Wavetables for Pro 3

The format Pro 3 imports

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).

What Hyperwave exports

Every Hyperwave export is one packed wavetable WAV. Check these facts against the Pro 3 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). Single-table and collection exports can render 8–16,384 samples per frame and 1–256 frames.

Metadata

Hyperwave writes no extra wavetable metadata chunks. Importers use the audio layout, their own defaults, or settings you choose to interpret the frames.

Load a Hyperwave table into Pro 3

1. Export from Hyperwave at 1,024 samples per frame, 16 frames, 16-bit, 48 kHz.
2. Load the WAV into the Pro 3 Wavetable Generator utility (sequentialwaves.com) and generate the SysEx file.
3. Send the SysEx to the Pro 3 over USB with a 700 ms pause between files.

Common issues

• Waves must all be the same length and 16-bit 48 kHz; tables hold at most 16 waves.
