SparkFun Qwiic Tsunami Super WAV Trigger extends polyphony to 32 mono or 18 stereo simultaneous uncompressed 44.1kHz, 16-bit tracks. The tracks can start, pause, resume, loop, and stop independently and have their own volume setting. The Qwiic Tsunami delivers true seamless looping over an arbitrary track length. The Qwiic system requires no soldering, but the Tsunami provides broken-out 0.1″-spaced pins for full access to each pin.
The SparkFun Tsunami Super WAV Trigger has eight audio output channels, arranged as either eight mono or four stereo pairs. Furthermore, alternate versions of firmware support either mono and stereo architecture. The mono version adds a “Synced Set” trigger function that can start up to eight mono tracks on adjacent outputs.
The Tsunami Super WAV Trigger has a dedicated MIDI port with an integrated optoisolator for quick connection to any MIDI controller. Tsunami’s MIDI implementation includes control of volume, pitch bend, attack and release times, and the ability to route any MIDI key to any of the output channels and specify single-shot or looping playback per key.
It is crucial to know that this is a 3.3V device, and its inputs – including triggers and serial RX – are not 5V tolerant. Additionally, the Tsunami Super WAV Trigger will only work correctly if the micro SD card is formatted with the correct file allocation size (32Kb). If this is set incorrectly during formatting, the Tsunami will show very erratic behavior and occasionally crash.
