• Semitones knob: Rotate to set the pitch of oscillator 2—in semitone steps, over a range
of ±2octaves.
• Cents knob: Rotate to precisely adjust the frequency of oscillator 2 in cents
(1cent=1/100th semitone).
• Mix slider: Move to crossfade (set the level relationships) between the oscillators
(Shape 1 and Shape 2).
Use the Logic Pro Retro Synth Waveset menu
The Retro Synth Waveset menu lets you create and manage custom wavetables.

• Reverse Wavetable Order: Reverses playback of the loaded wavetable. For example, a
wavetable with 10 waveforms would sequentially play waveform 10 through to 1 when
reversed.
• Create Wavetable from Audiofile: Opens a file browser where you can choose an audio
file for use as a custom wavetable.
• Save Wavetable as: Opens a file browser where you can name and save your custom
wavetable.
• Delete User Wavetable: Removes the loaded user wavetable.
• Default Waveset: Loads the default waveset. You can switch between this and the
custom waveset.
• Custom Waveset: Loads the custom waveset. You can switch between this and the
default waveset.
Create a custom wavetable
You can create a custom wavetable from any audio file that contains one or more sections of
constant pitch. Where multiple sections are used, a section of silence should delineate them.
Timbral changes within sections are automatically detected with an adjustable parameter,
resulting in a wavetable entry for each timbral shift. You should limit the speed of timbral
changes within sections as very fast shifts can deliver unpredictable results.
If possible, use multiple audio sections with a constant pitch to create your source audio
file. A file with a constant pitch does not require the insertion of silence between sections.
1. In Logic Pro, open Table mode and choose Create Wavetable from Audiofile from the
Waveset pop-up menu.
Note: You can also drag a suitable audio file onto the Shape 1 knob.
2. In the File browser, choose the audio file.
3. Click the disclosure triangle at the lower left, then choose an item from the Analysis menu.
This parameter changes the sensitivity of detection within contiguous audio sections.
Choose the algorithm that works best for the audio material.
4. Choose “Save Wavetable as” from the Waveset pop-up menu, then name your new
waveset in the File browser.
The new wavetable name appears in the Waveset pop-up menu. Choose the name to
load it.
