Hi Rob, Hello All,
Just upgraded to 2.3.0.12 and decided to give a chance an old 12" Alesis pad with regards to positional sensing for 3-cone pads.
Until now I was busy with my own setup based on teensy and 3 cones with a simple trilateration algorithm on 14" and real-feel (midi from teensy goes through edrumin 10) - I got inspired by
https://github.com/corrados/edrumulus, but instead of trying to understand just wrote my own. So for those of you who would like to go this way - it works.
Anyway, back to the main topic - the Alesis pad has complicated construction, but definitely NOT based on 3 cones. It did not work previously with positional sensing either, esp. with real feel...
So I was very surprised when I discovered, that using the 3 cones settings it works reliably. Surprise. This is Rob to let you know, I guess you asked for it at the beginning of this thread. Honestly, I don't know why or how it is possible, etc. - one thing is clear though: you created a wonderful piece of hardware & software and it really goes beyond any imagination now
For Rob (who will be probably curious why it works) and those interested in this pad: all I know about is it has printed on the bottom U.S. Patent 9,424,827
So you can take a look at its construction:

Maybe you guys already have an old stuff somewhere - worth trying, just to let Rob know how and where to go further with this great 3-cone idea.
Regards,
GC
Btw. my idea for further development would be to try to go edrumulus' path, like eg. try to encode signal from 3 piezos (I do not know much about electronics, thus used teensy with 3+1 piezos and some basic setup: diodes+resistors) and use trilateration - then one can quite exactly know the point of hit. And this would open the new 3-cone world for diy-ers.

... and in the end we may achieve more sections/zones on snare
