MidiCC support in the Patch Editor will allow systems that can only output
MidiCC to control any synth that the Patch Editor supports.
The Patch Editor can have any standard MIDI channel (1-16) set independently for each synthesizer
selected and the MIDI channel for MidiCC control to the Patch Editor can also be set. These are
remembered when the Patch Editor is switched off. It is possible to send commands to the Patch
Editor on one midi channel and the Patch Editor will output to the synth on another. This could be
useful if the control codes to the Patch Editor could be interpreted differently by the synth being
controlled.
All incoming MIDI except for commands to the Patch Editor are passed through to the MIDI out port.
All output from the Patch Editor also uses this MIDI port and this output is interlaced with any
incoming MIDI data. This introduces a 1-3mS delay as the commands are interpreted and resent.
This must be done so as the incoming MIDI can be mixed with the MIDI generated by the Patch
Editor without breaking MIDI strings. The MIDI running status byte needs to be reinserted if the
incoming string has a running status byte that has been interrupted by the Patch Editor sending out
commands. MIDI real time signals (clocks etc) are put directly to the output for a minimal delay
which is normally about 100µS no matter what is happening within the Patch Editor. All incoming
MIDI is passed to the MIDI through port without delay.
If a time critical MIDI unit is part of the chain then this should be run from the MIDI Through port to
reduce delays
.
If the Patch Editor midiCC command set is being used to translate to sysex be
aware the the Patch Editor may need to send much more date than it receives so
it is important that not too much data is sent too quickly or the Patch Editor
buffers will overflow resulting in corrupted midi. This will cause random errors
like stuck notes.
Power requirements are a single 9-12vDC supply at 500mA. 9v is preferred to stop the PE getting
too warm. The polarity is marked on the Patch Editor and it is protected against reversed power. It
was decided not to include a power unit with the Patch Editor as these are country specific and
easily purchased throughout the world. A universal voltage power pack can be provided if required
but it has a New Zealand plug format and will require adapter plugs for use in other countries.
Note: From serial number 001135 and higher the DC Plug polarity has been changed to the
more standard positive tip / negative shell.
