How to have multiple programs use the same MIDI interface?

Post by rtmusic »

I am using a Raspberry Pi 4 to record MIDI using an iConnectMidi1 USB interface. I can use the arecordmidi command to record MIDI input. However while I am doing this I cannot access the same interface by other programs. It is not available if I try to run a separate arecordmidi session or another sequencer. I am recording lengthy sessions, (hours). I'd like to do a straight recording on my Pi, but also stream the playback to other devices using RTP MIDI. Is there a way to allow the same interface/input stream to be used by multiple applications simultaneously? Thanks!
