Rate knob: Set the modulation speed. Can be synchronized with the project tempo when
Sync is enabled. See Sync button.
Depth knob: Set the modulation intensity.
Spread knob: Spread the delayed signal across the stereo field.
Frequency knob: Set the filter cutoff frequency.
Poles knob: Set the intensity of the phasing effect. Higher values result in a more
cutting and harsh phasing sound.
Tip: Where possible, try to use the minimum number of poles required because this
helps to reduce CPU load.
Feedback knob: Set the level of the delayed signal that is fed back into the input.
Mix knob: Determine the wet/dry balance (0% = dry only; 50% = equal mix; 100% = wet
only).
Sync button: Turn on to synchronize delay rates with the project tempo. See Rate knob.
Logic Pro Alchemy reverb effects
Effect modules are shown only in browse or advanced view. Click the Browse or Advanced
button to switch to either view, then click the Effect button in the Perform/Arp/Effects
section.
Effects in this group are used to add ambience to the signal.
Alchemy Acoustic Reverb effect parameters
High quality, full-featured reverb effect.
Time knob: Set the length of the reverb tail. Values up to 20 sec are possible.
Pre Delay knob: Set the amount of initial delay before diffuse reflections begin.
Size knob: Determine the dimensions of the simulated space.
Width knob: Determine how much reflections are spread across the stereo field.
Diffusion knob: Determine the density of the early reflections.
Gate knob: Set a threshold below which the reverb tail is gated. Attack shapes the
beginning of the gated tail, while Decay shapes its end.
Attack knob: Attack shapes the beginning of the gated reverb tail.
Decay knob: Decay shapes the end of the gated reverb tail.
EQ knobs: Modify the frequency content of the wet signal. LoFreq sets the frequency of
a low shelf that you can boost or cut with LoGain. HiFreq sets the frequency of a high
shelf that you can boost or cut with HiGain.
Damping knobs: Determine the amount of frequency-specific losses (damping).
DampLoF sets the frequency of a low shelf that you can damp by increasing
DampLoAmt. DampHiF sets the frequency of a high shelf that you can damp by
increasingDampHiAmt.
Variation knob: Determine the reverb color.
Quality knob: Determine the processing precision. Use low values to conserve CPU
resources.
