Use Step Sequencer with Drum Machine Designer in Logic Pro for Mac
Step Sequencer is especially suited to creating drum patterns using Drum Machine Designer patches. When you create a new pattern region on a track with a Drum Machine Designer patch, note rows show names and icons matching the kit pieces in the patch (rather than MIDI note names), and the Row Assignment pop-up menu shows the kit piece names rather than MIDI note names.
When using Step Sequencer with a Drum Machine Designer patch, changing the note or octave values for steps transposes the pad kit piece rather than changing the drum sound, as it does for Drum Kit Designer or other drum kit software instruments. Unlike with other types of instruments, the row name retains the name of the kit piece rather than changing to Melodic.
You can separate a pattern region using a Drum Machine Designer patch into multiple pattern regions, so that each row is separated into its own one-row pattern region. The separated regions are placed on the subtracks of the Drum Machine Designer track stack matching the originating kit piece rows. This can be useful when you want to work with the resulting rows as separate regions. This function is similar to the MIDI Separate by Note Pitch function.
Separate a Drum Machine Designer pattern region per kit piece
In the Logic Pro Tracks area, select the pattern region.
Do one of the following:
Choose Edit > Convert > Separate by Kit Piece in the control bar.
Choose Edit > Convert > Separate by Kit Piece in the Tracks Area menu bar.
Control-click the region, then choose Convert > Separate Pattern Region by Kit Piece from the shortcut menu.
To view and edit the new pattern region for each row, click the disclosure arrow to open the track stack.
