SO-404 v.1.2 by 50m30n3 2009-2011

SO-404 is a simple bass synthesizer using 1 oscillator and 1 filter. The oscillator is a simple saw wave oscillator and the filter is a simple resonant lowpass filter. You know, like that other very good and famous synth with a similar name. Just not as good and famous.

To run the synth you need Jack and ALSA. You can set a different midi channel by starting the program using the channel number as argument. The default channel is zero.

All synthesis parameters can be edited using MIDI CC messages.

Parameter list: CC#7 - Volume CC#65 - Portamento time CC#71 - Filter Resonance CC#72 - Release time CC#74 - Filter Cutoff CC#79 - Filter Envelope

If two notes are played together the pitch will slide according to the portamento time. Filter cutoff is influenced by the MIDI note velocity. A note velocity above 100 generates an accented note where the amp EG is replaced by the filter EG.

To compile the code you need the ALSA and Jack developement files.
