SparkFun Tsunami Super WAV Trigger

Key Features

• Supports up to 4096 uncompressed 16-bit, 44.1 kHz mono or stereo WAV files
• Polyphonic – Play and mix 32 mono or 18 stereo tracks independently and simultaneously
• Trigger inputs can be individually inverted
• Seamless looping over arbitrary track length

Based on a new generation ARM Cortex M7, the Tsunami extends polyphony to 32 mono or 18 stereo simultaneous uncompressed 44.1 kHz, 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, dialog and sound effects. It supports true seamless looping over an arbitrary track length.

The big news is that the Tsunami has 8 audio output channels, arranged as either 8 mono or 4 stereo pairs. The mono version adds a new “ Synced Set” trigger function that can start up to 8 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).

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.
