Greetings, all.

In a recent flier from Ragtime, there are some photos which show the
little pneumatic valves.  These little $5 valves appear to be about the
size of a thimble and are intended to be inserted inline for the purposes
of MIDI *playback* only.  They operate on 9-14 volts dc.

You still need to provide your own "MIDI-IN" processor board, of which
there are several available, as you know.  By using John Wale's low cost
MIDI board, MIDI upgrades can be relatively low cost.  How does Ragtime's
$5/per note valve compare to others?  Someone please run some tests and
let us know how the Ragtime valves perform.

For more information about "MIDI-IN" boards, please see my page at:
