NAME    [Toc]    [Back]

     midikeys -	3D graphical MIDI keyboard controller

SYNOPSIS    [Toc]    [Back]

     midikeys [Options]	<filename>

     [ -help ] [ -nofork ] [ -channel n	]

DESCRIPTION    [Toc]    [Back]

     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.

OPTIONS    [Toc]    [Back]

	  Print	usage statement.

	  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.

HARDWARE    [Toc]    [Back]

     midikeys works only on Iris Indigo	R4000, Indigo2,	Indy, O2, Octane, and
     Onyx/Challenge machines fitted with the SGI Audio Option (ASO) Board.

BUGS    [Toc]    [Back]

     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.
