Hubi's MIDI Loopback Device 2.5|
By Hubert Winkler
Hubi's LoopBack Device is a MIDI driver that adds virtual MIDI Ports (up to 4) to your system, which act as both, Input and Output MIDI devices. This enables you to "share" your current MIDI ports with multiple Windows programs at simultaniously. All MIDI data sent to the output (a typical sequencer program) is sent to all programs at the input side (eg. a MIDI monitor program). The ports are named "LB1" to "LB4" by default, but can be optionally renamed.

Warning: Windows 98 incompatibility problem
After installing this software for testing on Windows 98, Windows could not finish starting due to a fatal error in a function of MMSYSTEM.DLL called from MSGSRV32.EXE. Booting into safe mode and removing the driver fixed the problem. If the same thing happens to you, you can remove the driver in Safe Mode from: Start -> Settings -> Control Panel -> Multimedia -> Device -> MIDI Devices and Instruments. Select LB1 (or whatever you have named your Loopback port if you didn't leave the default) and clicking on Properties. Then click on Remove and reboot your system.
