Views

SHIFT+RECORD SETTING steps through five views of the grid. In the zoomed view, REMAIN+turn VALUE zooms out. SHIFT+turn VALUE goes to the next bar, or the next beat in the zoomed view. While a pattern plays the grid follows it from bar to bar; SHIFT+HOLD keeps it on the bar you picked, and again follows.

Piano roll

Press VALUE to open the selected track as a piano roll. Hold a step's pad and press another pad as a key: pad 5 is the sound's own pitch, pads 1 to 4 go down, pads 6 to 16 go up. Press VALUE again to close it.

Recording

REC once rehearses: the pads play and nothing is recorded. REC again records, and EXIT stops. HOLD turns the pads into normal pads to play along. The record mode, SINGLE, MULTI or CHROMATIC, is in the pattern panel and on a shortcut. SHIFT+pad 9 sets the metronome: ON clicks while you rehearse and record, RECPLAY whenever the pattern plays, OFF.

PATTERN EDIT shows eight tools. Turn VALUE to pick one and press it to open it, then turn to choose and press to apply; EXIT leaves it as it was. Tap a track's pad first to work on that track only. SHIFT+PATTERN EDIT opens the settings for new notes.

Mixer

In the track panel, turn VALUE to MIXER and press it. Turn VALUE to select a track.

CTRL knobs VALUE

CTRL 1 pan, CTRL 2 bus, CTRL 3 level.

Help

Hold SHIFT for three seconds. Then press any button, pad or knob to see what it does; nothing plays or changes. EXIT leaves help.

The full list. Most of it is also in the menus: press RECORD SETTING or PATTERN EDIT and turn VALUE. On the box, hold SHIFT for three seconds and press any button to see what it does.
