Inversion and Velocity
Inversion algorithms and velocity apply global changes to the progression or to the Arp.

Inversion and Weave
Inversion algorithms reshape voicings across the timeline after the chord progression is built. With help enabled, hover the control to read each algorithm's description.
Weave voices each chord near the previous chord's lowest note for smoother progressions.
For example let's say we have a progression of C Major, our first chord is C, our second chord is B and our octave is 3. The C chord will be printed as C3. With Weave enabled, the B chord will be printed as B2, because B2 is the closest B chord to the C3 chord. With Weave disabled, the B chord will be printed as B3, based on the octave we selected.
Velocity
When Velocity is on, each print rolls velocities in a selected range for arp cells or block chords. Turning it off again will keep the last roll. Shift+click the Velocity button or press Shift+V to turn Velocity off without keeping the last roll.
