Tsunami Super WAV Trigger (Qwiic)

Tsunami Super WAV Trigger (Qwiic)

The Tsunami Super WAV Trigger is a polyphonic audio player built around an ARM Cortex M7, capable of mixing up to 32 mono or 18 stereo simultaneous uncompressed 44.1 kHz, 16-bit WAV tracks. Each track can be independently started, paused, resumed, looped, and stopped with its own volume setting — ideal for creating interactive mixes of music, dialogue, and sound effects.

Eight audio output channels can be configured as eight mono or four stereo pairs. Any track can be dynamically routed to any output, with independent real-time volume control and pitch bend per output. A dedicated MIDI port with an integrated opto-isolator supports velocity-sensitive triggering, pitch bend, attack/release times, and per-key output routing.
