This program primarily simulates a MIDI keyboard which you can play
with the mouse or the computer keyboard. You can control your MIDI
devices without having a real keyboard - for example you can play the
internal synth of your sound card. With a virtual MIDI cable (for
example Hubis Loopback Device or MIDI Yoke) you can play any sequences
into your sequencer or route your external synthesizer through the
chord-maker of Bome's Mouse Keyboard. Additionally, you can define as
many knobs as you want and control with them any MIDI controller.
