Drum Simulator Pots

Drum Simulator Pots

2008-07-07 by ErezYaary

Hi,

After building my Drum Simulator and firing it up, it reacts well to triggers as well as a nice
basic sound.

The only issue is that the pots have no effect on the sound. I have connected them each to its
respective double POT[x] connectors on board.

Anything I might be doing wrong?

Thanks,

Erez Yaary

Hello Erez,

I just completed this module tonight and have the exact same problem. Tried to troubleshoot for awhile to no avail. Did you ever figure out the problem?

My guess is that you have used one of the new breed of super-bright LEDs with a 3 volt drop. This circuit was designed around the old fashioned LEDs that had either a 1.6 volt or 2 volt drop. You could try putting 2 or 3 1N4148 in series instead of the LED. The LED was never meant to be panel mounted, so hopefully you haven't put it on your panel!

Ian,

Well, it was some time ago and I do not recall what I did to solve it. Usually my build errors were around missing to solder a connection (I solder fast and tend to overlook a joint every other board), shorting two joints or a screwed up tranny / IC. it might have been the case in the drum sim.
