Arpeggiator MIDI plug-in Grid mode in Logic Pro for iPad

The Arpeggiator MIDI plug-in operates in two distinct functional modes: Live and Grid. The modes are mutually exclusive, so turning on one turns off the other. It also provides a unique Live Capture to Grid facility.

When Grid mode is active, it controls the arpeggio velocity, cycle length, step length, rests, ties, and chords. All live input of available grid parameters, such as velocities, is ignored.

When in the default Live mode, the arpeggio performance is controlled by your input. For example, the velocities of arpeggiated notes are determined by the way you played them. Any existing grid values are retained but are disabled until you return to Grid mode.

Note: When you capture a live performance, grid values are not retained.

In Live mode, you can add rests, ties, and chords in real time by tapping the onscreen buttons or by using equivalent MIDI keyboard remote keys. See Assign Arpeggiator controllers.

The grid consists of 16 steps. Each step controls the step velocity as well as its length, rest, tie, and chord status. In addition, a cycle length can be set. The current grid pattern is automatically saved with the project or concert. You can also save and load your own or factory grid patterns. The Arpeggiator plug-in assigns incremental position identification numbers in the order they were received, regardless of the initially selected note order preset. These position identification numbers are used to “lock” an event, such as a note, a rest, or a tie to a particular step.

Grid mode parameters

On/Off button: Turn on Grid mode. The grid has 16 steps. Each step controls velocity, length, rest, tie, and chord status.
Capture button: Tap to capture the current arpeggiator settings as a grid pattern. This appears as the Custom entry in the Patterns pop-up menu.
Patterns pop-up menu: Choose a menu item to load user grid patterns or to load a factory grid pattern.
- Custom: This menu item is shown automatically when any pattern changes have been made. It can be considered the “current state” pattern preset.
- App Patterns submenu: Tap to choose a factory pattern preset.
Next/Previous Pattern buttons: Choose the next or previous pattern preset.
Length knob: Change the grid length.
Note: The (grid) Length value is independent from the Cycle Length parameter (which sets the length of the arpeggiated note pattern) described in the options parameters. The grid length cycles independently of the effective note pattern. This prevents disruptions to the perceived rhythmic pattern created by the grid, which can occur when you change the arpeggio length.
