Industrial Music ElectronicsEurorack / modularVerified
Piston Honda MK3 from Industrial Music Electronics imports wavetables like this: eight 16-bit WAV files on microSD.
Every fact is verified against Industrial Music Electronics's own documentation or source code — sources at the end of the page, checked 2026-08-16.
What Piston Honda MK3 expects
microSD load of eight mono 16-bit WAV files named 1.wav through 8.wav — the eight files are eight independent Z-axis banks, each holding an 8×8 X/Y table of 64 waves × 256 samples (together the 8×8×8 = 512-waveform cube). All eight files must be present or the load fails.
Step by step
- In Hyperwave, export with the Piston Honda MK3 preset — 256 samples per frame, up to 64 frames, 16-bit — one export per Z-axis bank.
- Name the eight exported files 1.wav through 8.wav, padding any unused Z slots with the IME factory waveset.
- Copy the eight files to microSD and load them to fill the 512-waveform cube in one operation.
If something goes wrong
- The module refused my float WAV files.
- The module loads mono 16-bit WAV files — export with the Piston Honda MK3 preset (256-sample frames, 16-bit) instead of the float default.
- My long table won't fit in one file.
- The eight files are eight independent Z-axis banks, each an 8×8 X/Y table of 64 waves — a table can't exceed 64 waves per file. Export eight separate 64-wave tables (one Hyperwave export each) and pad unused Z slots with the IME factory waveset; the load fails unless all eight files are present.
