The forthcoming Wiard Mini-Wave will also act as a voltage
quantizer. The following scales are programmed into the
EPROM that ships with the unit.

Bank 15: Quantizer Bank

Control Voltage Quantizer Mode
+/- 5 volts input give 0-5 volts output (5 Octaves)
Run control voltage to WS In and run WS Out to 1V/Octave input on
oscillator, Set output switch to 10 volt range

Wave Number:
0  Chromatic 12 notes per octave (4 steps per note)
1  Diatonic Major (C-D-E-F-G-A-B) Eight per octave (6 steps per note)
2  Diatonic Harmonic Minor (C-D-D#-F-G-G#-B) Eight per octave (6 steps per
note)
3  Diatonic Natural Minor (C-D-D#-F-G-G#-A#) Eight per octave (6 steps per
note)
4  Diatonic Dorian Mode (C-D-D#-F-G-A-A#) Eight per octave (6 steps per
note)
5  Diatonic Phygian Mode (C-C#-D#-F-G-G#-A#) Eight per octave (6 steps per
note)
6  Diatonic Lydian Mode (C-D-E-F#-G-A-B) Eight per octave (6 steps per note)
7  Diatonic Aolian Mode (C-D-E-F-G-G#-A#) Eight per octave (6 steps per
note)
8  Whole Tone (C-D-E-F#-G#-A#) 6 notes per octave (8 steps per note)
9  Pentatonic (C#-D#-F#-G#-A#) 5 notes per octave (10 steps per note)
10  C Major (C-E-G) 3 notes per octave (17 steps per note)
11  A minor (C-E-A)
12  G Major (D-G-B)
13  F major (C-F-A)
14  D major (D-F#-A)
15  Octaves one note per octave (46 steps per note)
