One thing that is SUPER annoying in Ableton live for PC users is that when you start up Live you can’t plug in new Midi devices without restarting. I ended up hacking a way that I can plug midi devices in and out and wanted to share that. Also using this MIDI routing you can do some really cool tricks.
Midi Yoke and Miditrixs
Midi Yoke for Multiple Midi
MIDI YOKE is a MIDI Patch Cable driver. This allows you to connect the MIDI output from one program to the MIDI input of a different program or even device. MIDI Yoke can be configured to provide a varying number of MIDI Ports (from 1 to 16). In addition, each port allows multiple opens of both input and outputs: up to 4 openings per port. This flexibility provides for almost any configuration imaginable.
