Wav trigger pro and buttons

Sensors Sound & Audio
1

hi! i searched the documentation and the forum and i haven’t a clue.

i cant’ figure out what i need to do to control the wav trigger pro via buttons. in the past i worked briefly with the tsunami but i reckon the pro works in a different way.

i’m making a digital stompbox, the pro stores the samples and buttons activate the triggers.

here i can’t find much: Trigger Input Assembly - SparkFun Qwiic WAV Trigger Pro Hookup Guide

i don’t understand how to name the wav files and how to write the correct preset file, and i feel so dumb, sorry.

thank you so much for the help.

The WAV Trigger Pro is oriented around MIDI events, and the 8 trigger inputs are “hard-wired” to internally play MIDI Note numbers 1 - 8 respectively. A preset lets you define up to 8 actions per MIDI Note, so the triggers can have complex functions.

However, and this is the key point, when there is no preset on the microSD card, then the default preset is in effect, as described here, and the triggers are assigned to edge-trigger the first 8 tracks respectively.

Simply put, with no preset, trigger 1 will play track one (“0001_filename.wav”), trigger 2 will play track two (“0002_filename.wav”) and so on.

The naming is here MicroSD Card Preperation - SparkFun Qwiic WAV Trigger Pro Hookup Guide

The presets are a separate method, described here (you can also download sample versions)

The link you shared shows how to wire buttons up…it does operate very similar to your tsunami, in that the buttons will behave as trigger inputs that perform a function of your choosing

Thank you both so much!
