For your info, we make (digital pressure regulated) MIDI chests with
full ranks -- the standard chest is 32 notes, D to A, but I don't see
why it could not be extended to 61 notes -- of Decap/Mortier voices,
so if there is MIDI available these chests can be hooked up without
any problem. A tube with unregulated air is sufficient.

The original JazzFlute and Vibratone voices use little valves in the
back of the pipes, but as our chests have excellent control over the
pressure, we use a vibrato/tremolo air pressure change to create a
similar (and in my opinion, nicer) vibrato. More info on www.decap.be
