Teisco (or any other analog synth) filter cv control

MIDIfication

hi

I have a teisco 60f synth, it has external audio input and it can use any audio as an oscilator, my intencion is to use it with the midibox sid, all works fine because i can trigger the envelopes of the synth via gate pulses the problem is it doesent have a CV input to control de cutoff  :-[ , my question is:

how can I do that?

is there any “standard” way to control the value of the cutoff (or any other) pot with CV?

any info will be apreciated.

thx in advance

I have a Teisco 110f  :). It’s probably out of tune seeing as I haven’t touched it in a while. I remember the KB scaling wasn’t very good when I got it. I also have the schematics/ service manual.

You could probably wire to the filter cutoff knob, but you will need an AOUT_NG or _LC module to generate the CV.
