Alchemy Arpeggiator Step edit mode parameters
• Edit Mode buttons: Use the Step or Multi button above the to choose the sequencer
view and edit mode.
• Target pop-up menu: Choose the parameter to view and edit.
• Velocity: These values set the velocities of notes generated by the arpeggiator,
assuming the Note Vel knob is not set to 100%. Set a step value to zero to create a
rest. No note is played on that step.
• Tune: These values determine tuning offsets for each step in semitones.
• Pan: These values set the pan position of individual notes: drag up to pan the note
left, or down to pan right.
• Swing: These values determine timing offsets that make individual steps play
early or late. The Swing sequence and the Swing knob can be used at the same
time, allowing you to add a basic shuffle feel with the Swing knob, then fine-tune
individual notes with the Swing sequence.
• Length: These values set the note length for each step. Steps with zero length do
not play. The Length knob globally scales the durations of all steps, but you can
refine these lengths with the Length sequence. Try setting even-numbered steps
shorter than odd-numbered steps, for a funky, groovy feel.
• Arp Mod 1-2: Use these general purpose sequences to modulate any of the main
synthesizer parameters: ArpMod 1-2 is available as a modulation source. See Logic
Pro Alchemy note property modulators.
• Value Snap pop-up menu: Set a value that automatically snaps edits you make to
sequence steps. For example, set to 1/3 to limit edits to 100%, 66%, 33%, or zero
values. Off disables quantization, which lets you set step values freely.
Note: Value Snap doesn’t move existing step values into alignment with quantized
positions; it only affects the response of step values when you move or create them in
the step editor.
• Scroll bar: Drag the middle of the scroll bar to view steps that are not visible in the
display area.
Alchemy Arpeggiator Multi edit mode parameters
• Gate On buttons: Turn individual steps on or off. These buttons actually display the
Velocity sequence values, with any step value greater than zero displayed as on.
Switching to Multi edit mode from step edit mode does not change existing Velocity
sequence values. However, if you turn off a step in Multi edit mode, then turn it back on,
that step is set to 100% rather than its previous value.
• Tie buttons: Perform the same function as the tie buttons under each step in step mode:
the step is tied to the next to make one longer note.
Note: Any Velocity sequence value greater than zero is ignored for the subsequent tied
step, as is the Pan sequence value. Pitch offsets work for the tied steps, however, so
you can create pitch glides over tied steps by adjusting the Glide value in the master
voice section, setting the Num(ber) of voices to 1, and setting the voice mode to
Legato. See Logic Pro Alchemy master voice section.
• Tune fields: Drag vertically to set tuning offsets for each step in semitones. Double-
click to reset the offset to zero.
