vco

3 Voice Quantized Digital VCO

The script is using the tone package to create 3 configurable digital square wave oscillators. Each oscillator can be quantized to a melodic scale and can set a root note for stacking chords or creating sub oscillators.

Getting Started

See the Getting Started first if you have not yet done so.

Configuration

Change up the scale and root note for each vco by editing the configure.go file. The list of available quantizer scales is here and the note references is here.

For example:

// Define the scale for each VCO.
scales = [3]Scale{
    Major,
    MajorTriad,
    Octave,
}

// Define the root note for each VCO.
roots = [3]tone.Note{
    tone.C2,
    tone.E2,
    tone.C1,
}

Building & Flashing

From the root directory of the project, use the tinygo flash command while Uncertainty USB is connected to compile and flash the script.

tinygo flash --target xiao-rp2040 ./vco
