A portable (SDL) audio synthesizer / tone generator allows users to draw oscillators and envelopes.
This is a very simple tone generator that allows users to draw an oscillator wave-shape and envelope, the oscillator can then be tuned by frequency and amplitude.
It can generate some interesting tones. It is interesting to see the contrast of limitations in comparison to a tone generator with frequency modulation and other forms of synthesis.
Make sure to follow the setup guide before installing
