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.

Key Features

32 Mono / 18 Stereo Polyphony – Mix simultaneous uncompressed WAV tracks
8 Audio Outputs – Configurable as 8 mono or 4 stereo pairs with independent volume and pitch
Up to 4,096 WAV Files – 16-bit, 44.1 kHz, CD-quality audio from microSD
Seamless Looping – True seamless loops over arbitrary track lengths
16 Trigger Inputs – Individually configurable for contact closure or 3.3 V logic, edge/latch/level sensitive
Dedicated MIDI Port – Opto-isolated, with velocity triggering, pitch bend, and output routing
Synced Set Function – Start up to 8 mono tracks in sample-sync for surround sound (5.1/7.1)
Qwiic / I2C Interface – Solderless connection, plus 0.1″ breakout pins
Low Latency – 8 ms typical, 12 ms maximum trigger-to-sound delay

Resources

Jargon buster

Plain-language definitions for the technical terms used above.

breakout: A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
I2C: I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
microSD card: A microSD card is a small removable flash memory card used to store data such as audio, images, logs or program files. Its capacity and formatting (often FAT32 or exFAT) affect how much can be stored and whether the card needs preparing before use.
MIDI: MIDI is a standard way for electronic instruments, controllers, and software to send musical control messages such as notes, velocity, and timing. If a board supports MIDI, it can be triggered from keyboards, drum pads, sequencers, or other music gear rather than only from buttons or code.
PTH: Plated through-hole means the pin holes are metal-lined so solder connects the pad on both sides of the board. It is useful for connectors and headers that need a strong mechanical and electrical connection.
Qwiic: Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
RX: RX means receive, usually showing data being received by the board. An RX indicator LED can help with troubleshooting USB or serial communication.
USB-C: USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
