Tactus lets you enter a passage of changing meters in seconds, then subdivide every beat exactly as the passage demands.

Tactus is a rhythmic mapping tool for musicians working with complex, changing meters and subdivisions. Tap through a bar of 5/8, into 7/16, into a plain 4/4. Then shape each beat as detailed as you want it to be.

MACRO ENTRY

Tap the meter keyboard to build your bar sequence, one tap per bar: 5/4, 7/8, 3/16, anything Enter any custom meter too, any numerator from 1 to 32 over 2, 4, 8, or 16

SUBDIVISION

Any beat can be subdivided independently, as detailed as you want it to be One beat can sit in triplets while the next sits in quintuplets Tap any pulse to cycle strong, normal, soft, silent, each with its own pitch and amplitude Group consecutive beats into a tuplet, like 3 notes over 2 beats, and subdivide a single pulse again into sub-pulses for nested rhythms

TEMPO, SHAPE & ORGANIZATION

Draw a quick but detailed tempo ramp across a range of bars for a written accelerando or ritardando Override the tempo of a single bar for metric modulation or a conductor's marking Layer conducted feel on top of the click, a visual-only pattern showing how a conductor would beat the meter, in 2, 3, 4, 5, 6, or 8 Set a bar number offset so on-screen numbers match your printed score

SYNC & SHARE

Passages live in iCloud and appear automatically on every device signed into your Apple ID Ableton Link lets Tactus start and stop in sync with another Tactus user, or any Link-enabled device, on the same network Export any passage and share it with a collaborator, so they see exactly the map you built

MADE FOR Percussionists preparing contemporary repertoire. Conductors internalizing a mixed-meter score before rehearsal. Composers, chamber musicians, and orchestral musicians working through anything a normal metronome can't handle.

Tactus is a one-time purchase. No subscription.
