Drum Machine Designer Play Surface in Logic Pro for iPad
The Drum Machine Designer Play Surface in Logic Pro for iPad is an enhanced version of the Drum Pads Play Surface. It is accessible when the Drum Pads Play Surface is selected on a Drum Machine Designer main track. With the Drum Machine Designer Play Surface, you can play back and edit Drum Machine Designer kits.
Note: You can use other Play Surfaces, but the Drum Machine Designer Play Surface gives you access to features specific to Drum Machine Designer. For more information about the Drum Pads, see Intro to Play Surfaces and Use the Drum Pads Play Surface.
The Drum Machine Designer Play Surface features six columns and eight rows of playable pads in a drum grid. Drum and percussion kit pieces assigned to pads can be either synthetically generated or sample based. In fact, you can assign any supported instrument or Audio Unit Extension you have at your disposal to a pad. You can mute, solo, reorder, replace, and change the sound of each kit piece you have assigned to each pad. You can also assign each pad to different input and output notes and to different groups, and you can put kit pieces in exclusive (choke) groups.
Above the drum grid are the different function buttons you can use to switch between Play, Scroll, and Edit modes. In Edit mode, you can access and edit pad settings. You can also edit the surface settings.
Note: The Drum Machine Designer Play Surface shares many functionalities with the Drum Pads Play Surface (and the same icon in the Surface Types menu) but offers more features and flexibility.

In the Drum Machine Designer menu bar in Logic Pro, do one of the following:
Tap the Play button
or Scroll button 
, then tap a pad to trigger it.Tap the Edit button

Note: By default, the velocity is determined by the vertical tap position on the pad. To change this, see surface settings.

You can scroll the Play Surface vertically. You can also scroll horizontally, depending on the screen size and orientation of your iPad.
In Logic Pro, tap the Scroll button

Add kit pieces to unassigned drum pads

Add your own samples or audio files
You can quickly add your own samples or audio files from the Files app in Split View.
In Logic Pro, tap the Multitasking button
at the top of the screen, then tap Split View.Logic Pro moves aside, and your Home Screen appears.
Tap the Files app on your Home Screen.
The Files app appears side by side with Logic Pro.
In the Files App window, touch and hold the sample you want to import until it appears to lift off the screen slightly. To select multiple samples, touch and hold one, drag it slightly, then continue to hold it while you tap additional samples with another finger. A badge indicates the number of selected items.
In any mode in Drum Machine Designer in Logic Pro, drag the sample from the Files app to the Play Surface.
When you finish, tap the Multitasking button at the top of the Files App window, then tap Close.
Replace kit pieces using drum pads
In any mode in the Drum Machine Designer Play Surface in Logic Pro, drag a kit piece from the Browser to an assigned pad.
Replace kit pieces using subtracks
In Logic Pro, with a Drum Machine Designer track stack expanded, do one of the following:
Drag a kit piece from the Browser to the track header of a subtrack in the Drum Machine Designer track stack.
In the Browser, activate the Replace Mode button
, tap a subtrack in the Drum Machine Designer track stack to select it, then tap a kit piece in the Browser.
Reorder kit pieces
In Logic Pro, you can reorder kit pieces in the following ways:
Drag a pad to an unassigned pad in the drum grid to swap their positions.
Drag a pad between two pads in the drum grid. A vertical line is shown to indicate the target location. The pad is placed between the target pads. Adjacent (and other) pads move to accommodate the dropped pad.
Drag a pad to an assigned pad in the drum grid to swap their positions.
Note: Dragging behavior is affected by the option you chose in the Reorder Pads menu in surface settings.
Change Sounds: Changing the pad layout moves the pads and also modifies the MIDI input note of all of the pads moved. The sounds appear in a different order on the grid, and are also triggered by different keys on an external MIDI keyboard or a region on the main track.
Visual Only: Changing the pad layout moves the pads but does not modify the MIDI routing, so reordering will only have a visual effect. Moved pads appear in a different order, but assigned sounds are still played by the same MIDI notes.
Neither option modifies the MIDI output notes.
Play a kit piece chromatically and polyphonically
In the Logic Pro Tracks area, tap the disclosure arrow in the track header of a track stack, then tap a subtrack.
The Keyboard Play Surface appears. You can also choose to use a different Play Surface.
