Snare Trigger Zones...

[clsimeone]

Disclaimer: When reading the following, please keep in mind that I know next to nothing regarding electronics and I'm doing a lot of reading.

I was thinking about the idea of trigger zones. Let's assume there are four triggers on a snare (left/center/right/rim)...

First, when a specific trigger is hit, can it some how turn off the other triggers or block their signals (some sort of relay I guess)?

Also, can each triggers signal be within specific frequency ranges (I guess by using resistors as some sort of filter)?

Then maybe a program like EDP (found on edrum.for.free.fr (http://edrum.for.free.fr)) can fire the appropriate sample based on a triggers frequency range. Of course the program would have to modified to process these frequency ranges.

If this idea worked then only one input would have to be used on the trigger/MIDI converter module and left-hand/right-hand snare samples could be fired the way they are played.

What do you think?

Thanks,
Chris

ummm....OK...dual zone drums have two triggers. never seen one with more than that. Center, is the head it self. It is buried in foam or rubber. The second trigger is attached to the shell.

Now, everything else you are talking about is controlled by stuff like Cross-talk (X-Talk), retriggter, filter envelopes, delay...........and the setting of all this stuff to work together.

You want the sensitivity on the two triggers set apart, but still be sensitive to play. Every trigger is different and every brain programs different.

suggest a long session reading the alternatemode.com, vdrums.com etc web sites.

I've seen the term x-talk used frequently. I understand it in the context of two wires next two or wrapped around each other. I believe twisted-pair was designed to eliminate or reduce x-talk.

Could you please explain...

How x-talk come into play regarding triggers?
What exactly is retriggering?
Thanks for those two links. I'll check them out.

Thanks,

x-talk is when you hit one pad, say a crash. It triggers the crash, but it also triggers a slight response from another, usually the nearest, pad. Such as the Tom 1. You then have to do some programming to reduce this problem. No big deal, but a pain. Unforutunately, sensitivity of the pad is also affected. People do some fun things to reduce it with out programming. newspaper in the rack tubes. I used that spray in house expanding foam sealer stuff and filled some of my tubes.

retriggering is that you want to allow the pad to react to hits in rapid succession, like a roll. but you also don't want it so sensitive that brushing your hand near a pad as you do a tom fill, results in notes played. again, one of those things where the brain has to be told what speed, sensitivity, softness, etc it will respond to and how.

When you buy a brain such as Alesis, they include a reference chart which has the major pads and what the Alesis people think you should program in as a starting point. Makes it very easy to get it set up in 15 minutes and then fine tune later.

Ray, thanks for the explanations.

Other than a rim/head type double trigger pad, the only pads I've heard of that are multi-sensing are Simmons SDX and the Wave Drum. They both use FSR technology, force-sensing resistors. Same technology used in DrumKATs. It virtually eliminates any interference between triggers. But I'm not sure how one would go about turning FSR circuitry (it's like a circuit with a rubber overlay...) into a useable multi-zone pad.

FSR is better than anything else out there, but making it useful is beyond most of us, or all of us. Unless someone knows otherwise.

Listen to Ray, he knows what he's taking about. Also, check out electronicdrums.com. You can see how to make a simple trigger and see how it works. Check the manufacturers' sites like: rolandus.com, pintechworld.com, hartdynamics.com. There's some good info on these sites.

See this thread here on GN for a bunch of other edrum links:
