Good to know
- Nothing to save by hand: stopped and untouched for 2.5 s, GR!MM saves everything and comes back as you left it. It waits while something still sounds (SAVES WHEN SILENT).
- Six voices are shared by all four tracks; a seventh note takes the oldest. Big chords use more of them.
- On the sequencer pages PRESETS sets the tempo instead of the sound.
- SPACE's SIZE all the way up is INF: the reverb holds what is in it, like a freeze.
- The four sample slots hold URCHIN, LEAVE, NIKOLAI and M-SOFT; load your own WAVs (6.6 s each) with GR!MM's browser editor.
- Something wrong after an update? Hold OCT- while powering on: USB rescue for reinstalling.
A community cheat sheet by the hub, not by the firmware's makers: when in doubt, their manual is right.
