Description:
Example of DSSI host
DSSI is an API for audio plugins, with particular application for software synthesis plugins with native user interfaces. . DSSI is an open specification developed for use in Linux audio applications, although it is portable to other platforms. It may be thought of as LADSPA-for-instruments, or something comparable to VSTi. . This package contains an example DSSI host which is useful for testing new plugins. It listens for MIDI events on an ALSA sequencer port, delivers them to DSSI synths and outputs the result via JACK. It does not currently support audio input (e.g. for DSSI effects plugins).
