Wavetables for modwave

The format modwave imports

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.

What Hyperwave exports

Every Hyperwave export is one packed wavetable WAV. Check these facts against the modwave format above — where the two disagree, the fix is almost always the frame size or a conversion step, not the sound design.

Sample format

32-bit float by default (values between -1 and +1); 16-bit WAV is a direct export option for targets that load integer banks.

Channels

1 (mono). Every frame is one single-cycle waveform.

Header sample rate

48,000 Hz by default. This is a label in the file header — for wavetable import it doesn't stretch or resample your frames. One exception: VCV Rack's Wavetable VCO reads the sample-rate field as the frame length when it's a power of two, and sample players that fall back to one-shot mode use it for pitch.

Frame layout

Frames are packed end-to-end in one data chunk, in wavetable order; the export filename records the shape as name-{samples}x{frames}.wav.

Resolution

The live table runs from 8 to 8,192 samples per frame and 8 to 1,024 frames (defaults 2,048 × 256).

Metadata

No extra metadata chunks are written — targets that read frame size from metadata have to infer it from the file itself.

Load a Hyperwave table into modwave

1. 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.
2. Import the WAV as a wavetable in the Korg Editor/Librarian.
3. Write the wavetable to the modwave so it occupies a user slot.

Common issues

• 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.
