Really nice, Kevin.
Now how about some samples?

Just finished building this for someone, it's a NAND synth but everything is separated and patchable with single header jumpers to extend the fun. There are also phototransistors linked to each pot and a four channel output simple mixer so you can have up to four thingies going crazy at the same time. I'll be sad trading this one away.
Cleanest build I've done yet:
Designed to be used while open for patching on the fly.

Nice idea! Any reason the pots are so tall though?

I thought it was time to build a keyboard for my modular, and being a bit of an ARP freak, I based it on the 3620 Keyboard with a few modifications.
The keyboard mechanics and midi PCB is from an M-Audio 49e, which feeds a Doepfer MCV4, but I'm only using CV and Gate at the moment.
The LFO, Delay, Kbd repeat, Transpose, Pitch Bend and Portamento were taken directly from the 3620 schematics (although the only copy I could find was very low resolution, and I could only guess at some of the component values).
I added a very basic version of Alain Coupel's PIC Sequencer, which is triggered from the LFO or keyboard gate, and also a switch to disconnect the LFO reset trigger.
Unfortunately, in my excitement to get the build done, I sent the wrong file to Front Panel Express... The correct file had a few extra graphics for slider levels and a few additional holes for the Doepfer CV2, 3 & 4 outputs - never mind, silly mistake that can be corrected later.
Just needs a coat of black paint inside the case to finish... bare MDF is not a good look

I was afraid to cut them down and ruin it. The knobs need the semicirclular cut shaft and it looked like an accident waiting to happen.
So now it's an artistic decision!

You're out of control, this is amazing. I'd love to hear more about the making of the cabinet/tolexing. I've started to build some simple cabinets that I'd eventually like to tolex, and could use some pointers.

I second this. The tolex is a nice touch.

Hi Eric, I started another cabinet just before you sent this message, but I'll take photos as I go along and try to get a simple guide together. I'll either post it here or put up a link to my site as soon as I can. _________________ Kronos 2-88, Kronos 61, Studiologic Sledge V2/SL, Broadwave ARP 2600EX, Broadwave 18U ARP based Eurorack Modular, Broadwave Minimoog Clone, GEM S2 Turbo.

Beautiful work AnalogCustom, and AndyR1960....
The DIY bar is being raised every time I look at this thread....

This is not exactly a synth, its an analogue computer.
patch it up properly and will sound like a synth tho
jumping the gun a bit with this one as it has not been wired up yet.
but everything else has been done, and i'm geekishly excited
more info - here!

not built any modules the last two month, but two racks.
another euro-modular, and a 19" Rack to replace the old studiorack

The board looks so simple for the amount of patch points there are on the panel.
I've always wondered how you could use an analog computer in a modular setup. Would you use it mostly as a CV generator/processor?
It would be cool to have a VU meter in there too. _________________ DRONEGOAT |

Consider me [fr]/[g]eekishly interested in any PCBs you might have for this project!!!!

Seconded. I was planning on building an analogue computer anyway - this would simplify matters a bit! _________________ glacialcommunications.com |

Well i thought I'd have samples by now but I can show you a previous example of this same circuit:
http://www.youtube.com/watch?v=Xq3rPsZG8ZY
It's four digital oscillators that modulate each other, based on the 4093 quad schmitt trigger NAND IC. There are also some phototransistors and momentary buttons that can be set up to muck around with each feedback loop.
Fun toy! _________________ ==================

Here's a sequencer panel I've been working on for a while.
There's a Klee in the center flanked by two Ryk 185 sequencers.
This thing is a blast!
