LoopBE30 is a common solution for adding Wireless MIDI connections to Windows machines.
MIDI ports must be connected sequentially, with LoopBE1 as input, and LoopBE2 as output, etc. LoopBE30 port naming does not distinguish between an input and output. Attempting to set both an input and output to the same named port will create a feedback loop.
LoopBE30 ports might present themselves to Lemur with different names than depicted below. Most commonly, you may see port names prefixed with “Internal MIDI”.
