• Shift Right 1/2 Beat: Shifts all steps in the sequence one-half beat to the right. The
number of steps that equals one-half of a beat depends on the current grid resolution.
For example, at a resolution of 1/16, a beat equals four steps, so half of one beat is two
steps; at a resolution of 1/8, a beat equals two steps, so one half of one beat is one
step, and so on.
• Shift Right 1 Beat: Shifts all steps in the sequence one beat to the right. The number
of steps that equals a beat depends on the current grid resolution. For example, at a
resolution of 1/16, a beat equals four steps; at a resolution of 1/8, a beat equals two
steps, and so on.
Create and Replace commands
• Create & Replace Randomly: Erases, then randomly creates new, steps in the sequence;
in other words, a brand new sequence is created. The number of events that are created
depends on the grid resolution.
• Create & Replace Few: Similar to Create & Replace Randomly, but a limited number
of new steps are created. The number of steps that are created depends on the grid
resolution.
• Create & Replace Some: Similar to Create & Replace Few, but more new steps are
created. The number of steps created depends on the grid resolution.
• Create & Replace Many: Similar to Create & Replace Some, but a large number of new
steps are created, effectively filling the pattern.
For example, start with an empty sequence of 32 steps at 1/16 resolution. Using Create
& Replace Few creates 4 new steps; using Create & Replace Some creates 8 new steps;
and using Create & Replace Many creates 16 new steps.
Set step length and velocity in Logic Pro Ultrabeat
The Velocity/Gate row lets you set the length (gate time) and velocity of notes in the
Trigger row. Both parameters are displayed as a single graphical bar.
• The bar height represents note velocity.
• The bar width indicates the note length (gate time).
Change the length and velocity values for each step
In Logic Pro, do either of the following:
• To change the velocity, drag the blue bar vertically.
• To change the note length (gate time), drag the blue bar horizontally.
The gate time is divided into four equal sections, making it easy to set rhythmically
accurate note lengths. For the one-shot envelope to react to gate time, it is necessary to
either turn on the Gate function in the sound itself (see Use Logic Pro Ultrabeat trigger
mode) or use envelopes in sustain mode (see Logic Pro Ultrabeat envelope parameters), in
conjunction with rhythmically useful (short) decay times.
