Based on a new generation ARM Cortex M7, this version of the Qwiic Tsunami Super WAV Trigger extends polyphony to 25 mono or 13 stereo simultaneous uncompressed 44.1kHz, 16-bit tracks. Each track can start, pause, resume, loop, and stop independently, and can have its own volume setting, allowing you to create the perfect interactive mix of music, dialogue, and sound effects. The Qwiic Tsunami also supports true seamless looping over an arbitrary track length. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1″-spaced pins in case you prefer to have full access to each pin.

The big news is that the Tsunami has eight audio output channels, arranged as either eight mono or four stereo pairs. Alternate versions of firmware support either mono or stereo architecture – you choose. The mono version adds a new “Synced Set” trigger function that can start up to eight mono tracks on adjacent outputs. These tracks will start and stay in sample sync for playing stereo or even 5.1 or 7.1 surround sound content with a single trigger. Any track can be dynamically routed to any output. And each output provides independent real-time volume and sample-rate conversion (pitch bend). For your convenience, the Tsunami also has full Arduino and Python libraries available which can be found in the Documents tab above!

Each Tsunami Super WAV Trigger has a dedicated MIDI port with an integrated opto-isolator, making it easy to connect 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, as well as specifying single-shot or looping playback per key. It is very important to know that this is a 3.3V device, and its inputs – including triggers and serial RX – are NOT 5V tolerant!

Note: The Tsunami Super WAV Trigger will only work properly if your µSD card is formatted with the correct file allocation size (32Kb). If this is set incorrectly during formatting, then the Tsunami will show very erratic behaviour and occasionally crash.
