If with high level set to 1022 you still manage to reach 127 easily, maybe you should set the "All Gains Low " to "Yes"

And have you tried "Log1" instead of "Linear" curve?

I'm suggesting all this, but I know that you know (and Dmitri knows too) that there's a problem with your pad. Welcome to the club :P

It may just be my system, but I've experienced lag with fast rolls using Dmitri's Midi routing setup. Closing MIDI-OX and MCT and just running MD to BFD2 Magically improved the quality of the rolls. Try it out to see if the same is the case for you.

I now use MIDI-OX and MCT to get a solid but non-perfect setting, through experimenting and then fine tune with MD keys and ears on BFD2.

Don't forget CURVES. S1 turned my dynamic output from all-over-the-place to consistant.

Two things...

Lets start with the good news (and good advice), if someone else (using the crossbar method + roland cone replica + screen mesh head) experimenting problems with ghost triggering and/or false triggering and/or hot pad, dont be affraid to lower your piezo and unstretch the mesh head if you see that it bounces a little too much!
I finally found the perfect height for the piezo (and at the same time, the perfect height for the cone) and it makes a HUGE difference! I can now set my threshold to 6, retrigger to 3 and dynlevel to 3 !!!! The sound and the feel are much more naturel!

I used to see a bump where the cones touched the mesh head and it seems that was the problem. Now if I very gently run my hand over the mesh head (without putting ANY PRESSURE) I cant feel the cone. There`'s a space as thin as a hair seperating the mesh head from the cone. Any pressure on the mesh head will make contact with the cone and cause the piezo to detect the smallest signal (hot pads prefer small signals!).

I'm sure there are planty of reason why people get false triggering problem, but before buying mufflers or real roland cone or mess up with your MD, I really suggest you try this!


Now, second thing...
I have a new problem. :(
I've had this problem even before I made these changes with the mesh head and piezo. It's some kind of crosstalk problem. I say "some kind of" because it is not xtalk but something else that just looks the same!
My snare plays perfectly, my tom2 plays perfectly, but hitting the bass drum or tom1, also triggers my snare.
My snare is completely appart from the rest of the drum. Aned even if I put it 10 feet away from my kick and tom1, hitting the bass drum or tom1 still triggers the snare (and nomatter how soft or hard I play I always get a "1" value of snare).

G1 is my snare, C2 is my first tom (note that I'm playing very softly but for every hit on the tom I get a hit on the snare)
At first I thought it only happend in Battery because maybe I had accidentaly put 2 sounds over the same cell, but as you can see on the printscreen, the problem clearly shows up even in the MIDI monitor.

I noticed that you set Threshold on the snare very low thus making it too sensitive. You may be experiencing crosstalk due to electrical signal interference between wires.

One of my cymbals was going "chiiiing" when ever the kids switch on the light to the toilet next to the my musicroom. That pulled a few laughs.

Can a threshold of 22 on the snare also cause this kind of problem...

**Note that my foot is not even close to touching the hihat pedal, but still, it is triggered everytime I hit the snare.

It's been a while since the last post here. What problem?

Yeah that's right, but the problem is not necessarely linked to that previous case we were talking about.

As you can see on the printcreen, everytime I hit the snare I get about 6 to 16 values on my foot controller, even though my foot is not even on the pedal!
I've checked all the other pads, they dont trigger the foot controller like the snare does.
So I was wondering if maybe it could be related to my snare's threshold being set too low (current setting for threshold is 22, which doesnt SOUND too low). Otherwise I dont know how to explain why one hit on the snare should trigger couple of CC4 values!

I see. It shouldn't be happening with even lower threshold. You see to have either interference or a medium/high impedance bridge between tracks. Or there might be something wrong with a multiplexer. Try to swap the first two MUX ICs.

I had a similar problem crop up. Every time I hit the kick hard my high hat would play and could notice it in the MD vu. Turned out that I brought this on myself by cutting the tip piezo wire of my two zone high hat(just experimenting). Once I reconnected the wire the problem vanished.
Sure would like an explanation for this. But could also be a fix for others... check your wiring.
