I am working on some MIDI conversions and am looking for options that
people have been using for the electric valves used to open and close
the tracker bar lines. Options that are fast to respond, compact and
economical are encouraged. Please share sources too. Thanks in advance
for your help.

 [ Probably the most economical electric valves for orchestrions and
 [ organs are at eBay; search for "Reisner organ valve magnets".
