Muff's Modules & More

are you actually scale voltages at the mod. index vca of cv out?
timbre circuit uses only positive voltage for regulation (fet based vca inside in the original scheme).
probably, your mod. index vca also controlled by positive voltages?
in that case you will have a 'hole' in control in half-period when the mod. osc. will go below zero

Okay, here's the latest version of the panel:

Changes:

- Name Change (longer name required a redesign of the masthead/attribution)
- Moved input jacks farther from the edges in order to (hopefully) allow for conversion to bananas
- Eliminated separate LIN & EXP FM inputs, in favor of a single switched input
- Distinguished output jacks with black, reverse type

I didn't check the PCB, but I want to make sure that the new FM input scheme is possible/useful. I love the additional clear space on the panel, but is there ever a case where you would want both EXP and LIN FM running at the same time? Would this require an impractical switch (like a 16PDT or something)?

I was really close to changing the word "modulation" to "mutation" everywhere on the panel...so we'd have a Primary Oscillator, a Mutation Oscillator, joined together by the Mutation Index in the center. I shied away because "mutation" isn't a standard synth term, but it sure is cool. Let me know what you think.

The panel looks great.

I think the lin/expo switch is ok
because you can still use an external attenuator for the 1v/Oct
if you really need simultaneous lin + expo FM.

The one thing that I can think of that it could possibly be benefit from is an external input for the Timbre section.
It could be normalized with a switching jack,
but it might be fun to try different waveforms as inputs,
or even different sound sources all together.
Then again, I am ignorant of this timbre circuit,
so I might be barking up the wrong tree.

Looking nice, I'm though a fan of dedicated lin and expo inputs with attenuators.

I'm with astro here too, I like having as many FM inputs with attenuators as possible. I prefer the separate Lin / exp inputs with dedicated attenuators.

I also agree that tapping an input for the timbre section would be cool.

panel is looking great!

"The customer is always right..."

Here it is with two FM inputs:

that's very beautiful!

two FM inputs is a good idea thumbs up

IMO those large black panels kinda make it look a little less refined than the CGS and CLee panels, but no biggie.

I like the new blacker version. Very easy to find the ins and outs.

How would one wire the pitch-> Fm mod?
My thought about the mutant index was to add one more switch to add FM to the lin FM input and/or the exp FM. Not sure how useful that would be but better to speak now than after the panels are done right wink

Also, I wonder if there sould be useful to have a external input to the timbre?
(I do have some wavefolders already and the MSU is even more, but it is probably a different character in the mutant timre version?)

It's not that I don't like the usability that the big black areas add, it's more that I think the way the section titles are done look really sharp and stylish in contrast. I'll be buying two regardless thumbs up

i like the black areas, although my ocd wants the Timbre box to be centered.

can't wait for this one!!!!

here's my input: I love the way it looks currently. Is PCB size dictating the HP of the panel? That center section could easily be condensed to have roughly the same density as the 2 oscs and possibly shave 4hp off the width. (addition of timber input could have an effect here too)

I think the pots should line up as much as possible. Not between the sections necessarily, but the small knobs in the OSC sections (aside from EXP FM att) should line up. I love the combinations of knob sizes and dont want it to be set up on a grid. This panel has personlity!

Black areas remind me a little of the TTA scheme (and thats not a bad thing, those modules look great).
