Today my small discovery was...

[etckla]

Simple aha moment: had a pitch sequence going with various note lengths, but the sequencer doesn’t output gates/triggers when notes change. To get gates for each note change (that can be used to fire EGs and shape the voice into discrete notes), I needed a way to detect whether pitch CV is rising or falling, and then output a gate when that happens. Something like Ladik’s Derivator or CGS slope detector would probably be great for this, but I don’t have those.

I was able to derive gates for each pitch change using the two channels of Sport Modulator v2 (see the slope detection patch in the sm2 unofficial patch PDF) and a utility mixer. One copy of the pitch Cv to the top channel input, and inverted and offset copy to the bottom channel input. The END outputs are your gates.

I’m curious about other ways to patch this…how do you do it?

Cool! I just got SM2, looking forward to trying this out

For this kind of thing I use the gate out on the quantiser algo on my Disting MK1. Not perfect but does the trick!

Ah yes! using a quantizer that outputs gate/trigs on pitch change, smart

Have fun with the sm2!

Slew limiter and window comparator (and inverter if necessary). If the slewed pitch signal isn't near the "live" pitch signal, it has changed. Could also work with S&H and window comparator, with the comparator also triggering the S&H.

Or highpass filter the pitch signal to remove DC. Every steppy change in voltage will create a click which might be good enough to use as a trigger. Rings could also work for that since it auto triggers on pitch change.

I might use Teletype with the metronome set very fast and polling the CV input; there'd be latency and jitter that way but likely not enough to matter.

I’m curious about other ways to patch this…how do you do it?

Typical way to do this is a slew and comparator. Or anything with balanced-differential inputs, like a 902 VCA. Or an attenuverting mixer. Or one where one channel may be inverted relative to another.

minimally you can do it with a mixer and a capacitor patchcord. <--Need an inverter if the mixer is unipolar.

Slew -or the capacitor size- sets the sensitivity. And upper frequency limit.

When the input is unchanging both differential inputs see the same thing and since one is inverted they cancel and you get 'no' output. But since one signal is being slewed and the other is not, any change will cause the slewed signal to fall out of balance with the unslewed signal. The differential device you use picks this up and you have your 'somethings changed' output.

The scare quotes on 'no' output is why you need or want the comparator. Its hysteresis -which you can also patch as feedback into the mixer or VCA version- helps to stabilize the overall patch.

I've used this^ concept and the little bit of circuitry it requires often to derive triggers for VC SEQs and VC SWs.

If you read the CGS slope detector circuit description, you can see it's doing the same thing at its core. The added bells and whistles for detecting rising or falling change it some, but it's still differentially comparing a straight and delayed signal, and outputting when they are different.

Not exactly a new discovery but man, ring mod is great for metallic percussion

I had one out from 4ms Ensemble Osc doing a brightish pad.

Without thinking I took the other Ensemble osc out and fed it into a ringmod. Sine wave as the modulator, v/Oct into the sine, ring mod out to an enveloped VCA = Awesome crispy and modulate-able high end that just cuts through without being harsh.

Playing the modular with Korg’s Karma is amazing! I usually use my Kronos as a piano, but today I used Karma to drive my modular and it was incredible. The options are limitless and the real-time controls make it very playable. Why haven’t I tried this before?

You’ve had better luck than me. In my experience, Karma often overwhelms other devices with MIDI data. But it is awesome when it works.

Hmmm. I just gave this another go and it worked seamlessly. I had it running for about an hour with a lot of hands on messing with different Karma parameters and arpeggio styles and tempos etc. I’m using the Intellijel uMidi and StudioOne to set this up. Could it be an interface or DAW issue you’re having?

It could certainly be anything in the MIDI chain, not Karma itself. I just haven’t had the patience to troubleshoot. You’ve given me enough hope to try again.

Greetings,

The reverse is also possible!!! With a bit of gymnastics I got the KARMA clock advancing to a hybrid CV input. Was looking to clock sync my Juno6 with the KORG KARMA... posted a proof of concept on the KARMA-LAB forums.

Clocking like its 1981


Peace

I fell back in love with my Odyssey.

Wanted to add some space to specific parts of my drums but didn't wanna get all into the calculations with pams workouts and realized it was just as simple as running the triggers into a vca with a square lfo running into the cv. I've been playing with euro for a few years now and getting a part in a beat to take a break without creating a random mess has always really stumped me and I can't believe it was this simple.

Nice - I find it important to have a few good gate (as opposed to just trigger) sources, because you can use gates to open and close VCAs to make things stop and start.

That's one of the main ways I use my Doepfer 160-2. Put it in gate mode, mix some of the gates together, and you get some nice repeating, time synced but uneven gates for turning triggers and modulation on and off.

Other things to look at are crossfaders and switches (a bit like VCAs but you can use them to switch between eg busy and sparse clock) and Track and Hold, which "freezes" your voltage when you send it a gate, and let's it through untouched otherwise.

This kind of stuff is very important to me when patching. Rather than adding stuff, I'm trying to take stuff away, and VCAs (and similar) are the best take-awayers.

I've experimented with applying the same decay envelope to both drum triggers and a drone volume, for example. If you then add the same decay envelope again to the drum output, you get a nice rumble that fades out.

Oh hell yeah I don't know why an LFO was my first way of figuring this out but it's been a pretty nice and funky way to play around with spacing parts out randomly but still in a beat and changeable at the same time. Working with the older pams new workout plus pams pro workout and l for triggers and gates into a squid salmple for beaty things, so maybe I'll try to use the pro for the squid because of the easy visuals, and the new for some gates into the vca for things I want to control a little more easily than a lfo if I want that sorta sound.
Never thought of using a crossfader in that sense! Would shifting between a sparse and busy clock flow a little more smoothly that way??
And yes after a long time of playing around with a constant stream of sound, I wanna take it away for a bit and keep things moving along!

Not really, I just use them as slightly more flexible switches

I've cleared a significant amount of space finally...
Overall I'm in uncharted territory, as I'm trying work on not just capturing but using captures in a live way, so there's a lot of thinking/working out of the line of best for fit for me.
I've got two main ways for capture: full tracks via ES9 and hardware processors into Reaper laptop, as well as (I'm thinking) stems into Bitbox..

I can have a patch patched in for only so long before the magic is gone

I'd wanted to record a patch a while back but simultaneously ran out of all memory on my laptop, phone and email. Not getting email for about a month is, on the one hand, maximum liberation (in 2023) but at the same time so damn disconcerting and irresponsible.
So I've been deleting, tidying and moving files for a few weeks whilst I've had a massive patch of wires just collecting dust.

Mentally i decided to abandon what ever the mega patch was this eve. It is kinda cathartic, I guess... But yeah, my discovery is that I need to get stuff captured quickly else it makes my brain/spirit hurt.

Yeah I hear you on this. I can keep a smaller patch going for awhile, like a single voice—maybe two—that is doing something cool. But as soon as it gets 'complicated' the clock starts ticking…

Have you considered getting a cheap external HD to store stuff?

granular is the least interesting of all the clouds modes, at least for what i'm doing

[starthief]

Hmmm, when I had a Supercell I came to the conclusion that granular was the only mode I cared about. I liked using it for delays or psuedo-reverb more than the actual delay and reverb modes. And not having to remember multiple modes that didn't match the panel markings was liberating.

I don't know why it took me so long to getting around to patching this up but my discovery was using an envelope follower with a bass guitar to modulate an lfo, which modulates the CV of vca with the dry signal of the bass guitar. The modulation of the LFO this way is really fun. I'm trying to think if this is possible without something like a guitar. I can share a recording if there's any interest.

Alright! Here it is. I was patching in and out a couple other things along the way like a delay and a filter but you'll get the idea.

Yeah it's pretty neat stuff! The envelope follower creates a envelope based on the incoming signal, and it turns out that guitars make some interesting ones. Maybe someone else can chime in on the more scientific/mathematical reasoning?

I just used Maths as an envelope follower. I fed my TR-8S into it, then the sum output into my Make Noise DPO's Fold and it turned out really awesome.
Edit: Next, I'm going to use my SOMA Dvina next, instead of the TR-8S.

Yeah I was thinking about envelope followers a month or so ago and looked at a couple but then remembered the Maths manual had a patch for one. Such a versatile module and why it's so loved! Very cool stuff with the bass!!

I can patch with my body.

Try it: Plug a cable into an oscillator's output and leave the other end of the cable dangling. Plug another cable into a buffered multiple input (or I guess anything with a buffered input?) and leave the other end dangling too. Connect your buffered multiple output to your synth output so you can hear it. Now, touch the ends of the dangling cables with each of your hands. Your body transmits the oscillator signal.

This works without a buffered multiple, but depending on where you are sending the signal, it can lose a lot of voltage and become very quiet. So quiet it may not seem to work. It's pretty much inaudible if I try to go directly to my Befaco Out module unless I'm using a loud waveform like a pulse wave. Plugging into anything that can amplify the signal helps.

Can someone explain how the signal flows through the body with minimal distortion? It's kind of amazing.

I actually knew this was possible for a while because someone introduced me to Exploding Shed Touch Points. Today I realized that product does nothing special and you can just use regular cables. Neat! Electricity and electronics seem like magic sometimes (or maybe most of the time).
