3.1.1. Gate
Gate is the basic trigger, without which other layers (whether trigger or parameter) cannot express
themselves. Gate controls whether the data in the step is going to be played or not. If gate is 'on', the
contents of the step's layers will be played, and if it's 'off', it will be treated as an empty step, even if
there is data in the other layers of the step.
You can verify this by pressing & holding EDIT, which brings up a menu where you can choose
the type of EDIT view you want. Choose 'Trigger View'. The left display shows eight trigger
layers, and the right display shows the first eight parameter layers. (If you need to see the
rest of the parameter layers, you can choose 'Layer View', which shows all available
parameter layers.)
If you select G1T1 and use GPK1 to view Step 1, you can see that Gate is 'on' (*), and all the
other triggers are 'off' (o). As to the parameter layers, you can see that note, velocity and
length layers have something in them. Now use GPK1 to select Step 2. All the information in
the steps stays the same, only the gate flag is turned 'off' (o). If you switch back to step view
(press & hold EDIT), you can't see anything on the display for step 2, because gate is 'off'. But
if you press GPB2, you will create a C-3. Where did that come from? It was in the step all the
time, your button press just turned the gate on, and made the information in the step
“visible”.
3.1.2. Accent
If the Accent trigger is 'on' (*), it simply means that the step will be played at maximum velocity
(127), i.e. “as loud as” it can be played. Velocity values simulate the force with which you strike a
piano key: the higher the value, the “harder” the note is played. However, synthesizers often allow
many other variables to be controlled with the velocity value, so it depends on your synth's settings
what velocity actually does.
3.1.3. Roll
If the Roll trigger is 'on', it means the note in the step will be played two times in quick succession
within that step (a kind of flam). This allows only very simple rolls. For more detailed control over the
roll in a parameter layer, see section 3.2.4.
Note that the Roll trigger won't work if the Sustain setting on MODE page is on.
