Okay, so I asked the question in the comments on midisizer.com and he said that an attenuated linear FM input would work well with the pitch bend CV. I want to have multiple linear FM inputs. Can I ju ...

Hello! I'm going to use the Midi2CV module by MidiSizer for my synth project https://midisizer.com/midi2cv-mk2/ but the 1V/Oct note CV and pitch bend are separated. What's the best way to mix these si ...

Can I just get rid off both the resistors and the jacks/pots without affecting the behaviour of the other controls?
yep, you could leave those out. Personally I would keep both as it is very useful t ...

I think the fine tune is usefull to tune it when it self-oscillates so you can use it as a 1V/Oct VCO.
So yeah, for general use you probably won't need it.

From "The filter is controlled via ...

I have no experience with this design so I don't know about drive but the cutoff frequeny
can be controlled with the two inputs (1V/oct, Envelope) and the Coarse and Fine controls.

Oh, that explai ...

I think for what you need this might be the best solution but it depends a bit on the maximum current. The main problem
will be heat dissipation. If you use another wallwart circuit for 12V there is ...

the 1uF filters the lower frequencies, and usualy have a somewhat higher inductance while the 100nF takes care of filtering the higher frequencies

Oh, I actually didn't know it made a difference co ...

I’d use a 1uF parallel with a 100nF

Hmm.. Interesting! Any specific reason for that?

the right voltage regulator should be a LM7805

Oh yeah, you're right. I forgot to change it.

Apart from that, do you think the circuit will work? Any ideas what the value of the middle capacitor ...

Ok so I researched it a little bit more (which I definitely should have done earlier. Sorry.) I made a schematic that I think would work.

Hello! Is the "Attenuate" knob in combination with VCO-1 able to provide a sufficient amount of drive for the filter or is there an easy way to add a drive pot to get more energy out of the ...

Hello!

I'm building an analog synthesizer (not modular) and I need a bipolar 15v supply for most of my modules (VCO, VCF etc), but I also need a 12v output for some of Ray Wilson's designs. What w ...
