How to import wavetables into Waldorf M

What Waldorf M expects

The M loads headerless 8-bit wavetable data from SD rather than a WAV container. Export 256-sample waves from Hyperwave, then convert the WAV using settings checked against your M firmware. Available manual copies and user guidance disagree about signedness, so verify a converted file before transferring a bank.

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.

Step by step

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.

If something goes wrong

Can I just copy a WAV to the M's SD card?

The M expects headerless 8-bit wavetable data. Export 256-sample frames, then convert the WAV using the settings and filename required by your firmware before placing it on SD.

Signed or unsigned 8-bit?

Available manual copies say signed, while the Waldorf user FAQ says unsigned. Confirm with a known-good file or current firmware documentation before converting.

Export settings for Waldorf M

Waldorf M has no dedicated export preset in Hyperwave.

No Hyperwave preset writes the M's raw format. Export 256-sample frames as WAV, then convert them to a headerless 8-bit file using settings checked against your M firmware.
