Behringer 2600

[doombient.music]

I thought I might share an idea for creating random gate articulations .

I had some success using the lag processor on low frequency noise to get some random triggers. Play with the amount of slew, it's very touchy. Cool patch!

I had a go at combining Deans patch with Skweeegor's and this is what I come up with... damn thing started honking like a goose



I had to preamp the lagged noise to get it to a similar level as the oscillator pulses which I had to attenuate a bit but it was fun to mess around with!

I suppose I could have used KSS's tip for doubling the low trigger signal through the voltage processor but I hadn't read his post yet.

Howdy, and meh, fell down the stairs, eh?

Sliders are Bourns pal compatible, I need to check which size exactly, and yes, one led gone means several others in conjunction go blind too . Once it’s back in, they come on again!

Interrupted jack socket normal king could be related to external shock too. I don’t know the type but could desolder some from an old Neutron or so and send them, if need be. They’re not the nicest soldering experience but hey… alternatively, if mixed aesthetics don’t bother you, get some cliff 3,5mm sockets p, switched mono. They fit really well into the pcb holes., which are a tad larger than standard Eurorack.

Maffez, I think the Bourns part number for the broken slider would be PTL45-15W0-104A2, is that correct you reckon? The "W' indicates the color of the LED so if I could source white 2x3mm leds then I could replace it if e.g. only orange versions are available (as they seem to be at Mouser for example)). The one thing I am not sure of is the A2 at the end, this indicates the characteristic and this is marked as "audio" by Mouser... there is however also a PTL45-15O0-104A3... Any idea which would be the right one?

As for the other leds, as the contacts are still visible in the snapped-off lever, I touched them with a 3 mm red led - the other mixer slider led turned on but the vcf and initial gain ones did not. Weird, maybe the power consumption of the red LED messes with the other two?

As for the jack socket, I got a luminous idea (still have to do it though) - I will swap the socket with an "output" socket, e.g. the RM out, as the breaker contact isn't used there. That should be feasible I reckon. Did you say they are difficult to (de)solder?

These might work - sorry I don’t have a 2600 here atm and it’s been a while/never changed any four bourns parts. If 45 slider travel, then yep. Stupid me, dunno how a3 is different to A2 for the bourns. A2 i guess r get one each, just in case. And yes, separate leds an be used and using a different colour usually makes that one brighter/duller but I also remember them not lighting up (plus, check that you put ‘em in the right way round).fingers crossed!

The sockets are tough to desolder with an iron, at least for me. Single lose pins that are held together by the plastic housing - this principle makes them more resilient as for physical stress but they suck a lot of heat and you need to be careful when pulling them out. Can be done with patience though and if you have a desoldering gun, much easier.

I asked Rob Keeble. The sliders are indeed Bourns PTL compatible (although I don't know whether to use A2 or A3, A3 might be better as you say). He says the 2600 sockets (with the litle metal inset) are specially made for Behringer so cannot be obtained from other sources. Just wanted to confirm that.

I did a little video showing some things you can do with feedback on the 2600 but admittedly I don't really know whats going on when it comes to feedback. Maybe this helps someone though so I figured why not.

I used the B2600 for it's first live gig last week. It was for a benefit for Doctors without Borders in Minneapolis,MN,USA. Called Drone Not Drones, the idea is to maintain a continuous drone for 28 hours by successive overlapping 20 minute performances. There were over 60 acts there and a lot of great sounds. Ours was a duo, trombone and electronics plus myself with 2600, Microfreak, and midi guitar controller. I had spent the previous week working on different drone ideas trying to stay away from the more cliched drone sounds, can't say I succeeded there with the 2600. At home yes, but as an improvisation situation at the thing the Microfreak did most of the heavy lifting, the 2600 being not too light on its feet with me at the helm. But it was fun and a necessary experience to work under time constraints and collaboration. In order to do so in the future I need to get a patch that offers a limited but effective set of controls. The Microfreak offered a safety net via the patch memory presets I'd set up. Thought I'd share a photo 9f my rig using a suitcase as a case works well.

Something like a 16N faderbank can be used -by applying offsets and using 'stacked' sliders or pots to control output in relation to position for key parameters in a patch.

You can do this some with the 2600s Vproc section but it quickly gets used up. For example using a negative bias from Vproc5 into a VCO to give limit to one end of its coarse, fine or PW slider. Do this in several parts of a patch and 'patch memory' may be affected by simple end-to-end moves of sliders on the 2600 or the faderbank.

You can do this sometimes without using anything external to the module. For example *intentionally* tuning a VCO using coarse slider with the fine tune at the end of travel. Then moving it to some other 'start' or 'use' position, knoiwng you can get back to the initial state by shoving it full left or right. <--That's one way to get past ARPs lack of ease in returning oscs to starting pitch after a desire to 'bend' them.

Using a faderbak or stacked attenuators or mixers you can give 'meaning' to both ends of a slider or knob travel. The first in the stack sets range of the second. Use a third to apply an offset and you've got a preset.

Brilliant idea KSS..thanks. I will have to take some time to fully digest how I might be able to implement the concept.

[Bata]

I did a video showing how you can trigger the envelopes/sample and hold with an audio source

[Bata]

still, reverse mixing/"backwash" stuff is fun on the 2600 - another sweet one for getting strange sounds is to plug the left mixer channel output (carrying the vcf out) to ground (alligator clip between tip and sleeve of your cable will do) and pull that mixer channel almost fully up - makes the filter do fun timbres (at least on the behringer)

I was playing around with this in combination with feedback and I had all the lights going bright and dim in time with the feedback. Should I be concerned about this? My synth seems fine afterwards. I can try to recreate it and do a video if anyone is interested.

[KSS]

@Bata
No. You'tre intentionally modulating the 0V-GND. And since the LEDs are also using that reference they're moving with it.
As long as you keep the patching to the '2600' -not external gear- you should be fine.

Good to know thanks KSS!

I did not read the whole thread, but have to put my 2 cents in. I've had 3 or 4 arp 2600s before, and this behringer 2600 is f'n fantastic! I haven't been synthing in a while, so I bought it to teach my partner synthesis. What a great unit, a bit more "squiggly" than a real 2600, but just as good. In fact I think with some of the faster envelopes/etc, it sounds like a modded 2600.

[Bata]

I did a video showing how to manipulate the lights and it also shows a bit of what a shorting plug does to the waveform. I filmed this before reading KSS's post so I advise in the video that you don't try this but apparently it should be fine.

[Maffez]

Flicker mod for the win

[Bata]

Here's the patch that goes with the Shorting Tips video. I'm not sure if the shorting plug has much affect on the patch and the lights don't start pulsating but I was pretty happy with how this one came out.

[Neither]

Sounds great! Could you please give some more details about sending a CV sequence to the portamento footswitch in on the back? Do you use a S-trig cable and max. 3.3 volts or something like that?

Pretty sure I plugged a standard 1/4"TS cable into it and put the voltage to 5 volts for no glide and 0 volts for glide. I can mess around later today and let you know.

I did a quick video that I'll upload later today or tonight showing how it works but basically if you are using an 8 step sequence to the glide 5 volts will be no glide and 0 volts will be glide but the step you set to 0 volts won't glide the next step will glide. So you want the change between 0 to 5 volts to be on the step before the one you want to glide. I'm usually using this technique for random glides because if you want specific glides at specific times you can play it on the portamento button.

Many thanks for the further explanation and videos!

No problem! Glad it was helpful.

Indeed, that was lovely. You always give me hope!

[Bata]

Thanks but I realized recently my patches could have been better. What I'm usually doing is triggering the envelopes with either the lfo or the internal clock and mixing triggers to clock the sample and hold. I've found its much better to first mix 3-5 modulating squarewaves (this is where having an extra module or 2 comes in handy) in the voltage processor and then send the clocks to both the preamp and the S/H clock. Then from the preamp you send the mixed clocks to the envelope trigger in (the one that is normaled to the S/H clock). Then you can mix some feedback from the headphone out into the preamp with the clocks for more strangeness. It can be good to run the feedback through the ringmod first and send an lfo to the other input of the ringmod so the feedback isn't always present in the preamp.

[KSS]

Use the variable voltages -pos and neg- of the 3rd Vproc slider into AB of the E-SW to make your own pulse-SQ WF LFO-osc. Feed the E-SW out to the lag to get ramps.

Tie one or the other E-SW inputs to GND with an alligator or paper clip on one end of patchcord for more variey and interactive playability. Short tip and sleeve of one end 0V-GNDs whatever is plugged into the other end. <--Use a moog style V to S-trig patchcord to make this VC.

Usng both the 1st and 3rd Vproc sliders as DC sources increases the number of different results for this 5th osc, but costs you some use of the 4input mixer and its ability to add-subtract tonally relevant jumps fo the VCOs using the KBD.

The single biggest thing missing from a stock 2600 is not another EG or VCA, it's a comparator! <--Because it lets you do things to timing using saws and ramps and sines. Or lagged E-SW output when fed by Vproc DC Vs!

[Bata]

Comparator will probably be my first module whenever I decide to finally take the plunge. Either that or a quantizer. Or a wave folder.. or a LPG... or a multimode filter...or a loopable envelope with CV of the stages.. or..

Yes to all of that. I think a very versatile module would be the Pittsburgh Modular/Cre8audio West Pest for a budget solution? Although I don't think it has the loopable envelope or comparator. Their new Taiga seems to tick all the boxes, and then some. Personally I want to avoid the modular rabbit hole as much as possible. Been there. I want to stay as simple as possible and obviously even the B 2600 is pushing it in my case.

BTW not knowing what your intentions are for your patches, they sound interesting to me.

[Bata]

West Pest is a great idea I'll have to keep that in mind. Even if only the wavefolder gets used it would save me from getting a case and power supply.
