How to resize Wavetable

3/2/2020

This section introduces how to convert your own wavetable created with the plug-in into a wavetable for hardware synths. (The reverse method is also available.) As an example, I will show you how to convert a wavetable for Ableton to a wavetable for WaveEdit. It can be applied to other synthesizers.

Ableton Wavetable(A 1024 sample long single cycle waveform.)
Synthesis Technology WaveEdit(A 256 sample long single cycle waveform.)

(Example)Ableton Wavetable→WaveEdit

Things to prepare

Ableton Wavetable →WaveEdit

Audacity(method1)
Start Octachainer to connect the created waveforms

Audacity(method2)

WaveEdit→ Ableon Wavetable

Apply wavetable effects with WaveEdit
Convert to Ableton wavetable again with Audacity

Audacity(method1)

Select 64 sequential waveforms from the downloaded Wavetable SCW folder and import them into Audacity.
Press Crrl + A to select all waveforms.
Select Speed change from effect.
Change new length to 256 samples

Export mulitiple(Turn off metadata editor from preferences)

Start Octachainer to connect the created waveforms

Select Evenly spaced grid.
Press Add to insert the created waveforms.
Select Mono from Channels.

Audacity(method2)

Import wavetables into Audacity
Set the sample selection to [Start and Length of Selection] and set the unit to sample.
Select a sample and set the length of the selected range to 65536 samples (= 1024 × 64).
Press CtrL + T to trim the wavetable.
Select Speed change from the effect and quadruple the speed doubling.
Save.

Wavetable for WaveEdit is now complete.

WaveEdit

Select Open Bank from File and import the created wavetable.
Select Effect Editor and add effects to the wavetable.
Press Bake to reflect the effect as an audio file.
Select Save Bank from File and save.

Convert for Ableton with Audacity

Import the wavetable created by WaveEdit and select Change speed
Previously it was 4x speed from 1024 samples to 256 samples, so now reverse to 0.25x speed from 256 samples to 1024 samples.
Export as Wav file.

Import to Ableton Wavetable

The waveform of 1024 samples can be expressed up to the 512th overtone, and 256 samples can be expressed up to the 128th overtone. The waveform converted from 1024 samples to 256 samples can only be expressed up to the 128th harmonic even if it is restored to 1024 samples again.
