I think, it is not necessary to clone the whole SDX. The whole sampling and
sound stuff with the nine sounds per pad, the sampling itself, the storage
a.s.o. can be easily made by an old Akai or something else. But it would be
a good idea to build the input interfaces which are located on the first SDX
PCB and the ZI thing. I am working on that and I have drawn a rough
schematic of the standard ZI input (still not ready: the 2 piezo inputs of
kick and snarerim and also the pedals).Anybody who wants to have that for
own experiments: I share it of course for free. I am working on ZI pad
clones also, but this might take some time. But I am glad to have all
materials together to build these FSRs. I also found a way to play
"ordinary" synthdrums (SDS 3,4,5,7,8,9) with a ZI pad (!) and I am working
on a solution to play SDX with a "normal" piezopads (sure, I know, the zone
information will be lost, but most of SDX owners don't have 16 ZIs and
perhaps they will be glad to use ALL channels somehow. And a cowbell for
example needs no zone intelligence).
