8.4.2. Polyphonic arpeggios
The Matrix Arpeggiator is polyphonic. Here are some things to know about that:
• Multiple cells can be enabled in each column.
• A long press on a cell will clear the others in the same column.
• Pressing and holding two cells from different columns draws a "monophonic"
line between the two cells.
8.4.3. Approach notes
In Matrix Arpeggiator mode "chromatic approach" notes can be assigned:
• Lower approach note: If you turn the Amount knob counter-clockwise while
pressing a button in the voice assign section, the button turns red instead of blue.
This means the note is played one half step below the held note.
• Upper approach note: If you turn the Amount knob clockwise while pressing a
button in the voice assign section, the button turns purple instead of blue. This
means the note is played one half step above the held note.
• To restore the original pitch press the voice assign button twice. It turns blue
again.

♪: If you hold the Matrix button for 1+ seconds before turning the Amount knob, the other cells in the
same column will be cleared. You'll need to re-enable them if you want that step to be polyphonic.
8.4.4. Play Mode: Matrix Arp
Hold [Play Mode] and use [Assign 1-4] to select an option. These set the playback direction
for the pattern.
• Forward plays the pattern from the first step to the last, then starts at the
beginning again.
• Pendulum plays the pattern forward and then backward, repeating the first and
last steps.
• Random can trigger any step inside the sequence length, even steps that contain
no data.
• Walk moves according to probability, not chance. On each step there is a 50%
chance that the next step will be the one to the right, a 25% chance the same
step will repeat, and 25% chance that the previous step will play.
Press [Play Mode] repeatedly to step through the various options.
