[sdiy] best way to route cv in a non modular synth?

[Dan Snazelle]

but if the rotary is AT the destination (instead of Each source getting a rotary to tell it where to go) you can only have one CV per destination. the way i have it setup now, is if i want to have 5 cvs go to a vco and 3 to a vcf, i can do that. or i can have all 8 go to the vcf.

i am worried that having the rotarys at the input, i would have to have at least 2 per section. ( i like lots of modulation)

hmmmmm

thanks all

I have rotaries and radiobuttons on my synth too. I seriously dislike patchingcords. Also, it's much quicker to notate patches when you only need to notate the positions of rotaries.

You wrote:

each one HAS ONE MODULATON SOURCE (lfo 1 for instance)"

As an output may go to several places, while an input may only get one signal (in other words, you may not connect outputs to eachother) the rotaries should be placed on the inputs, and connect to several sources.


So: Each rotary goed to one input, and lets you choose from several sources.

Also, it's good to have a 0 volt position on the knob.

Lets say I have a set of 9 cv sources



and i have at least  8 destinations.



What is the least cluttered way to route these. NOT all destinations need all sources. THe only ones that might are the VCO and VCF.



the lag might only need 2 sources (envelope follower and frequency to voltage)

the sample and hold needs a few clock sources



the Vca needs a couple mod options



THe A/R gen might not need anything.



The Lfo Cv In needs a few too.



So that leaves what options?



the way I have been doing it is with 8 rotary pots

each one HAS ONE MODULATON SOURCE (lfo 1 for instance)



this can then be routed to any of the destinatons and whatever is left on the rotary can be for either ALL or combinations. (vcf plus VCO)



is this a good idea?



another way would be to have each mod source on a matrix of toggle switches.



any other ways?





i think its hard to keep A LOT of modulation options when you are working purely with pots... you start using up space quickly and it gets confusing to lay it out.



any advice appreciated!!!



thanks
