Retro Synth’s Waveset menu lets you create and manage custom wavetables.
Waveset menu
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.
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 Table mode, choose Create Wavetable from Audiofile from the Waveset pop-up menu.
In the File browser, choose the audio file.
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.
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.
