Convert midi CC to CV internally?

Post by Mr D » Thu Aug 06, 2020 3:22 pm

Hi folks,

Does anyone know of a way to convert midi CC to CV internally in the computer, without doing a real-time bounce through an audio interface?

What i mean is, i have a midi track with some CC modulation on it, and i want to do something like "convert to CV" and i get an audio track containing CV signals that represent that controller, but in an audio waveform.

Any ideas?

Thanks! .......... Mr D

Doable. But I’m curious why you would want this, would you care to explain ?

Sure, i want to use the CCs that are modulating my music to also modulate 3D graphics in Blender, but Blender can't easily load in midi data, whereas it's easy to load in a wav file and convert the audio's contour into animation.

So i'd like a way to directly convert a CC curve into a WAV containing the CV!

See here! https://www.youtube.com/watch?v=l8RHRNZQEuE

Actually i realized i could route the CC to control the volume of a separate audio track. On that audio track i could place an audio file that is just a stream of samples all at 0dBFS. Then render this audio track and i have what i want.

But maybe there's an easier way?

make a max instrument > convert CC to audio > output audio

perhaps some rampsmooth~ or slide~
