Beats
Beats is a another independent, 16-track play-only sequencer optimized for
live performance and groove creation. BTS riffs, which are permanently
stored in sound ROM, are special multi-part Audition Riffs.
(See pages 24, 38
& 244.) By playing keyboard or trigger keys you trigger, latch and unlatch
different parts of these synced loops and grooves. Any preset can be
selected and used by assigning a BTS riff
(or KIT riff) in the Preset Edit menu.
Here’s how it works:

Remember to SAVE your
preset once you assign a BTS or
KIT riff.
1.
Select a bts: preset, …or assign a BTS riff to one of the percussion
presets in the Preset Edit Menu. KIT riffs also have several tracks.
2.
Set the “Trigger Buttons Function” in the Controllers menu to Play
Beats Parts .
3.
Select Triggers in the Command Functions section.
4.
Each of the Beats Parts is assigned to a trigger key. Bring each part in or
out by pressing that key. Keys can also be Latched
(press the key once to
turn the part on, press it again to turn the part off) . Other control keys
allow you to Mute All Parts, Clear All Parts, and Start & Stop the beat.
For BTS Riffs the 16 parts are arranged in the following manner:
For each Beats Riff, you have 2 Grooves, 4 Fills which correspond to the
four parts of the Main and Alternate groove, and 4 Instrument parts. By
adding and removing parts, you control the complexity of the groove.

Beats (bts:) Riffs are
special 16-part audition riffs
made especially for use with
Beats mode. KIT riffs may have
four or five parts.
Other riffs usually have only one
part recorded.
Each part can also be scaled by Key Velocity , allowing you to fade parts in
and out (if velocity is routed to volume) as you play, or can be Transposed
over a six octave range. Each part can be assigned to any one of four Groups,
which allow multiple parts to be triggered from a single key. You can only
access Groups using the keyboard trigger keys. See the Factory Setup
diagram on the next page.
The factory BTS riffs range from 4-16 bars long, using 4 to 16 tracks each.
Normally you’ll use the Command Function buttons to bring parts in and
out. Beat Parts can also be assigned to groups so that multiple parts can be
triggered from a single key press. The Group Triggers, Clear Parts, Trigger
Hold and Mute keys are only accessible via MIDI or the keypads.

By assigning Trigger
Buttons to the keyboard Beats
Layout Keys, you can trigger
Beats and MIDI notes using the
Trigger buttons.
Trigger layouts are saved with the Multisetup. The Factory Multisetup (63)
has all the Beats controls assigned to the keyboard as shown in the diagram
on the following page. These MIDI note numbers have been placed below
the lowest key on the keyboard so as not to interfere with normal playing.
Setting the Beats Keys Offset function
(page 269) to +48 will allow you to
access these hidden control keys.
