How to import wavetables into modwave
KorgHardware synthVerified
modwave from Korg imports wavetables like this: loads Serum-style tables via the Editor/Librarian.
This guide gives the exact layout modwave expects, the step-by-step load, the Hyperwave export settings that match, and plain fixes for the import failures the documentation warns about.

What modwave expects
The Editor/Librarian imports packed WAV in two formats: 32-bit float with 2,048-sample waves (the Serum-style layout) or 16-bit with 256-sample waves — up to 64 waves per file in either mode. Longer float tables are assumed to be generated crossfades and thinned to 64. The software modwave native shares both formats, with its own Librarian-page 'Import WAV As Wavetable' route.
Step by step
- Export from Hyperwave as a packed mono IEEE-float WAV at 2,048 samples per frame — the Serum-style layout the Editor/Librarian reads directly.
- Import the WAV as a wavetable in the Korg Editor/Librarian.
- Write the wavetable to the modwave so it occupies a user slot.
If something goes wrong
- My table lost waves on import to the modwave.
- The Editor/Librarian keeps at most 64 waves per table and assumes longer float tables are generated crossfades, thinning them to 64. Export 64 frames or fewer to keep every frame you drew.
Export settings for modwave
Hyperwave's export dialog has 2 presets for modwave — pick the one matching the import mode you use:
- Korg modwave — 2048 × 64
- 2,048 samples per frame × 64 frames · 32-bit float · 48 kHz
- Korg modwave (16-bit) — 256 × 64
- 256 samples per frame × 64 frames · 16-bit PCM · 48 kHz
