SWT16 Wav Expansion

1u Expansion for wav trigger backpack for SWT16

This is a 1u 8hp expansion for backpacking the sparkfun wav trigger onto a swt16.
You get:
Bank up and down
micro sd
out 1
out 2

Outs 1 and 2 and left-right respectively. If you save you wav files as panned hard left or hard right you essentially get two outs instead of one mono/stereo out.
Robaux's initial version of this project replaced the midi jack with the output jack but still had no way of controlling volume or switching banks and you had to take the module out to switch cards or copy new samples. This should help.
The first 12 triggers from the swt16 are tied to trigger ins 1-12. 13-16 on the wav trigger are dedicated to volume and bank switching. SWT16 13-16 are standard trigger outs. with that said trigger outs 1-12 are still active so its like a mult of the trigger with one going to the wav trigger and the other going to the swt16 trigger out jack.
