Note that “glide” here has a different meaning than in the trigger layer glide (section 3.1.4.). Here
glide means simply that the same note is extended over several steps, which has no effect on pitch;
in trigger layer glide, however, the whole idea is to glide from one note to another, different note, i.e.
from one pitch to another.
The setting Sustain on the MODE page is good to keep in mind when setting up a track to play long
notes. Sustain holds each note/chord until another one is played, and this spares you the trouble of
having to set the gate length of each individual note/chord.
When editing gate length per step, it is also good to keep in mind the ALL button function, which
allows you to edit the values several steps with one knob (see section 4.2.3.).
3.2.4. Roll and Roll2
Roll controls the number of hits per step and their intensity curve, whereas Roll2 controls the number
or hits per step and the hits' distance from each other. Rolls are most often used for percussion
sounds (particularly in drum tracks), but in principle they work with any type of track or sound.
Roll parameter is a more refined version of the Roll trigger. With the Roll parameter you can set the
number of notes played within the step, their intensity (range 0-15) and whether the intensity is
ascending or descending (D for descending, U for ascending). For example, setting 3D03 means the
note in the step will be played three times in quick succession, the first hit being played at a higher
velocity than the second and third. 3D15 means the same, except all three hits will be played at equal
velocity.
The Roll speed is relative to tempo. A slow tempo (e.g. 30bpm) is useful in evaluating the effect of
different intensity settings.
Note that the effect of the intensity parameter depends on the velocity sensitivity settings of your
synthesizer and/or patch.
Roll2 parameter can be used to play the step 2–5 times, but instead of velocity, you can control the
distance between the played notes. The distance is expressed in microticks. Each step consists of 96
microticks, and the first hit is always played at the first microtick in the beginning of the step. Setting
2×48 would play two notes, one at the beginning and the second at the middle of the step. If the
setting is 3×57, the resulting three notes will be longer than one step, i.e. longer than 96 microticks.
The first note will be played at the beginning the step, the second note will be played in the step at 57
microticks, and the third one will be played in the second step, at 18 microticks.
Note that the Roll parameters won't work if the Sustain setting on MODE page is on.
