2 x MBHP_DINX4 (only 6 74HC165 shift registers used)

2 x MBHP_DOUTX4 (7 74HC595 shift registers used)

1 rotary encoder (for tempo, could also be used for additonal purposes in future)

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.
