This is my first try at writing a software synthesizer.
It's a simple one oscillator, one filter monosynth. You know, like that very famous one.
It uses JACK for audio and ALSA for MIDI. There is no GUI but all parameters can be edited using midi messages.


The synth played through a LADSPA distortion plugin with a bit of delay and reverb to make it more intresting.

Needs JACK and ALSA to compile and run.

Updated to version 1.2. Emulates original TB-303 envelopes a bit better.
