Any other CV pitch correction device like Theremini's?

Post by Joseph Merrill » Tue Mar 07, 2017 1:50 am

Hi all, first post

Moog Theremini has pitch correction allowing it to force your theremin playing onto a chosen key, with a percentage knob (0-100%). I chose instead the Moog Etherwave Plus for the two CV output so I don't have that feature. Is there a control device out there that can do what Theremini does to correct the pitch?

Thanks in advance!--Joseph

Hi Joseph,

Obviously, this trick won't help your control voltages, but this is what it
sounds like when you pitch correct the audio out of an Etherwave:

One easy way to get your Etherwave to control something else in a
chromatically-quantized way is to use a Pitch-to-MIDI converter (and then
ignore Pitch Bend messages).

Here's a cheap solution, but you can certainly find more feature-laden
Pitch-to-MIDI solutions as well:

If you have a modular system, a quantizer will do what you are looking for, there are many available, it takes a smooth voltage in and quantizes it to a chosen scale.
