Creating Boom Pattern Chains

Pattern Chains let you to create sequences of drum patterns in real time, either with the mouse and keyboard, or with MIDI notes.

To create a pattern chain with the mouse and keyboard

1 Press Play on Boom’s transport.

2 Switch Boom into Pattern Select mode.

3 Click the Event switch that corresponds with the pattern you want to start the chain with.

4 Hold Control on the computer keyboard and click the Event switches that correspond with each pattern you want to add to the chain.

5 Boom will play the patterns you’ve chosen in the order they were added to the chain.

6 To remove a pattern from the chain, hold Control and click its Event switch.

7 To go back to playing patterns individually, click any Event switch without holding down Control.

To create a pattern chain with MIDI notes

1 Press and hold a MIDI note between C3 and D3 on your MIDI controller, triggering a pattern.

2 Press and hold a second note in that range along with the first. A Pattern Chain will be created, and Boom will alternate between playing the first pattern you chose, and the second.

3 Press and hold another note, and it will be added to the chain. Boom will play all three patterns in sequence. If you hold down more notes, their patterns will be added to the chain.

4 If you let go of a note, its pattern will be removed from the chain. If you let go of all but one note, the chain will stop, and Boom will go back to playing one pattern repeatedly.

This MIDI data can be recorded and edited using the MIDI sequencer in Pro Tools, let you more easily create sequences of drum patterns.

If you do not have a MIDI controller, you can use the Pencil tool in Pro Tools to create a sequence of MIDI notes that can trigger Pattern Chains.

Pattern chaining can be turned on and off in the Setup Page. When off, the above keyboard and MIDI behavior does not occur.
