Have you ever needed to change incoming MIDI data from different channels to one specific MIDI output channel? The MIDI Channel Changer/Combiner can be used to combine MIDI channels (1-16) onto a single MIDI output channel. Note that this unit operates via the MIDI IN and OUT sockets only and not through the USB connection.Operation:
The unit detects the incoming MIDI data, and if it is a MIDI channel command, converts it to a single MIDI channel which corresponds to the DIP switch MIDI channel (1-16) setting.
If any System Common, Realtime or Exclusive events are detected they are passed directly from the input to the output. System Exclusive messages will be sent until the End of System Exclusive message is received. However if a system realtime message is received during a System Exclusive message it is also passed to the output.Power Supply:
External power can come either from an AC-to-DC adapter or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack.
The board can operate on an external supply of 7 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.MIDI Channel Selection:
The MIDI Channel Changer Combiner commands are all channel (1-16) dependent. The system will also work with MIDI running status.
