Sound controlled stage lighting Answered

Ladies and Gents:

I am seeking help from you guys. I am in a band and want to build something that can control some lighting we have. I am looking for it to be controller by the drummers kick pedal or my bass. Ideally, everytime a certain sound is created i want the light to go on then off. Kinda like a strobe light but only at certain times (the kick pedal of when a certain sound comes from the bass). If you guys have any ideas, let me know. Here is an example of how I'd like it to work. Thanks for any help.


This can all done through midi triggering. Having a pad that you can hit to trigger the signal sent to your pre programed dmx lighting scenes.

I have been trying to figure out a device like this as well. My idea was to use a relay with a 12VDC coil. My thought was run my hot line of my light through the common and normally open terminals on the relay than hook the input coil to a piezo attached to the bass drum. The problem I ran into is when the piezo is hit my voltage output is relatively low, too low to switch the relay. I need a fairly simple affordable way to boost that output. Any suggestions?

. For the drum, a piezo element should make a good trigger. . To pick out different notes, you'll need something like a narrow bandpass filter. . Good song, but I could do without the growling.
