TK. Posted October 14, 2014 Report Share Posted October 14, 2014 Al Spitzley created a compact PCB for this purpose, here a picture of the prototype: It provides 16 gate triggers and even 10 CV outputs for velocity sensitive drums. I'm not sure if and when he would like to run a batch order, you could ask him nicely. Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
