You can also mute entire Tracks by using the similar Track Mute function.
Hardware:
1. Press the Track Mute button to enter Track Mute Mode.
2. Press Play to play the Sequence.
3. Mute a Track by pressing the corresponding pad once. The muted pad will be lit red. You can mute
multiple pads at the same time.
4. To mute a Track only at precise note intervals ("quantizing" your mutes, essentially), you can set a
musical timing value by pressing the F4 button (Time Div). Use the Data Dial or -/+ buttons to set
a musical value (e.g., 1 bar). Press F4 (Close) to close the page. Now, when you press a pad in
Track Mute Mode, the mute will occur precisely at the beginning of the following bar. This lets you
test musical combinations of patterns—the stage preliminary to building a Song structure.
