[linux-audio-dev] DSSI (Disposable Soft Synth Interface) 0.4

[Chris Cannam]

I'd like to announce a new version (numbered 0.4) of the DSSI synth 
plugin API proposal.

  http://dssi.sourceforge.net/

Disposable Soft Synth Interface (DSSI, pronounced "dizzy") is a 
proposal for a plugin API for software instruments (soft synths) with 
user interfaces, permitting them to be hosted in-process by audio 
applications.  DSSI 0.4 was constructed by Steve Harris, Chris Cannam, 
and Sean Bolton.

DSSI is intended to be simple, especially for plugins;
GUI-toolkit-agnostic; and slightly biased towards familiarity with
MIDI.  It's proposed as an interim measure until bigger and better
things come along: hence "disposable".

The 0.4 release addresses the problem of efficiently managing shared 
resources among instances of a plugin by providing explicit support 
for plugins that may be run in a group.  It also clarifies issues 
such as thread-safety and fixes a few other problems with the 0.1 API 
identified on LAD and elsewhere.  We think the 1.0 release could look 
pretty much the same as this 0.4 version, barring any more stupid 
mistakes.

The release contains the RFC, the dssi.h header file, example host and 
plugin code, and now the all-important FluidSynth wrapper plugin.

Comments to LAD please.
