Wavetables for Deluge

The format Deluge imports

Official firmware 4.0+ (April 2022) added wavetable synthesis: WAV/AIFF files (16/24-bit 44.1 kHz preferred, up to 32-bit 96 kHz) loaded from SD card; wavetable-formatted files are recognized automatically and assigned oscillator TYPE 'WAVEtable'. Files under 20 ms are treated as single-cycle.

What Hyperwave exports

Every Hyperwave export is one packed wavetable WAV. Check these facts against the Deluge 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 Deluge

1. Export from Hyperwave as a packed mono WAV.
2. Copy it to the Deluge's SD card.
3. Load it as a synth oscillator — the Deluge recognizes the wavetable format and sets the oscillator type.
