How to split cv sequence in high and low outputs with triggers?

Hi! Nooby question here:

If i want to split a monophonic cv sequence in high and low outputs to be used with different vcos/vcas which tool do i need?
A comperator? Could my maths do this?

You mean distributing the v/oct between two vcos depending on the played notes? Tricky. I'd say you'll need a buffered mult in the first place because you will need to share the pitch cv among three different modules: the two vcos and one that will control the switching. Very likely things will not tune nicely when multing this passively. Then, I can think of different approaches that may get you there, my first idea is to use a voltage controlled switch, but to adjust the precise switching point I guess you may need an offset/attenuator thing like the pico scale or an attenuverter like cascade. Use the switch to distribute the gates opening individual vcas for the two vcos' outputs. Voila.

edit: when I typed this answer, the topic didn't say anything about triggers. Now I'm uncertain if I got that right or not
edit2: I can't comment about maths for that job, I don't have one. I know it can do a lot, but I never liked its interface and general layout.

Hi! Yea, i moved the topic and added the trigger issue as in this scenario the vcos would have independent vcas.
I also have the pico logic here which could help me split the triggers.

Seen this one?



It may be a bit overkill, and there are other ways of achieving it, but it might give you some ideas.
