Use the Retro Synth Wavetable menu in MainStage
The Retro Synth Wavetable menu lets you create and manage custom wavetables.
Wavetable menu
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 Selected User Wavetable: Removes the loaded user wavetable.
Custom Wavetable: Loads the custom wavetable in memory. You can switch between this and a supplied wavetable.
App Wavetables pop-up menu: Load a supplied wavetable. You can switch between a supplied wavetable and the custom wavetable.
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 a custom wavetable in Retro Synth
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.
In Retro Synth in MainStage, open Table mode and choose Create Wavetable from Audiofile from the Wavetable pop-up menu.
Note: You can also drag a suitable audio file onto the Shape 1 knob.
In the File browser, choose the audio file.
Click the disclosure arrow at the lower left of the plug-in window to show the extended parameters, then choose an item from the Audio File Analysis pop-up menu.
This parameter changes the sensitivity of detection within contiguous audio sections. Choose the algorithm that works best for the audio material.
Choose “Save Wavetable as” from the Wavetable pop-up menu, then name your new wavetable in the File browser.
The new wavetable name appears in the Wavetable pop-up menu. Choose the name to load it.
