Axiom Controller Configuration

The Rotor Organ code has naturally evolved to match my own setup, so here I describe the patch for my Axiom Keyboard Controller. You can probably configure other units in a similar way.

• The keyboard itself drives the Upper/Swell Manual on Channel 1. (I use my piano for the Lower manual on channel 2.)

• The Nine Faders of course stand in for one set of Drawbars. The Axiom allows me to reset the range, so full-scale is 0..8 (increasing downward) to match a Hammond.

• The Buttons are set up as toggles (alternate presses switch between states) to control Vibrato/Chorus and Percussion:
  • 1: Vibrato/Chorus Off Ch. 3 CC20 = 64 (no toggle)
  • 2: V1/C1 Ch. 3 CC20 = 86/43
  • 3: V2/C2 Ch. 3 CC20 = 106/22
  • 4: V3/C3 Ch. 3 CC20 = 127/0
  • 5: Upper Manual Vibrato On/Off Ch. 1 CC80 = 127/0
  •     then, from the right… (6 is unused):
  • 9: Percussion On/Off Ch. 1 CC81 = 127/0
  • 8: Percussion 2nd/3rd Ch. 1 CC82 = 0/127
  • 7: Percussion Slow/Fast Ch. 1 CC83 = 0/127

• Three of the Trigger pads control the Leslie:
  • 1: Leslie Off Ch. 3 Key #21
  • 5: Fast Leslie Ch. 3 Key #24
  • 6: Slow Leslie Ch. 3 Key #27

• Six of the Encoder Knobs are used:
  • Lower Row:
  • 5: Overdrive Ch. 3 CC21
  • 6: Spring Reverb Ch. 3 CC25
  • 7: Room Reverb Ch. 3 CC26
  • Upper Row:
  • 2: Percussion Amplitude Ch. 3 CC22
  • 3: Percussion Fast Decay Ch. 3 CC23
  • 4: Percussion Slow Decay Ch. 3 CC24
