Use side controls with the Play Surfaces in Logic Pro for iPad

The side controls consist of pitchbend, modulation, note repeat, and velocity range. You can use these to change the character of the sound when using a Play Surface. The controls for pitchbend and modulation and those for note repeat are mutually exclusive, so turning on one set of controls turns off the other. When you open the side controls, they appear on the left side of the Play Surface.

Turn on the side controls

In the Play Surface menu bar, tap the Side Controls button .
The side controls appear to the left of the Play Surface. By default, the pitch and modulation controls are active and the velocity range control is visible.

Use note repeat in the side controls

In the Play Surface menu bar, tap the More button , tap View Options, then tap Note Repeat.
Controls for note repeat appear to the left of the Play Surface.
Touch a bar/beat value in the Rate slider to set the repeat rate.
Play notes in the Play Surface.
Drag the Gate slider up or down to set the length of the repeated note.

Change the values for the note repeat controls

In the Play Surface menu bar, tap the More button , then tap Configuration.
Under Note Repeat, do the following:
- Change the gate range: Tap the Gate Range fields and set the Low or High values.
- Change the note repeat values: Tap a value for the corresponding slot and choose a bar/beat value.

Use the mod wheel to send MIDI expression control change

In the Play Surface menu bar, tap the More button , tap Configuration, then tap Expression (CC# 11) in the Mod Wheel pop-up menu.

Change the velocity mode

The velocity mode determines how the velocity values for MIDI notes are created. You can set the velocity to a fixed value or set it to be determined by how hard you tap the Play Surface. The velocity for drum pads can also be determined by the vertical tap position on the drum pad.

In the Play Surface menu bar, tap the More button , tap Surface Settings, then choose one of the following values for Velocity Mode:
- Fixed: Forces all notes to the same velocity set by the velocity value.
- Dynamic: The velocity value is determined by how hard you tap the drum pads. Minimum and maximum velocity are determined by the Velocity Range values.
- Y-Position: The velocity value is determined by the vertical tap position on the drum pad. Minimum and maximum velocity are determined by the Velocity Range values.

You can use the Velocity controller in the Play Surface to change the velocity range or the fixed velocity value.

Change the velocity range

Depending on the velocity mode setting, you can change velocity range or set a fixed velocity value.

In the Play Surface menu bar, tap the More button , tap View Options, then tap Velocity.
Tap the Side Controls button .
The velocity range control appears to the left of the Play Surface.
If the velocity mode is set to Dynamic or Y-Position, do one of the following:
- Drag the top slider of the velocity range control up to change the maximum velocity value.
- Drag the bottom slider of the velocity range control down to change the minimum velocity value.
- Touch the velocity range control between the sliders and drag up or down to move the velocity range.
If the velocity mode is set to Fixed, drag the velocity slider up or down to set the velocity value.
