A Free Virtual MIDI Driver. LoopBe1 is an internal MIDI device for transferring MIDI data between computer programs. Basically LoopBe1 is an "invisible cable" to connect a MIDI outport of an application to any other application s MIDI inport.
All MIDI data sent to the program s output is channeled to the receiving applications in realtime.
You may connect up to 8 applications to LoopBe's inport and up to 8 applications to the outport, all sending and receiving at the same time.

LoopBe1 is a native Windows 2k/XP/Vista/7 WDM kernel mode driver, so expect the lowest possible latency. Due to its architecture, it doesn t work on Windows 95/98/ME. Programs do not need to link with special libraries, so LoopBe1 works with every MIDI or DirectMusic -capable application.

A System Tray Icon to Mute MIDI
LoopBe1 comes with a Systray Icon. You can switch it on and off like a hardware device and view its status.

MIDI Feedback - Shortcut Detection
Think of an application opening in- and outport of LoopBe1 and connecting both ports via MIDI through: you would get an infinite loop of MIDI data, circling in realtime, which would seriously slow down the whole computer. As modern MIDI applications may open several ports, this happens all too easily.

LoopBe1 has a powerful shortcut detection to avoid MIDI feedback. If a feedback is detected, LoopBe1 will immediately mute its port, interrupt the loop and popup a message. After disabling the malicious MIDI through within your program you can easily enable LoopBe1 again at its systray icon.
