• FlipFlop: A modulation signal that is alternately full-scale and zero on successive
notes.
• FlipFlop2: LikeFlipFlop, but the value reverses every two notes: zero, zero, full, full,
in a repeating pattern.
Note: The FlipFlop modulators can be used together to create a round robin
involving all four sources. To do this, set Morph mode to Morph XY or XFade XY, set
the Morph X and Y knobs to 0%, then modulate X with FlipFlop and Y with FlipFlop2
or vice versa. See Logic Pro Alchemy morph controls.
• Stepped4/8/16: Similar to FlipFlop, but cycles between the number of values (4, 8, or
16) at each subsequent note-on. Steps are spaced at equal increments, starting from
a value of zero. If you need further control, you can use a ModMap to define values
for each step. See Logic Pro Alchemy ModMap.
• Random1-4: Modulation based on a fixed random value per note. This is a unipolar
source with values ranging from zero through full-scale. The four random sources
are independent of each other.
• PitchBend: Modulation based on MIDI pitch-bend messages. This is a bipolar source
with values ranging from negative full-scale through positive full-scale.
• Max: Modulation based on a constant full-scale value.
• Polyphony: A modulation signal that is larger when there are more notes playing
and smaller when there are fewer notes playing. Technically, the current number of
played notes is divided by the total polyphony. This parameter may be useful for
reducing volume when lots of notes are played. Polyphony is determined by the Num
parameter in the master voice section. See Logic Pro Alchemy master voice section.
• ArpMod A/B/C/D 1-2: Assign parameters for arpeggiator control.
The assigned parameters are controlled by the arpeggiator. The Poly Mod 1 and
Poly Mod 2 pop-up menu assignments in the arpeggiator correspond to these
parameters. When the arpeggiator is in All mode (denoted by the A), one arpeggiator
is used for all sources. When you use multiple arpeggiators to control individual
sources, Poly Mod options A/B/C/D are shown in the Note Properties pop-up menu.
See Logic Pro Alchemy arpeggiator sequencer.
Logic Pro Alchemy perform control modulators
Modulation components are shown only in advanced view. Click the Advanced button to
switch to advanced view.
You can choose one of sixteen different modulation sources from the Perform submenu
in the modulation rack. These correspond to the eight assignable knobs, two X/Y control
squares, and four envelope knobs shown in the perform section.
Set performance controls as modulators in the modulation rack
1. In Logic Pro, click a slot in the modulation rack, then choose Perform from the pop-up
menu.
2. Choose one of the following perform section control options from the submenu:
• Control 1-8: Assignable knobs, numbered 1–8.
• XYPad1X: The X (horizontal) axis of the left XY control square.
