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
- 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.
- Assemble multi-bank cards in WaveEdit, Synthesis Technology's official editor, which lays out the 16-bit, 256-sample bank WAVs the module loads.
- 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.
