How to import wavetables into E352 Cloud Terrarium / E370 Quad VCO

What E352 Cloud Terrarium / E370 Quad VCO expects

WAV banks loaded from microSD: 256 samples per wave, 16-bit, 64 wavetables per bank in an 8×8 array; WaveEdit is the official editor and the module holds 26 user banks.

Step by step

1. In Hyperwave, export with the E352 / E370 preset — 256 samples per frame, 64 frames, 16-bit — so each frame becomes one of the 64 single-cycle waves in a bank.
2. Assemble multi-bank cards in WaveEdit, Synthesis Technology's official editor, which lays out the 16-bit, 256-sample bank WAVs the module loads.
3. Copy the bank WAV to a microSD card and select it on the module.

If something goes wrong

The module refused my float WAV bank.

The module loads 16-bit WAV banks only — export with the E352 / E370 preset (256-sample frames, 16-bit) instead of the float default.

How many wavetables fit on a card?

A bank tops out at 64 wavetables, and the module holds 26 user banks.
