Muff's Modules & More

Of course, you can keep the big knobs! smile

Just meant that you might have to if adding other attenuators or inputs.

Here's what David said about a triple VCO/multiple VCOs from one PSU PCB in case anyone else is thinking about this:

Sneak peek for the wigglers:

Only "problem" was that I put a switch in upside-down. Fixed that in 30 seconds and otherwise it seems to work great!

dio - That sequencer looks great! With banana jacks and LEDs its like a rainbow in the dark.

I finally trimmed up my oscillator (sounds great!) and messed around with the linear FM mod some more. I no longer think that it is inverted but, I think it could use an amp at the input. It's a bit quirky but a fun timberal option as is. The exponential FM is great. Loving this oscillator, I need to build a second.

Diophantine
Your Sequencer looks great!
The combination of S-Trig outputs and banana jacks should prove very flexible!
I ordered a Sequencer PCB set from David last week.

Finally finished my first Synthasystem module (Noise Generator) today.
Getting some nice timbres by using the output to modulate the VCF Frequency on my SEM,
while varying the Level and sweeping between White and Pink noise.
The noise, at either extreme or any mix of White and Pink, sound quite pleasant and 'musical'.

Hope to have my Phaser, VCF, VCA and Triple EG completed in time for the Coventry Modular Meet this Saturday.
Everything is finished except the wiring and calibration (not looking forward to wiring the Triple EG! eek!

).

I think I've settled on the synthasystem I am going to build. I've already got 1VCO, both VCFs, VCA and EG built. I picked up a 6ux84 case and I think thats enough for a nice, compact system. I just ordered the rest of the PCBs. Here is what I'm looking at:
VCO A x2
VCA/Mix
VCF
Noise
Balanced Modulator
phase shifter
3xEG
Trigger generator
Sample & Hold
Voltage Follower
& CGS synthacon VCF

Thanks RSFC & Isaiah!

(Sorry, didn't see your comments 'til now.)

The full pics are up in my blog. I need to get busy with the Synthasystem again... have been beyond distracted with jury duty (lasting from Jan 27 to May 16th!), plus waiting on stupid things like rack screws.

I got my panels today! PCBs have been populated for some time. Now for some wiring & any troubleshooting then SlayerBadger!

Hello guys !

Been a while since my first posts on this topic.

Actually i finished 4 of the planned modules : Phase Shifter, 2x Volt Proc/Mixer & Dual Volt Follower.

All of the others PCB are almost finished to be populated and i'm waiting for some components regarding the build of 2xVCO, 2xVCF, 2xVCA & EG. Can't wait to starting up building the earth of the system.

A picture of my first attempt in building a cabinet:

And another one of the built modules :

And an another one : Input Amplifier. Had a bit of trouble with one of the SPDT switches but now, it works !! applause

looks nice mech

Just as soon as all my panels arrive from epinasty (custom copper! smile

) I'll have a lot to post-- all the modules, etc. Wat a great system. Thanks Nyle and David!

Just finished my 13rd module yesterday. applause

Next coming : 4x VCO, Sequencer & Env then 2x Trig Gen, another VCA/Mixer.

I'm working on the second cabinet right now.

I've decided to build all my unfinished and future Synthasystem modules with banana jacks.
The panels are natural aluminium with black knobs.
I plan to use red banana sockets for Gate inputs/outputs,
but can't decide on black or grey for audio & CV inputs/outputs.
Black might feel a little overwhelming along with the black knobs.
What do you think?

MechaSeb · Posted: Mon Nov 05, 2012 6:45 am Post subject:

i personally really dig the old banana schema color from the Synton 3000 modular. But with natural aluminium i'd probably go the same as Serge.

Isaiah · Posted: Mon Nov 05, 2012 11:24 am Post subject:

The Synton 3000 is black inputs and blue outputs, right?
Looks cool!

I'd like to keep red for gates (a la Serge).

The Serge standard is black for bipolar and blue for unipolar voltages.
I believe that the blue and black sockets are of much greater importance in Serge systems because some circuits only produce, or respond to, positive audio and CV signals.
Other than the Triple EG outputs (and gate signals), all the Synthasystem modules (if I remember correctly) are capable of producing and handling bipolar signals.
So, it seems to make sense, in the context of the Synthasystem, to only differentiate between audio/CV and gate signals in terms of colour.

So, black or grey?

I should add that it was by looking at Diophantine's system and then thinking for some time that I came to this conclusion. So, many thanks to him!

I had thought about different colours for CV/Audio and Gate inputs/outputs.
But, that would mean 4 different colours and a new standard to "learn" (not that it would bother me, just makes it easier for friends and bandmates. All the inputs/outputs on the Synthasystem are labelled as such, too).
