[net.music.synth] midi and the JX3P

kurtenba@sask.UUCP (Gordon Kurtenbach) (11/13/85)

Does anyone out there know how to set up a Roland jx3p so it responds to
only one particular midi channel? The manual that I have has about a cpu's
cycle worth of information in it about midi.

				Thanks,

  The JX-3P was one of the first synthesizers to incorporate MIDI built in
  to the synthesizer and as such has some severe limitations.  One such
  limitation is the inability to respond to a single channel.  The original
  unit was designed with OMNI mode permanently on!  What this means is that
  the JX-3P will always respond to all 16 channels.  However it will only
  transmit on channel 1.

  Enter the JX-3P upgrade PROM.  With this new chip installed, your JX-3P
  can be made to respond to only channel 3.  Selecting this option however
  disables the keyboard and you can only control the JX-3P as a slave.
  Power cycling will cause it to return to normal OMNI mode.  The PROM is
  (or was) available direct from ROLAND at about $50.  As the JX-3P is not
  produced any more, I'm not sure if the still have the PROM for it.
