-/**
-   @file sampler.c Sampler Plugin
-
-   A simple example of an LV2 sampler that dynamically loads a single sample
-   (based on incoming events) and triggers their playback (based on incoming
-   MIDI note events).
-
-   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
