Skiff 2.6: the FM-1's screen in the Skiff Editor's Screen tab, large, on a computer or an Android tablet.

Thank you, @megasuperultrabass-lgtm and @manuhal for asking for it (#103), and @benjaminguerrer for the way to do it: a copy of Skiff that draws the screen, rather than a video of it.

Install on the FM-1: in Chrome or Edge with the Skiff installer, or download skiff-2.6.fwsc below and run python tools/fm1_install.py skiff-2.6.fwsc. Custom firmware, at your own risk; the installer page also takes the FM-1 back to the official firmware, V15 or V16.

Install on the SMK-37 Pro: read SMK37.md first, then the same installer page, or python tools/fm1_install.py skiff-2.6-smk37.fwsc.

From 2.5 or 2.5.1: nothing saved changes; your projects, sounds and patterns stay as they are. From 2.2 or older: read 2.5's notes too (every FM-1 moves to 2 CORES once, songs keep a mono delay, undo keeps 6 levels).

New

• The Screen tab in the Skiff Editor shows your FM-1's screen as large as the window allows. Tap it for full screen.
  • Connect your FM-1, open the Screen tab and press Start. The editor takes a backup of your FM-1, then restarts it, so that the copy and the unit start at the same moment. Your music is kept.
  • The picture isn't a video. A copy of Skiff runs in the page (the same build as Try Skiff); the FM-1 tells it over USB MIDI what it does, and the copy does the same and draws its own screen. So the FM-1's USB audio stays on, and there's nothing to install.
  • It works in Chrome or Edge on a computer, and in Chrome on Android with the FM-1 plugged into the tablet. iPhones and iPads can't run it: Safari has no Web MIDI.
  • What you change from the editor's other tabs shows on the copy too.
  • Under the screen, the page says how closely the copy follows: the share of frames exactly like the unit's. If it ever falls out of step, it says so; press Start to begin again.
• For developers: web/EDITOR_PROTOCOL.md describes the cast (SysEx command 83), for anyone who wants to build their own viewer.

Known

• The Screen tab works on the FM-1 only, for now. The SMK-37's keybed, pads, faders and wheels aren't part of the cast yet.
• HOME's and EDIT's waveform scopes can be a few pixels off. The FM-1's HALL reverb comes out very slightly differently from the copy's, and those scopes draw the sound.
• If the FM-1 ever has more to send than USB MIDI can carry, the copy stops and says so. Press Start again.
• Tried on our FM-1: 2.6's own package and editor in Chrome on a PC, and the same Screen tab on an Android tablet before the release build.
• #126: two FM-1s crash or hang on 2 CORES while playing, and we're looking into it. On a unit that does, MENU › SYSTEM › CPU 1 CORE is the safe setting.
• #101: GLO › CHORUS's PHASER can squeal at FEEDBACK above about 70 % while a knob moves.
• #110: a reverb's tail can still add harmonics far down.
• REMOTE's knobs are tried on the computer, not yet with a controller.
• A sound change while the music plays costs the audio one slow block (heard as nothing on our unit).
• FREE TAKE guesses between 40 and 240 BPM from the last phrase after a pause of 2.5 s, 30 s at most; 8 bars only at 1/8.
• macOS and Linux with the USB layout of 2.2 are not tried by us yet (#59).

Going back to 2.5.1

• Install skiff-2.5.1.fwsc (or the SMK package) from 2.5.1's release. Nothing saved changes between 2.5.1 and 2.6.
