Random Weighting Parameters– Rests
The Random Weighting Parameters - Rests are made
available when at least one column in the grid has a rest and
at least one other Drum Sound turned on. This will happen
with either the 1: pool or 2: poly selected, since you can
have random rests in both modes; they just operate
differently (see the description under "Pools/Poly," below).
Whenever this step is encountered in playing through the
pattern and a random choice must be made, the likelihood of
a rest occurring can be favored by the use of a separate
weighting curve.
Rests-Random Factor
Controls the degree of slope to the Weighting Curve. 0 = a
Linear Curve with any Weighting Curve. Negative values
not only invert but rotate the curve. For examples, see
"Random Weighting Curves" on page 1104.
Rests-Weighting Curve
0: Exponential
2 different shapes are available, which affect the likelihood
of a rest occurring when a random choice is made. For more
information, see "Random Weighting Curves" on page 1104.
Associated Parameters
Pools/Poly
0: Poly
1: Pools
Chooses one of 2 modes of operation for the entire grid
when columns contain more than one Drum Sound and/or a
rest.
0: Poly
If there is more than one Drum Sound selected in a column
(and no rest), then all of the Drum Sounds at that step will be
played; if you had a kick, snare, and hi-hat in the same
column, all 3 would be played when that step was reached.
This is the typical operation of most grid-based rhythm
pattern software. However, if a rest is also selected, then
there will be a random possibility of a rest or a Drum Sound
for each of the Drum Sounds; in other words, if you had a
kick, snare, hi-hat and rest in the same column, for each of
the 3 Drum Sounds a choice between the sound and the rest
would be made (subject to the Random Rest Weighting
Curve described previously). This would result in one of 8
possible combinations:
• kick, snare, hi-hat
• (rest), snare, hi-hat
• kick, (rest), hi-hat
• kick, snare, (rest)
• (rest), snare, (rest)
• (rest), (rest), hi-hat
• kick, (rest), (rest)
• (rest), (rest), (rest)
1: Pools
If there is more than one Drum Sound selected in a column,
then those sounds form a "pool" of choices from which only
one will be chosen at random. If a rest is also selected, then

0: Exponential
With a positive Factor (+), choices will be exponentially
weighted towards the Drum Sounds/Notes more often. With
a negative Factor (-), choices will be exponentially
weighted towards the rests more often.
1: Logarithmic
With a positive Factor (+), choices will be logarithmically
weighted towards the Drum Sounds/Notes more often. With
a negative Factor (-), choices will be logarithmically
weighted towards the rests more often.
A Factor of 0 with any shaped curve yields a linear table
(straight diagonal line), and each of the values in the pool
will have an equal chance of getting chosen.

Weighting Curves and the Factor field on random rests:

there will be a possibility of a rest or only one of the Drum
Sounds. For example, if you had a kick, snare, hi-hat and rest
in the same column, there would first be a choice of one of
the 3 Drum Sounds (subject to the Random Pool Weighting
Curve described previously), then a choice as to whether to
play the single chosen Drum Sound or a rest (subject to the
separate Random Rest Weighting Curve described
previously). This would result in one of 4 possible choices:
• kick
• snare
• hi-hat
• rest
Keyboard Track
0: Off
Allows the Drum Pattern to track the input notes if desired,
thereby changing keys depending on the chord. 0: Off is
normal for Drum Patterns while 1: On is normal for Melodic
Patterns.
0: Off
The Drum or Melodic Pattern is "fixed" - it doesn't matter
what notes you play on the keyboard. The pattern will
always produce the same pitches, according to the settings of
the Drum Sound/Note settings. This is most typical for Drum
Patterns.
1: On
The pitches of the notes generated "track" the lowest key
played on the keyboard (or other input device), related to C2
(MIDI Note #36). This is most useful for Melodic Patterns.
In other words, when you play a C2, the pattern will be
produced using the Note Numbers as specified by the Drum
Sound/Note settings, and any other applicable parameters. If
