Wavetables for MicroFreak

The format MicroFreak imports

Firmware 4.0+ WaveUser oscillator loads user wavetables via the MIDI Control Center — MFWZ, WAV, or AIFF — into a bank of 16 wavetables, with bidirectional drag-and-drop. Per press coverage, tables are 32 cycles × 2,048 samples (converted to 256 samples per cycle in the MIDI Control Center, not on the device).

What Hyperwave exports

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

1. Export from Hyperwave as a packed mono WAV at 2,048 samples per frame, up to 32 frames.
2. In the Arturia MIDI Control Center, open the Wavetables tab and import or drag the WAV into a slot.
3. Send the bank to the MicroFreak and select the WaveUser oscillator.

Common issues

• Tables longer than 32 frames exceed the documented bank geometry.
