Wavetables for Serum
Xfer RecordsSoftware synthVerified
What a Serum wavetable import expects, and how a Hyperwave export maps onto it.
The format Serum imports
Packed mono WAV, 2,048 samples per frame, up to 256 frames (~11.9 s at 44.1 kHz); Serum's own wavetable exports are 44.1 kHz mono in 16- or 32-bit, and the sample-rate header doesn't affect frame layout. An optional 'clm ' metadata chunk records frame size and morph mode.
What Hyperwave exports
Every Hyperwave export is one packed wavetable WAV. Check these facts against the Serum 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 Serum
- Export the table from Hyperwave as a packed mono WAV — 2,048 samples per frame and up to 256 frames is the layout Serum's factory tables use.
- Drag the WAV onto Serum's oscillator display to load it immediately.
- Or copy the WAV into the Tables folder in your Serum presets directory so it appears in the wavetable menu.
Common issues
- Serum assumes 2,048 samples per frame; the optional 'clm ' metadata chunk records frame size and morph mode, but Serum is documented to assume 2,048 regardless — export at 2,048.
Design the table once in Hyperwave's node graph, export the packed WAV, and load it into Serum with the steps above.
