Looking for KB out advice

Post by TanSAT » Mon Jan 25, 2016 2:09 pm

So, I understand that the KB out patch point's range is -5v to +5v and that that is just the way it is.
The problem for me is that this negative voltage is making it impossible to for me to have the mother drive my monotribe.
Does anyone know what kind of circuit or module would "convert" the ±5v from the mother to 0-10v?
I just need to know the right term to be able to find what I'm looking for.
Thanks for your help!

You need a "signal processor" or "offset generator" that will add 5 volts to your -5/5 volt signal and make it 0/10 volt signal. They are available in several modular formats.

Actually, you could use the VC MIX on the Mother herself to do this. The knob is normalled to +5 volts when cranked fully clock-wise, so try this:

* patch KB OUT to MIX CTRL IN
* turn the VC MIX knob fully clok-wise
* patch the VC MIX OUT to your monotribe

That should do it!

Yeah, well, I didn't design it! All credit to Moog for making such a bitchin' noise maker :twisted:
