5. Using the "Auto Key" feature.
"Auto Key" is an automatic key transposition feature that helps
you learn a pattern in every key and works great with the
"performance" and "teacher" patterns. To turn "Auto Key" on,
press the "DRUMS" button repeatedly or hold it down while
turning the large data wheel until you have highlighted the
"Auto Key" menu item. Turn the large Data Wheel to toggle
this feature on and off.
"Auto Key" starts with the current key and increments
based upon the "Key Delta" within its predetermined range
(see Drums Mode, page 10). If the interval exceeds the
predetermined range of the key, "Auto Key" will adjust an
octave down. Using larger interval settings (i.e. MAJ7) will
cause the octave adjustment to occur more often.
"Key Delta" is the interval by which the pattern will be
transposed. The new key occurs each time the patten repeats,
is measured in intervals (distance between the original key
and the new key), and is selectable between a minor second
and a major seventh.
Auto Key "Key Delta" Interval options:
MIN2
Moves chromatically (1/2 step) through all 12 keys
MAJ2
Moves in whole steps (= two 1/2 steps) through six keys
MIN3
Moves in minor thirds (1-1/2 steps) through four keys
MAJ3
Moves in major thirds (2 steps) through three keys
PERF4
Moves through the cycle of fourths (2-1/2 steps) in all 12
keys
TRI
Moves in tritones (3 steps) through two keys
PERF5
Moves through the cycle of fifths (3-1/2 steps) in all 12
keys
MIN6
Moves through minor sixths (4 steps) in three keys
MAJ6
Moves through major sixths (4-1/2 steps) in four keys
MIN7
Moves through minor sevenths (5 steps) in six keys
MAJ7
Moves through major sevenths (5-1/2 steps) in all 12 keys
6. Adjusting the volume of each background
track.
To adjust the volume of each instrument playing, press the
"DRUMS" button repeatedly or hold it down while turning
the large Data Wheel until you have highlighted the desired
instrument (drums, bass, acc1, acc2). Turn the large Data
Wheel to increase or decrease the volume of that individual
track.
A fun exercise is turning down all the instruments except the
drum track. Since the performance loops are mostly made
up of two separate music sections, this gives you a "digital
drummer" complete with fills and varying feels.
