Installation
TL;DR: Felucca 1.6 — your own UI colours from the web editor, a SEQ roll that follows the play position, conditional steps (1:2 … 4:4, FILL), EUCLID, DOUBLE / HALF, a MIDI channel per track, PHASE FOLD, three more drum kits and humanize in the MOD matrix, on top of 1.5.1's SEQ > DETAIL, MIDI Program Change, dotted delay times and REV / ECHO THROW, and 1.5's INSERT effects and MIDI LEARN. Connect your FM-1 to a computer by USB, open the web installer in Chrome or Edge, and press Install; no extra hardware is needed. Installing is at your own risk: M-VAVE's updater or the installer's Return to official V15 takes you back. Coming from 1.1.5.x? Read ⚠ Coming from 1.1.5 first: projects saved by 1.4 or later do not open on 1.1.5.x. Going back from 1.6 to 1.5 or 1.5.1? Read ⚠ New in 1.6 first: a project with conditional steps does not open there. Going back from 1.5.x to 1.4.1? Read ⚠ New in 1.5 first: projects saved by 1.5 do not open on 1.2 to 1.4.1. Want to look around first? Try it in your browser, no FM-1 needed.
