constantly sampled and a new note is output as soon as X moves into the next semitone range.)
Parameter 2 sets the root
key
of the chosen scale. At zero, the first note of the scale (e.g. C in the
key of C) corresponds to 0V. If the parameter is set for example to 2, the first note of the scale is at
2/12 = 0.1667V - or to look at it another way, if your VCO is tuned so that 0V gives you a C, the
quantizer is now working in the key of D (D major, minor, triad etc. depending on the scale setting).
Parameter 3 sets an offset between the timing of the X & Y inputs (in sample frames). When using
Y as a trigger, it is often a good idea to delay it slightly relative to the pitch, to ensure that the pitch
has changed and settled before the trigger samples a new note.
Parameter 5 applies transposition, exactly as per the description of using Y for transposition above.
Note that transposition with parameter 5 is always available, even if Y is being used as a trigger.
MIDI Output
: each new note (i.e. when the Output B trigger fires) is output as a MIDI note
message on the MIDI channel selected in the settings.
Parameter 4 controls when note off messages are sent. If parameter 4 is zero (the default), the note
off is sent just before the note on – so the note lasts from one change to the next, which is
conceptually the same as the CV output. If parameter 4 is one, and Z is negative (so Y is a trigger),
then the trigger is treated as a gate, and the note off message is sent when the gate goes low.
Additionally, in this case, a MIDI note on is sent for each trigger, instead of only when the note
changes.
MIDI Input
: MIDI note messages received on MIDI channel 1 are used according to parameter 6.
If this parameter is 0, MIDI notes set parameter 2 (root key).
If parameter 6 is 1 or 2, the candidate notes for quantization are set via MIDI. The algorithm listens
for MIDI note on messages and uses the received notes for the quantization pattern. While any
notes are held, playing new notes adds to the pattern. When all notes are released and a new note
played, the pattern is reset and formed from the new note.
If parameter 6 is 1, the played MIDI notes set the note names, but quantization can happen in any
octave (i.e. if you play a 'D' the output will always be 'D' but the octave will depend on the octave of
the incoming CV).
If parameter 6 is 2, the played MIDI notes are the only ones that can be output (so say if you play
middle C and the D above, the output will always be one of those two notes, depending on whether
the input CV is below or above middle C).

Output A is a gate signal (zero or +5V), high when input X has a higher voltage than input Y.
Output B is an inverted copy of A (i.e. +5V when A is 0V and vice versa.)
The Z knob/CV input sets the hysteresis (for an explanation of hysteresis see
). Inputs of
approximately 0-4V correspond to hysteresis values of approximately 0-10V. Negative values are
