Soundtank is a program that hosts musical instruments for
you to play; each instrument can be controlled via MIDI. You
can create custom instruments and save them to files, and
can also load instruments that other people create. It relies
on LADSA plugins, as it has no built-in sound synthesis
algorithms, but hosts them in "realtime objects" which
embody the structure of the audio signal flow. RTObjects can
be controlled in a completely customizable fashion using
MIDI events sent through the ALSA sequencer interface.
Soundtank outputs audio through ALSA or JACK.
