CCs/Pitch Group
Overview
The CCs/Pitch Group allows the editing of parameters
that control generation of CC (Control Change)
messages. For example, this can control the panning
(CC #10) of the notes in the Generated Effect (stereo
placement left to right). Any other CC data may also be
generated to control any MIDI controllable
characteristic of your synthesizer, such as resonance,
filter frequency, vibrato, etc. You may also use the CC
Pattern to generate stepped Pitch Bend messages,
technically not a “CC.” Depending on internal settings
of the GE, the CC Pattern may also be used to specify
“Pitch Offsets” that will be applied as Transpose
Values to each note as it is generated. This can be used
to simulate the Triton Arpeggiator Pitch Offset value
for each step, in addition to providing other interesting
and useful effects.
About CC/Bend/Pitch Patterns
A value derived from a CC/Bend Pattern is a MIDI
Control Change value from 0–127 (or Pitch Bend, or
Pitch Transpose Values, if selected). The values are sent
out as each note or cluster of notes is generated.
Choices can be made from “Random Pools” of values
as described in detail later on.
If the selected CC is 10 (Pan) for example, a CC Pattern
such as {0, 127} would cause every other note to pan to
the opposite side of the stereo spectrum. A CC Pattern
of {0, 0, 0, 0, 127, 127, 127, 127} would play four notes
left, then four notes right. A CC Pattern may be
inverted at any time (caused to go in the opposite
direction, 127 – 0) by using the Polarity Parameter,
which is an easy way to reverse the direction of the
pattern.
A CC Pattern will loop as long as note generation
continues. It normally will not reset to the beginning of
the Pattern unless a new Trigger is received, or unless
the Phase Group has been configured to restart it at the
beginning of certain Phases. This means that a four
step CC Pattern can be looping while an eight step
Velocity Pattern and a twelve step Cluster Pattern are
also independently looping, for example.
Pattern Grid & Associated Parameters

CC Pattern
A CC Pattern represents a series of values indicating a
MIDI Control Change (or Pitch Bend) value to be
generated. It may have any number of steps up to 64,
and loop independently of other patterns being used at
the same time. Each step is represented by one column
on the grid. The first column always contains at least
one value. Each row represents a CC or Pitch Bend
value in multiples of four (0, 4, 8, 12 etc.). The special
bottom row (“inv”) indicates whether or not to invert
the Random Weighting Curve (discussed later on) for
any pools within that column.
Depending on internal settings of the GE, the Phase 2
CC Pattern may be used to specify “Pitch Offsets” for
notes as they are generated. In this case, the grid is split
into two portions: the top portion (Pitches) contains 25
rows, corresponding to a Transpose value of -12 to +12
semitones. The bottom portion (Octaves) contains 7
rows, corresponding to a Transpose value of -3 to + 3
octaves. By combining the two Transpose values, any
offset from -48 to +48 can be achieved. This can be used
to simulate the Triton Arpeggiator Pitch Offset value
for each step, in addition to providing other interesting
and useful effects.

Associated Parameters
Fixed On [0…128]
When set to 128, the Pattern Grid becomes operative,
and the Pattern is sent out. When set to any other
value, a single CC or Pitch Bend value corresponding
to the fixed value is sent, and the Pattern Grid becomes
inoperative. This allows you to override the Pattern
with a fixed value.
