Select G1T1 and go to the LENGTH page. Set the length of the track to 16 (so the display will
show 16/128), then select G1T2, and set the length to 8 (so that the display will show 8/128).
Now you have two tracks that are of different length. Select G1T1 and press EDIT. Track
initialisation has probably entered some notes in the track which are not wanted, so press
CLEAR to get rid of them.
Punch in some notes with the GP buttons under the displays. For the first track you, for
example, could punch in every other button, i.e. steps 1, 3, 5, 7, 9, 11, 13 and 15. Each GP
button press will produce the note C-3, and if you press again, you can delete it. Let's leave
the notes there for now, though, so press a GP button for another time if you deleted any
notes.
Next, select G1T2, CLEAR the track and punch in the notes as with the first track, but then
use the GP knobs under the notes to adjust the value of each note so that the first two
become E-3, the next two become G-3, and the four last ones become G-2.
Remember that the second track is only 8 steps long. If you punched in the notes on the right
LCD as well (like you did with G1T1), it does no harm, but they will not get played unless the
track length is set to 16 steps. However, let's keep the track length at 8 for the purposes of
this demonstration, and despite the shortened length, let's keep the notes on the right LCD.
Everything should now be ready. Press PLAY on the front panel to start the sequencer. If you
still have G1T2 selected, you will see a red indicator LED running from left to right. It will go
up to the eighth step and then start again from the first step. Now select G1T1 (while the
sequencer is still running), and you will see how the red cursor is running all the way up to
step 16, and then starts from the beginning. Try turning one of the GP knobs to change one
note one up or down on each track. You can also press MENU + LENGTH while the sequencer
is playing and use the quick select buttons on the right display to change the length of a track
live.
You can change the length with the knobs as well, but there you'll run a higher risk of making
the tracks go out of sync. If this happens, you can always stop the sequencer and hit PLAY
again.
The idea of this was to demonstrate in a concrete way that the tracks are running
independently of each other, even if they are within the same pattern. You could press STOP,
change G1T1's length to some strange value like 11, press PLAY again, and each track would
run its length and then wrap back to the start, regardless of where the other track is going.

2.3.1. Tempo
Even though by default the tracks are running independently of each other, they share the same
tempo for reference. This can be set by pressing MENU + BPM. The BPM (beats per minute) setting
