MIDI Channel Filter



Description:

The MIDI Channel Filter can be used to reduce MIDI throughput by removing MIDI System mesages. Also it allows one channel to operate a particular sound module/synthesiser, while filtering out the other MIDI channel data.

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 Filter commands are all channel (1-16) dependent. The system will also work with MIDI running status.
