Playing with Patterns in Boom
Now that you’ve started creating patterns, let’s take a look at how to switch between and create variations of them.
To switch between patterns on-the-fly:
1 Press Play on Boom’s transport.
2 Set the Edit Mode switch to Pattern Select mode.
3 Click the Event switch marked 2. A different pattern will start to play, and its notes will appear in the Matrix display.
4 Press Event switch 1, and you’ll see and hear your original pattern return. Make a copy of it, so that you can create a variation of the pattern.
To copy a pattern:
1 Click the Copy button above the Matrix display. Event switch 1 lights up red, and Event switches 2–16 blink, indicating that they are available to receive a copy of the selected pattern.
2 Click Event switch 2. The Event Bar returns to its normal state, and pattern 1 will be copied to pattern 2.
3 If you decide before doing so that you don’t want to copy the pattern after all, just press any other button or move any other control besides the Event switches, and the Copy action will be cancelled.
4 Press Event switch 2, then set the Edit Mode switch back to Pattern Edit mode. You’ll see that you now have an identical copy of pattern 1 to work with. Make a simple edit to the pattern, by adding a rhythmic fill.
To create a simple fill:
1 Select Snare Drum, and toggle Event switches 13–16 to on. This will give you a simple 4-note snare roll at the end of the pattern.
2 Try switching between patterns 1 and 2 to hear the new pattern and the fill you’ve added.
