WAV Trigger
Buy:
The first truly polyphonic embedded audio player.
The WAV Trigger represents an entirely unique class of embedded audio player. It inherits the best features of the MP3 Trigger and then goes way beyond.
Unlike most other embedded audio players, the WAV Trigger is polyphonic; it can play and blend up to 14 stereo tracks at a time. Each track can start, pause, resume and stop independently, and can have it's own volume setting, allowing you to create the perfect interactive mix of music, dialog and sound effects.
The WAV Trigger supports the MIDI protocol on its serial control port, enabling low-latency, 14-stereo voice polyphony for creating a basic musical instrument sampler. The latest firmware supports real-time playback rate control (sample-rate conversion) and MIDI Pitch Bend.
