midikeys - 3D graphical MIDI keyboard controller

[ -help ] [ -nofork ] [ -channel n ]
midikeys provides a 3D graphical MIDI keyboard controller interface used
to transmit events to an external MIDI device or the internal software
MIDI synthesizer. The MIDI Controllers panel is used to transmit a
plethora of MIDI controllers and monitor incoming data.
MIDI note data is transmitted by clicking the mouse on the music keyboard
or pressing the computer keyboard keys. See the OnLine book for the
computer keyboard to note mapping scheme. The position of the mouse
button click controls the note on velocity, with larger values generated
toward the front tip of the key. Key wipes occur when the mouse button
is pressed and dragged over the 3D keyboard. The Sustain switch (also
the Space Bar) will hold synthesizer notes but will not hold down the 3D
keys. This behavior is consistent with that of a piano.
midikeys can also operate as a player piano to visualize incoming MIDI
events sent from an external MIDI controller or from another application
such as soundplayer(1).
The sound may be changed by dragging a synthesizer preset or sound file
icon into the drop pocket.
-help
Print usage statement.
-nofork
Do not go into the background. By default, midikeys forks itself to
give control back to the shell.
-channel n
MIDI transmit and receive channel [1..16]
filename is a synthesizer preset or sound file.
midikeys works only on Iris Indigo R4000, Indigo2, Indy, O2, Octane, and
Onyx/Challenge machines fitted with the SGI Audio Option (ASO) Board.

There may be some rapid note retriggering if the mouse is clicked and
dragged in proximity to key boundaries. It is not possible to enter
specific pitch bend values in the front panel window because the typing
events are confused with input for the 3D keyboard. You can "stick"
synthesizer notes if you press the mouse rapidly on the keyboard, sustain
keys with computer keyboard and use menu to change octave, keyboard
length or MIDI channel, or if you hold down notes with computer keyboard
and lose application focus by moving mouse out of application window.
When MIDI Input Animation on for player piano simulation, systems without
graphics acceleration hardware will be burdened with CPU intensive
graphics operations.
