-== Sampler ==
-
-This plugin loads a single sample from a .wav file and plays it back when a MIDI
-note on is received. Any sample on the system can be loaded via another event.
-A Gtk UI is included which does this, but the host can as well.
-
-This plugin illustrates:
-
-- UI <==> Plugin communication via events
-- Use of the worker extension for non-realtime tasks (sample loading)
-- Use of the log extension to print log messages via the host
-- Saving plugin state via the state extension
-- Dynamic plugin control via the same properties saved to state
