A couple notes:
I tried to provide additional input and output signals as befits the modular environment. On module B, each EG has output jacks, and the filter has a spare external mod CV input w/attenuator in addition to the usual 1V/Oct jack (with jack switchover from the pitch CV that can be provided from module A).
Module B has "MIXER B," which has four inputs, the external audio input with its own gain block and overload soft clipper for line level (or lower) signals, and three inputs for modular-sized signals, topping out at around 8V-pp.
Module A connects to module B with a short "module buss" 2x8 ribbon cable so gates and CVs are common to the module set, as well as the audio signal buss from the three oscillators and noise source. This means "MIXER A" found on module A mixes the oscs and noise signals into the common mixer buss alongside MIXER B when connected. Thus you have a 8-channel mixer: three onboard oscs, noise, external input and the three
8V-pp max. modular signal inputs. Module B has an "OSC BUSS enable" switch so you can disconnect the osc side if needed.
Module A has output jacks for each signal source that are under fader control. These same signals are always sent to the module buss header so as to not need to patch the outputs to the inputs--though if that is what you want to do, go for it.
Module A has two sample/hold circuits: one for the LFO S/H mode, and one for implementing a gated or floating glide action. a gated glide stops moving the moment all keys are released while the floating glide continues until it reaches the released key's actual voltage value.
Module A also has external CV input for pitch and mod "wheel" controls, and local controls to act as pitch and mod (though not as "table-saw wheels").
Finally, module A has the two PWM LFOs, one for OSC1 and one for OSC2. OSC3 has an LFOCV input jack. Due to the tight panel constraints of module A, the modulation output CV for modmix (LFO, noise mod) is in fact on module B, although LFO waveforms except for S/H clocking are also accessible from the OSC3 output jack.
All of this is of course on my single-board Crowminius too, I just did a logical split of the synthesizer into two modules, and did a second logical split between the host (panel control) boards and the actual voice circuit boards. I did not include a local MIDICV as in a modular setting you should have one already. I will have a 10HP 4-channel MIDICV module out after this however, designed to work with both crOwBX Euro and Crowminius Euro.
Cheers,
Crow
