alsa-project/alsa-utils issue #106 was opened from neilbags:

Hi, I'm using aconnect to send MIDI data from one USB MIDI device to another.

I need to filter the messages, so that only one MIDI channel gets sent through, or ideally, send data that comes in on one channel from device A out to device B on a different MIDI channel.

Is there any way to do this just with the command line tools?
