If a track is Forced To Scale, the EDIT page displays the notes that the track is actually going to play,
the unallowed ones having been forced into the allowed ones; the “real” notes recorded on the track
will nevertheless be visible in the right LCD (top row) for the current cursor position, and they will
reappear on the track when the Force To Scale setting for the track is switched 'off'.
If Root is set to 'Keyb', the root note is controlled by the keyboard. The note is taken from the same
source as the Transpose note of a track, which means the keyboard intended to control the root note
has to be sending on a T&A bus (see section 4.1.1.). In this case the right LCD is empty.
6.3. Random generator
Random generator allows you to randomise the data of parameter or trigger layers (and for drum
tracks, drum instrument layers). The randomiser menu is found in the main menu, with U
GPB7 (Rand), or with EDIT + GP13–14.
On the randomiser page you can use GPK9 to scroll through the available layers in the active track.
LayA, LayB etc. denote parameter layers, and TrgA, TrgB etc. denote trigger layers. If the active track
is a Drum type track, drum instrument names are available instead.
Because the layers are called just LayA, TrgB etc., you have to remember yourself which functions
you have assigned to each layer. If you have more than four parameter layers available (depends on
track initialisation), you can check the layer assignments quickly by pressing parameter layer
selection button C. Likewise, trigger layer assignments can be checked by pressing trigger layer
selection button C.
Parameter layers are randomised by setting the intensity of the randomisation. Randomisation starts
from parameter value 64, and the randomisation setting allows you to determine how much the
random values will deviate from 64. For example, if you enter an intensity value of 5, the randomised
value will be 64 +/- 5, in other words, a randomly picked value between 59 and 69. A value of “–” will
mean the randomiser will not change the values in that parameter layer.
For trigger layers, the randomiser value denotes the likelihood of the trigger getting turned 'on'; the
higher the number, the more likely it is that the trigger in each step will be 'on'. For example, if you
choose TrgA (Gate by default) for randomisation, a value of 1 will result in only a few steps having
their gates turned 'on', while a value of 14 will result in almost all steps having their gates switched
'on'. By selecting 'All' you can have the randomisation occur for all steps. A value of “—” means
randomiser will not change the values in that trigger layer.
Randomising drum instrument layers works the same way as randomising trigger layers.
You can randomise any number of a track's parameter and trigger layers simultaneously by assigning
values to all the layers you want to randomise. When you have selected the ones you want to
randomise, press GP2–3 to effect the randomisation. If you are unhappy with the result, you can undo
it with GPB8 ('Undo'). GPB7 ('Util') takes you back to the UTILITY page, and GPB6 ('Clr.') will clear the
active track (which can be undone as well with 'Undo').
Note, Velocity and CC parameter layers, and Gate, Accent and Roll trigger layers are obvious targets
