Video - an unconventional way to use MIDI Guitar

please put me on the list, i think this will be a huge hit. unlike many of the other synth pedal solutions this one has balls (sorry, but that’s just the only real way to put it).

people will want this.

hello my fellow nerd friends..

i just finished writing a prototype for a pitch tracker that will be used in the pedal. its monophonic, but it rejects polyphony decently. the waveform shows the live guitar input on top (playing a low e) and a generated sine wave on the bottom based on the detected pitch. it feels quite fast :smiley:

just wanted to share this excitement with someone!

cheers :slight_smile:

it occurred to me that the extremely low latency probably accounts for at least half of the pleasure playing this type of guitar synth provides.

if so, this also bodes well for mg3 mods. over time i believe people will start to load the near zero latency presets long before they reach for the ‘fancy’ stuff.

Yes I think so too. I tried other „generic“ pitch trackers for generating the sine wave, and it feels quite different from using MG3 due to latency. But because I cannot put MG3 into a hardware pedal, I had to write my own tracker.. while MG3 uses a neural network which I don’t, I think it also does what I‘m doing: by looking at the phase relationship and harmonic spread of the overtones in the guitar signal, it’s possible to predict the fundamental frequency before it has completed a full cycle. That theoretically cuts down the latency to about 6ms for a low e, in comparison to other algorithms that take one or two full cycles (about 24ms). The result is a pretty snappy response.

So that screenshot actually shows the speed at which the engine spits out the note that is played :slight_smile:
