This is a simple synthesizer that uses Karplus-Strong string synthesis to model a piano.
It uses JACK for audio and ALSA for MIDI. There is no GUI but all parameters can be edited using midi messages.
Since every string is modeled separately it is quite heavy on the CPU. Also, it does no really sound like a piano.
More like a harp, maybe? Or a 80 string guitar?
Needs JACK and ALSA to compile and run.
Updated to version 1.2. Sounds better.

Jeremy Salwen did an LV2 port of my synthesizers.
