LoopBe1 is a virtual MIDI device driver that connects MIDI outports of one application to MIDI inports of another application. Acting as an "invisible cable," it facilitates the transfer of MIDI data between computer programs.

With LoopBe1, you can connect up to 8 applications to its inport and outport at the same time, making it incredibly versatile for all your MIDI transfer needs. And because LoopBe1 is a native Windows 2k/XP WDM kernel mode driver, you can expect the lowest possible latency.
One of the greatest things about LoopBe1 is that it works with every MIDI or DirectMusic capable application, so you don't need to worry about any special libraries or integration issues with your existing software.
Another great feature of LoopBe1 is its Systray Icon, which allows you to toggle the device on and off like a hardware device and view its status. Plus, LoopBe1 comes with powerful shortcut detection to avoid MIDI feedback. If a feedback loop is detected, LoopBe1 immediately mutes its port, interrupts the loop, and pops up a message so you can take action.
Lastly, LoopBe1 is free for non-commercial, personal use only, but if you want to use it for commercial purposes beyond a 30-day evaluation period, you'll need to purchase a commercial use license. Overall, LoopBe1 is a must-have tool for anyone working with MIDI data on Windows systems.
