• Low Cut knob: Set a cutoff frequency. All signals above this frequency are allowed to
pass. Signals below the frequency are cut.
• High Cut knob: Set a cutoff frequency. All signals below this frequency are allowed to
pass. Signals above the frequency are cut.
The Low Cut and High Cut parameters work in conjunction with each other to act as a
bandpass filter, where signals that fall within the two cutoff ranges are allowed to pass.
Logic Pro Alchemy spectral element effects
Source components are shown only in advanced view. Click the Advanced button to switch
to advanced view, then click the A/B/C/D button to select the source you want to edit.
Alchemy spectral element effects provide a number of creative options in the spectral
synthesis engine. Two effects units are available in the lower half of the spectral
parameters shown in the source subpage. See Logic Pro Alchemy spectral element controls
for information on other spectral element parameters.
Note: You must first perform a sample import with a spectral analysis or draw in the
Spectral edit window before you can use any of the spectral engine parameters. See Logic
Pro Alchemy Import browser and Logic Pro Alchemy spectral edit window.
Spectral effect parameters
• Spectral effect on/off buttons: Enable or disable the spectral effect unit.
• Spectral effect pop-up menus and fields: Choose a spectral effect type. See spectral
effect descriptions below.
• Mix knob: Set the balance between the original signal and the processed sound. This
parameter is common to all spectral effect types.
• Parameter knob 1: Set the value for the parameter assigned to the chosen spectral
effect. The parameter name and function vary with each effect type.
• Parameter knob 2: Set the value for the parameter assigned to the chosen spectral
effect. The parameter name and function vary with each effect type.
• Parameter knob 3: Set the value for the parameter assigned to the chosen spectral
effect. The parameter name and function vary with each effect type.
