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.

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine 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 memory card used to store files such as audio tracks. For this product, the card is where the sound files live, so its capacity and formatting can affect how many sounds you can 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.
- USB-C
- A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
