  • Trackpad Synthesizer: Command Line Options

    December 26th, 2010
    music, tech, trackpad_synth  [html]
    On the chinatown bus back from philly (which I was *very* lucky to catch) I moved all of the configurable options for the trackpad synth from compile-time to command-line specification. They are:
      -k [KEY]  Play in the given key.  Allowable keys are
                'A'-'G' followed by an optional '#' or 'b'.
                Default is D.
      -h        Harmonic minor mode
      -r        Relative minor mode
      -x        Mixolidian mode
      -K        A Klezmer mode (flat 2, sharp 6)
      -S        Send SKINI to stdout instead of MIDI from a
                virtual source.
      -V        Use the far left of the controller as a
                volume control.
      -o [N]    Divide the trackpad vertically into this many
                octaves.  Default is 5.
      -s [N]    Octave Shift: how far down to shift from the
                top of our range.  Default is 3.
      -v        Use velocity.  When pressing keys, set midi
                velocity to the finger width detected on the
                trackpad.
      -a        Send aftertouch midi messages based on how fat
                each finger is
      -c [N]    Send on channel N.  Default is 3.
      -p        Send channel pressure messages based on how fat
                all the fingers are on average,
      -P        Fake channel pressure using volume instead.
