How to import wavetables into Pro 3
SequentialHardware synthVerified
Pro 3 from Sequential imports wavetables like this: 16 waves × 1,024 samples via the Wavetable Generator utility and SysEx.
This guide gives the exact layout Pro 3 expects, the step-by-step load, the Hyperwave export settings that match, and plain fixes for the import failures the documentation warns about.

What Pro 3 expects
User wavetables via Sequential's Wavetable Generator web utility: individual waves 16-bit, 48 kHz, ideally 1,024 samples (shorter supported, all equal length), up to 16 single-cycle waves per table; delivered to the synth as SysEx (slots 33–64).
Step by step
- Export from Hyperwave at 1,024 samples per frame, 16 frames, 16-bit, 48 kHz.
- Load the WAV into the Pro 3 Wavetable Generator utility (sequentialwaves.com) and generate the SysEx file.
- Send the SysEx to the Pro 3 over USB with a 700 ms pause between files.
If something goes wrong
- The Wavetable Generator rejected my WAV.
- Waves must all be the same length and 16-bit 48 kHz, and tables hold at most 16 waves. Export at 1,024 samples per frame, 16 frames, 16-bit, 48 kHz.
Export settings for Pro 3
Hyperwave's export dialog has a preset for Pro 3 — pick "Sequential Pro 3 — 1024 × 16" and the geometry below is what you get.
