Monotron Synth

This is a very rudimentary synthesiser for use on Monotron.

It is #![no_std] crate with no dynamic memory allocation. It's a small structure containing four oscillators where each oscillator has a volume, a frequency and a waveform. You can either modify the oscillators, or pull out the next sample. Each sample is calculated as the sum of the output of each oscillator, and the samples are signed 8-bit values.

It produces a pretty gritty noise, which if you're trying to simulate a late 1970s / early 1980s home computer is probably about right.

Waveforms

• Sine wave
• Triangle wave
• Square wave
• Noise (ish)

TODO:

• ADSR envelopes
