Grit VCO is a DIGENERATOR firmware that comes flashed when you first get the module. It is a VCO, somewhat similar in sound to early wavetable oscillators and the WAV synthesizer in the LSDJ gameboy tracker.

The FREQUENCY knob sets the oscillator's pitch, and all the related controls work like you would expect them to for a common VCO. OPT A enables the VCO output, and could be used as a basic "on-gate VCA".

The firmware has 8 waveshapes to select from, and 2 gritty audio effects to apply on them. Both the waveshape selection and the effect control is done with the CHARACTER knob and its associated CV input. Waveshapes start from sine on full CCW, through triangle, square, and to saw on full CW. One of the two loaded effects is selected with OPT B.

A gate on GATE 1 resets the waveshape on a gate and can nicely sync the module to other VCOs. GATE 2 locks the selected waveshape - the CHARACTER knob won't affect the waveshpe while the gate is high. GATE 3 locks the selected effect parameter, similarly to GATE 2 and the waveshape. Finally, a gate to GATE 4 will make all the stored waveshapes mutate, randomly interact with each other, producing new timbres.

Below is a set of parameters that you can customize for your Grit VCO. If you want to try out the stock variant, just hit GENERATE without touching any parameters. Have fun!

The CHARACTER knob scrolls both through the 8 waveshapes and through the 256 FX parameter values. Setting it to "Exhaustive" will make it skim through all 256 possible states (in increments of 8) for each waveform. In "Natural" mode, it will go from minimum to maximum over the entire range of the CHARACTER knob, in increments of 1, acting more natural and having more states. This, however, locks a separate set of values for each waveform. Use the wave and effect lock gate inputs, if needed!





The GATE output can serve different purposes. In "Spike" mode, it will output a very narrow pulse at the start of each waveform cycle, that could be used as a sync signal for other analog or digital VCOs. In "Square" mode, it generates a squarewave of the same frequency as the main output. The "Sub" mode makes GATE output a suboscillator squarewave an octavel lower than the main output.
