F3 toggles Mixer Mode, where two decks each hold a patch.
Mix modes are described in Mixer Controls.
Mixer Mode carries its own modulation, separate from the editing view’s:
one LFO bank, one Envelope bank, and one Time bank, all shared across both
decks, plus a single Mixer-wide undo/redo stack. Macros are the one
deck-scoped source, four per deck, named A1 to A4 and B1 to B4.
Each deck also loads a patch, which brings that patch’s own modulators with
it. Right-clicking any mixer control offers the same Edit Modulation window
as a patch parameter, using the Mixer’s own sources, and MIDI Learn. A dot
marks each control that is being modulated.
H hides or shows the controls. Escape first restores hidden controls;
if they are already visible, it exits Mixer Mode.
A slim strip along the top keeps the REC and camera pill, the recording
timer and the recording settings within reach, and Ctrl+Alt+R
(Cmd+Option+R on macOS) starts or
stops a recording from the keyboard. While H hides the controls, a small
red lamp in the corner shows that a recording is running.
