Wavetables for Waldorf M

The format Waldorf M imports

The M imports headerless 8-bit wavetable files from SD, with 256 samples per wave. Published manual copies and user guidance disagree on signedness, and the documented wave count and slot numbering need a current firmware check.

What Hyperwave exports

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

1. Export a table from Hyperwave at 256 samples per frame.
2. Convert the WAV to headerless 8-bit data using settings confirmed for your M firmware. Check signedness, wave count, and filename against a known-good file or current device instructions.
3. Copy the converted file to SD and use the M's Import User WT function.

Common issues

• The M imports headerless 8-bit wavetable data from SD rather than a WAV container, so Hyperwave's WAV needs conversion.
• Available M manual copies and the Waldorf user FAQ disagree on signedness; check the current firmware documentation or test a known-good file before converting a bank.
