Alchemy Delay effect parameters
Stereo delay with dual-filtered feedback.
• L/R Rate knobs: Set the delay time in msec when the Sync button is off, or in beats
when the Sync button is on. See Sync button parameter below.
• L/R Offset knobs: Add a small additional amount of delay, enabling you to adjust the feel
of tempo-synced delays.
• L/R Feedback knobs: Determine the amount of delayed signal fed back to the input of
the delay.
• Filter A/B buttons: Turn on to filter the delayed signal without affecting the dry signal.
You can use one or both filters. Select a type for each filter via the selection fields. Each
filter has Cutoff and Resonance controls.
• Filter type pop-up menu: Choose a type for each filter. See Logic Pro Alchemy filter
types.
• Cutoff knobs: Set the filter cutoff frequency for filter A or B.
• Resonance knobs: Set the filter resonance or emphasis for filter A or B. Higher settings
boost frequencies in the immediate vicinity of the cutoff frequency.
• Sync button: Turn on to synchronize delay rates with the project tempo. See L/R Rate.
• Mono button: Turn on to mix the left and right input channels down to mono. The result
is fed to both the left and the right channels of the delay. The dry portion of the signal
remains in stereo.
• Crossover knob: Determine stereo placement of the feedback signal. At 0%, left feeds
left and right feeds right; at 50%, each channel is fed to both inputs; at 100%, left feeds
right and right feeds left.
• Initial Pan knob: Determine stereo placement of the initial delayed signal (prior to
Feedback). Typically, you would set Initial Pan to 0% or 100% when Crossover = 100%,
and leave Initial Pan centered at 50% in most other cases.
