Spark Fun Robertsonics Wav Trigger Eurorack
IMPORTANT NOTE: Tsunami is a 3.3V ARM Cortex m7 device, and its inputs – including triggers and serial RX – are not 5V tolerant!
And so I have buffered the trigger inputs to the pcb with transistorized voltage dividers on each of 4 inputs. The switch connections to the pcb do not need to be buffered.
The module is configured to serve as a simple "one shot" drum sample player, with the added option to select from longer length "field recordings" when/if desired. However; long samples will drone on for the duration of their file lengths. Hence, I have added a stop button per each of 4 trigger channels.
Tsunami Specifications:

8 audio output channels, can be arranged as 4 stereo outputs. Route any track to any output
Outputs provide independent real-time playback rate control and MIDI Pitch Bend
Seamless looping over arbitrary track length
Trigger-to-sound delay: 8 msecs typ, 12 msecs max
Pause and resume individual or groups of tracks
Multiple random trigger ranges
16 trigger inputs are individually selectable for contact closure or 3.3Vcontrol
Trigger inputs can be individually inverted (active low or high)
Trigger inputs can be individually set to be edge, latched or level sensitive
Output volumes adjustable from +10dB to -70dB
Firmware track fades (attacks & decays)
A dedicated “Play” status digital output pin
Extensive serial control. Pin compatible with SparkFun FTDI Basic 3.3V

Unique to Tsunami
32 mono or 18 stereo voice polyphony
Dynamic routing to 8 mono or 4 stereo outputs
Play uncompressed 5.1 or 7.1 surround content with a single trigger
Independent real-time volume and playback rate control per output
Seamless looping over arbitrary track length
Dedicated MIDI I/O
Assign individual MIDI notes to specific outputs, with individual looping control
Line-level stereo audio input
Reset button allows changing SD cards without power-cycle
Firmware updates from microSD card. No additional hardware required
Tsunami supports feature configuration through the use of an “init” text (ASCII) file on the microSD card. An open-source, cross-platform (Windows, OS X and Linux) utility can create this init file automatically for you using a GUI interface:
