Hi all I'm trying to pick up user_name's idea and build a controller for a different drum module. The values I have measured are 5 V and 0.86 mA. Can anyone point out, how Bob S' circuit should be modified to match these values? I'm planning to use USB power since it is 5V and I can't tap...

Pardon me for jumping in. user_name, what drum module do you use?
