TBOSS 1.7: step sequencer, MIDI effects, Bass, Program Change, even pads

Install: open the installer in Chrome or Edge; it offers this version. Step 2 keeps your settings, presets, scales, progressions, chord sets, buttons and step pattern when updating. Unplug the power adapter too before entering update mode, if one is plugged in.

TBOSS 1.7 is the next release after 1.5 (it includes the features of 1.6, which was never announced). Every new option is off, or plays as before, until you change it. From this version on, releases are named by their major and minor number: the board's About screen says 1.7.

New since 1.5

• A deeper step sequencer: each step gets its own velocity, gate, tie, chance, ratchet (2–8 strikes) and condition (1:2 … 4:4, first time round, every time but the first); hold steps, ▲/▼ choose, ◀/▶ change. Lanes run forward, reverse, ping-pong or random, and Euclid fills a lane with evenly spread hits (Settings → Sequence).
• Four MIDI effects: Harmony (diatonic harmony on the melody pads, always in the scale), Echo (a MIDI delay locked to the tempo or your DAW's clock), Mono (one melody note at a time, newest wins, legato) and Chance (the arpeggiator and note repeat skip steps at random).
• Bass layout (Settings → Layout → Layout → Bass): the original's promised bass mode. Each scale note sits on two pads side by side for fast two-finger bass lines; every hit strikes the note again.
• Program Change both ways (Settings → MIDI): each half sends its synth's sound with every preset (Chord prog, Melody prog), also just after connecting and when your DAW starts; a DAW can load presets 1–8 by sending programs 1–8 (Program in).
• Pads that play evenly on any board (Settings → Pads): Trigger, Release and Full count from each pad's own resting level, a firm press no longer sets off its neighbors, and Unstick ends a note whose pad stays down by itself. Rescan pads measures every pad again. Your pad settings are converted when you update.
• Smaller additions: Spread of Chord opens the whole chord (Settings → Chords → Spread of), held chord shapes (Add 7th …) change a running arpeggio at once, the pedal works as Sustain out of the box, and EXT shows on the play screen while a DAW's clock comes in.

Walk-throughs in the manual: what's new in 1.7 · in 1.6 · Step options · Harmony, echo and mono · Bass · Program Change · Pad sensitivity.

Going back to an older version keeps everything that version has: 1.5 plays step patterns forward without the step options, the effects off and the Bass layout as Scale.

Known limit: an echo that comes while you still hold its note is not heard.

Please check: the pedal's Target and its other modes, live notes following MIDI in, progressions started by a DAW, scale lock, and DAWs other than Ableton Live are not yet confirmed on a board. A test report is very welcome, even if everything worked.
