Time Signature

The Time signature menu sits in the sequencer transport between Zoom and Measures. Use 4/4 for the default feel, 3/4 for three quarter-note beats per measure, 6/8 for six eighth-note pulses, or 7/8 for an uneven seven-pulse measure.

Changing the signature changes how each visual measure is divided. The timeline and arrangement grid show measure starts plus the main units inside the measure: three units in 3/4, six eighth-note units in 6/8, and seven eighth-note units in 7/8. The playhead, loop range, and exclusion range follow the same divisions.

BPM still describes the quarter-note tempo. Existing regions, notes, automation, pitch bend, and imported older workflows are not retimed when you choose a new signature; older workflows open in 4/4 unless they already saved another signature.

Regions snap to the active musical grid when you move them or resize either edge. Trimming the left edge keeps earlier notes and automation hidden rather than deleted, so extending the region left again can bring that material back.

Inside a region, the note editor, automation editor, and pitch bend lane draw their grid from the active signature. Note quantization still uses the Quantize precision menu, so 1/8, 1/16, 1/32, and 1/64 remain note-value choices while the measure markers adapt to signatures like 3/4, 6/8, and 7/8.

The metronome accents the first main unit of every measure and plays weaker clicks on the remaining main units. That means four quarter-note clicks in 4/4, three in 3/4, six eighth-note clicks in 6/8, and seven eighth-note clicks in 7/8.

Blank Drum Machine pages take their default step length from the current signature. A new blank page is 16 steps in 4/4, 12 steps in 3/4 or 6/8, and 14 steps in 7/8, while existing non-empty drum patterns keep the length they already had.

BPM-synced nodes distinguish note-value divisions from measure-value divisions. Existing choices such as 1/1 still mean a whole note of four quarter-note beats, while explicit choices such as 1/2 bar, 1 bar, and 2 bars follow the selected time signature. This first version uses one global signature for the whole song; it does not support mid-song signature changes or different signatures per track.
