Ok, but could "beatjazz" be played in an other way than Onyx did ?
If "beatjazz" can't be triggered pre-record patterns, it's pity (for me)
that the audience think it is...

By the way, if Flim had been created in 63 it would make a big difference
for me...
The context of a creation matters, don't you think ?

Cheers...

Ever tried the kind of high voltage piezo you get in ?
cigarette lighters?? MaybeY you can drop that across some high ?
value resistors to get an input suitable for an opamp stage. ?
You would need to remove the spring loaded housing. ?
They would be highly robust and able to
take a beating from a drummer more directly.?
