7.2 Shorten a pattern
To make a 64-step pattern shorter uses a slightly different procedure. Let’s say you want
the pattern to be 48 steps long instead:
• Hold the Last Step button until the process is complete.
• Press the << button to select Step Group 3. The “48” LED will light.
• Still holding the Last Step button, press Step button 16. It will turn blue, which
means the pattern is now 48 steps long.
• If you want the pattern to be even shorter, start over and press the << button
until the proper Step Group is selected.
To select a pattern length other than a multiple of 16, use the Last Step button and
press the appropriate Step button to define the final step in the pattern. This process is
described in section 5.2.9.
7.3 Polyrhythm mode
This feature is as interesting as it is unusual. And it has the potential to unleash creative
explorations you might never have considered otherwise.
7.3.1 What is Polyrhythm mode?
Usually a drum machine pattern will operate within a single time signature, such as 4/4
or 12/8. For example, with a single measure of 4/4 there are sixteen 16
th
notes, and if a
drum only plays on the downbeat it must wait another 15 steps before it plays again.
But with the DrumBrute’s polyrhythm feature you can specify a different time signature
for each instrument track! This could mean you’d have 16 loops of different lengths all
happening at the same time.
7.3.2 What it does
Here’s an example: What if you wanted a pattern with this mixture of time signatures:
Instrument
Kick 1
Kick 2
Snare
Clap
Rim
Time signature
3/16
1/4
5/16
3/8
4/4
The Rim track is the longest, so we’ll use that as the timing reference for our discussion.
Here’s how those tracks would look in the MIDI Control Center:
