Robertsonics WAV Trigger

Under works is PCB and frontpanel for Robertsonics WAV Trigger that I bought from Spark Fun Electronics (https://www.sparkfun.com/products/13660). The PCB and panel creates a frame where WAV Trigger can be fitted. Simple transistor circuits work as comparators that can be fired either from frontpanel switches or from external CV/GATE input voltage (anything between +-10V is OK). My idea was to use this sample player to play some pre-recorded sounds in live-situations. It is polyphonic (max 16 voices) so several samples can be played at the same time. This could also work as a drum machine where drum samples can be triggered from external triggers.
