Chapter 76: Boom 383
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 Con-
trol 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 cre-
ated, 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 pat-
terns 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 re-
moved 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.
Using the MIDI Learn
Function on Avid Virtual
Instruments
In addition to pre-assigned MIDI controllers
(such as Sustain Pedal and Volume), you can as-
sign MIDI controllers to parameters within an
Avid Virtual Instrument plug-in for automation
or real-time control from a MIDI keyboard or
control surface. MIDI assignments are saved
with the session.
Pattern chaining can be turned on and off in
the Setup Page. When off, the above key-
board and MIDI behavior does not occur.
