How to import wavetables into MicroFreak
ArturiaHardware synthVerified
MicroFreak from Arturia imports wavetables like this: mIDI Control Center imports WAV/AIFF into a 16-slot wavetable bank (firmware 4.0+).
This guide gives the exact layout MicroFreak expects, the step-by-step load, the Hyperwave export settings that match, and plain fixes for the import failures the documentation warns about.

What MicroFreak expects
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).
Step by step
- Export from Hyperwave as a packed mono WAV at 2,048 samples per frame, up to 32 frames.
- In the Arturia MIDI Control Center, open the Wavetables tab and import or drag the WAV into a slot.
- Send the bank to the MicroFreak and select the WaveUser oscillator.
If something goes wrong
- Can the MicroFreak load tables longer than 32 frames?
- No — tables longer than 32 frames exceed the documented bank geometry. Export at 2,048 samples per frame, up to 32 frames.
