Modular Synth Panels

I just ordered a pcb for an SN 76477 module. Most of us have messed
around with these things for years. So Tom Henry tricked it out and
another fella came up with a pcb (run of 50) uses a cd4046 PLL.

I want to do it as a 2-3u voice panel.

Do I have any brethren ?

I'll try to get to this one, but it will be a little while.
What options do people want to see in it?

hey everyone - i have an snvoice on a a 4U panel using big switches and rotaries.

How do folks feel about adding a VC Resistor PCB for VC Filter Freq?
The caveat is my PCB only take positive CVs, and my bipolar PCB is a
little ways out still (debating whether to stick to vactrol or use a
13700...)

Dave, do you use the key input to noise control much? That controls the
pitch of the noise, or what?

Yes! For one of those plus the SN Supercontroller. MOTM, of course.

I also have 2 SN-Voice PCBs on the way from Bill, and intend to get
some sort of panel together in the MOTM format (ideally 2u as I'm
quickly running out of space), so, I'm with you on this one.

My feeling is that since this could be nearly a complete standalone voice if some sort of
filtering or wave animation was on board. In a modular synth that idea is pretty amazing.

If you need to knock out an extra hole or two in the panel in anticipation of a near future
upgrade, we'd be fine with that.

yo dave
i'm not quite cipherin' the mixer input trick. how do you sweep them w/
an lfo? i see three logic pins.

hey guys - sorry i've been out with an ear infection in my good ear! let me answer

you guys haven't been lucky! hopefully the bairn stays healthy.

i'd imagine we'd just have to condition the lfo(s) to the mixer logic
chips. pin 26 would be nice, and would give a mix of vco and noise.
would negative voltage hurt the SN chip? maybe, so we'd just have to
clamp the lfo's between ground and 2-3V.
and we'd have to cut traces...

maybe a 1u expansion panel is in order: VC Noise Filter, Gated Mixer
Control... hmmm...

I'm guessing the Mankato is engineered to go along with the SN voice very nicely as well.

yes, count me in!

im just about done soldering my SN voice and i would very much prefer
a bridechamber panel with all SN-documented options. im not
particularly down for any "add-ons"--i want to finish this thing
without the pressure of dealing with extras or modifying the pcb.

I'd like one also. Does anybody have any suggested layouts?

Hey Todd,

I like that layout -- nicely done. The only thing I'd add is the Noise "Keyboard" jack, since
we have room anyway.

I'll do the SN-Voice in the January panel run.

The current run has:
4-pot brackets
120R
320R
Doomsday
SubOsc
Tau Phaser (those went fast!)
DotCom Optic CV
DotCom Wave Mults


Cheers,
Scott
