dssi 1.1.1 Audio plugin API for soft synths and effects

DSSI is a plugin API for software instruments with user interfaces, permitting them to be hosted in-process by audio applications. It is intended to be simple, GUI-toolkit-agnostic, and slightly biased towards familiarity with MIDI. The DSSI distribution package contains a JACK/ALSA-sequencer reference host and some plugins as well as the specification and header.
