Hi everyone, we just published a much anticipated plugin to the store, the Audio to CV Pitch!
With original work by @BramGiesen and then me finalizing some details, with the usual MODGUI similar to the CV plugin collection.
For the most tech-curious ones, it uses the “yinfast” algorithm from aubio, together with fftw.
We tuned things in a way to have a good balance of latency vs pitch coverage.

The Audio To CV Pitch plugin is a tool that turns your audio signal into CV pitch and CV gate signals.
This allows audio from instruments (such as guitars) to play and control synth sounds and effects.
It detects the pitch in your incoming audio signal and outputs a 1V/Oct CV pitch signal on the top output.
The bottom output carries the CV gate signal, it sends out 10V while a pitch is detected, and resets to 0V when the pitch can no longer be detected.
The Sensitivity parameter can be increased to detect quieter signals, or decreased to reduce artifacts.
The Octave parameter allows you to shift the detected pitch up or down by a maximum of 4 octaves. When set to 0, it will output the same pitch as is detected on the input.
The plugin also features 3 parameters that are not visible on the plugin interface:
The Hold Pitch parameter sets whether the plugin resets its outputs to 0, or holds the last detected pitch.
Increase the Confidence Threshold to make sure the correct pitch is being output, or decrease it to get a faster response time.
The Tolerance parameter influences how quickly you can change pitch, turn it down for a more accurate pitch output, or turn it up to make it easier to jump from one pitch to the next.
As a CV noob, how do we implement this in a basic form? Can I just link this pedal to a midi synth/generator? I’m assuming no, and we have to use CV oscillators?
Hi! Congratulations! I love my Mod! You need to download it from the plugin store. Make sure you have “show beta plugins” enabled! You will also need other CV plugins to make sound. I used it with a CV poly synth pedalboard and feed the signal from the plugin into the chain i stead of the “midi to CV poly” plugin. It’s great fun! I was playing with it yesterday with a mic’ed handpand :-). Enjoy!
Luckily the Mod Forum is a great place to Iearn! I’m learning new things all the time. I believe the plugin is monophonic. Have fun! Remember you’ll need a “CV VCO” plugin and and a “CV gate” plugin to make it sound.
Yeah I was just trying to hook it up to an oscilator and another audio to cv to a vca to have the synth follow the envelope of the guitar but no sound yet. Maybe I should get a modular synth running on it’s own first and then plug in this thing…
Hi there, does anyone have a pedal board with this set up to share? New to using cv so a working example with the audio to cv pitch working would be great! thanks
I created 5 pedalboards for the MOD Dwarf that use the Audio to CV Pitch plugin to create some guitar-playable synthesizers. If you’d like to learn more, make sure to keep an eye out on MOD’s social channels, there are some videos coming up in the next days
