Wavetables for Blofeld

The format Blofeld imports

User wavetables reach the synth through Waldorf's official tools: the Blofeld plugin loads prepared SysEx/MIDI wavetables, or imports audio WAV with samples-per-wave selectable from 32 to 4,096 (the classic on-device table is 64 waves × 128 samples; the plugin thins larger wave counts on import).

What Hyperwave exports

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

1. Export from Hyperwave as a packed mono WAV, picking a samples-per-wave the Waldorf tools accept (32 to 4,096; 2,048 is Hyperwave's default).
2. Import the WAV in the Blofeld plugin — Waldorf's official editor — which converts the audio, or load a ready-made SysEx wavetable file (a special MIDI-dump file some tools export) if you have one.
3. Send the finished wavetable from the plugin over USB or MIDI into one of the Blofeld's user wavetable slots.

Common issues

• The plugin's 'Full Wavetable Range' import keeps only every fourth wave once a table passes 64 waves — export 64 frames or fewer to keep every wave you drew.
