Using Boom
Boom is a virtual drum machine featuring a broad range of percussion
sounds. The Boom user interface provides a simple, drum-machine-style
pattern sequencer. Boom comes with 10 drum kits inspired by classic
electronic drum machines.
To use the Boom plug-in, add the plug-in to an Instrument track as described
in the “Placing a Virtual Instrument on an Instrument Track” section earlier in
this lesson. The Boom user interface will open, displaying the pattern for the
<factory default> preset.

The Matrix Display on the left side of the plug-in window presents a visual
overview of the current pattern in Boom’s sequencer. The Matrix provides a
way to work with patterns and to keep track of the step that Boom is playing
at any given time. Each lit LED in the sequencer corresponds to an instrument
that is sequenced to play at that step. The brighter the LED, the higher the
velocity of the instrument trigger. You can click each LED directly to add a
note on that step. Successive clicks toggle through velocity levels or toggle
the note on/off.
