) and preview the VCA2 out using your ears or oscilloscope.
5. The coolest bit: now we are going to make our envelope CV cycleable like some prohibitively expensive AHDSR module costing a kidney gemstone and (!) musically meaningful in terms of Tempo sync, too. For this we will patch another gate sequencer track to v/oct of a VCO, previously attenuating it to taste. Likewise, we will be able to have both one shot operation and also some cool trills/drum rolls/sound repeats when a need for those arises by arming up the secondary gate track. To have perfect Tempo Sync, make sure that voltage coming in is precisely 1/2/3 V etc, for this you might want to utilize a CV sequencer with OLED (or other kind of) display and program it to output root notes of different octaves (if its root is C1 @0V, then C2/C4/C5 etc). Patch this voltage to VCA3 in and control the CV In with Gate2. Or – if you are content with 5x note repeat – patch the 5v gate straight to v/oct and forget the preceding step.
6. By completing the previous step, we did equip our wannabe envelope-on-a-budget with CYCLE STATE TOGGLING CV feature that, however, acts in momentary (gate on = cycle on within gate duration) and not latching (gate on = switch cycle state 'til next gate) fashion. To add some additional superpowers to it, we can change the CYCLE CV response to latching by using a 2In-1Out sequential switch (controlled e.g. by Gate 2 or manual gate) and patching offset/sequencer voltage to one of the channels. Then, next, for the sheer fun of it, we can also use up the whole four channels of it with sending e.g. 2V, 3V, and 8V, and making tuplets/triplets/trills, optionally controlling the sequential switching with S&H for randomizing the rhythmic phrase.
7. Experiment with Gate Width on primary sequencer track triggering the envelope to cram more note repeats within its duration. Or – if you don't have such a parameter on one of yours – feel free to use this gate on CV In of a VCA4 with PWM SQR wave of auxiliary oscillator fed into the input. Adjust its pitch to fit the П portion of П_I within gate duration and mult it to its hard sync for on-beat (Tempo synchronized) triggering OR use hard sync not for drunk musician wonky swing effect. Adjust the PW with a sequencer, s&h, or manually.
8. If the idea of this patch sounds way suggestive of going out and playing live, you can patch a DC offset to the VCO v/oct instead of a sequencer suggested in Step 5, and note repeat with index finger and a thumb for nights long. 8-)

I HOPE THIS IS HELPFUL!

I too, recently discovered the convenience of USB sticks in the auto. So hassle free.
Thanks for including that Multidim link. Nice to get a feel for the Denver musical mindset, out there where they don't have the weight of excess air pressure holding them down.

Great thread; awesome tips! :yay:
