Today assembling a Dual AD/AR
and also put my power in the case, with switch and the diy bus board.
I prefer to finish my panel and assembling module (only 4) before testing all, but just testing my Twin Drummer quickly
I installed it with the others drum modules in my 2nd case (instead of an cem VCO which will go into the new one)
all work fine, i’m very happy because the circuit was not easy to build
here a short demo triggered by the Big Button

Finished up one of 2 CGS66 - this one is running half-wave rectification just to get by until I find proper 18-0-18 center tapped transformers. (If anyone has a link for one that doesn’t have 22 dollar shipping, that’d be nice)
Trimmed for a perfect ±15v

the sound of the twin drum is so great ! this is from the design of LMNC with the cd4011? what modification have you make to add decay controls ? (I don’t remember that it was on the schematic, or I’m wrong ?)

@Dud, may I ask, why do you use a switch on your mults, rather than normalizing the input jacks?
you mean use the switch of the jack ?
yes, if you only plug in 1 input the others get the same signal.
I do that by reflex I think (I’ve always done them that way), but actually that would be better, more possibilities
I could still do it, but … to be continued
