4.2 Functions of buttons and knobs
4.2.1 Sound control knobs
The sound control knobs adjust the sound of the three sound sources, namely bass drum, snare
drum and hihat in Perform and Pattern mode.
When a knob is turned, the Xbase09 displays the current parameter value. In PERForm mode. the
values are processed additively. This means that the parameter value is loaded from the
performance memory and added to (or subtracted from) the value generated by the control knob.
This process is started by turning a sound control knob.
It can therefore happen that a parameter value can’t be set to maximum (127) by turning a knob
fully clockwise, as is the case when the value stored in performance memory is small and the
knob's starting point is in the last third of its range. If you want to set a higher value in this case,
turn the knob all the way down and then set the desired value. Apply the opposite of this
procedure if you can’t directly set a level low enough.
All knob movements are transmitted as MIDI controllers. When receiving these MIDI controllers,
the Xbase09 responds as though its own control knobs have been turned. The same applies for
"Track Record" and "Step Editt" modes. This means that sound editing in the Xbase09's internal
sequencer can also be made via MIDI. See the MIDI implementation chart to find out which
controller is mapped to a given parameter. This mapping is fixed and can’t be changed.
Note: The hihat section is a monophonic sound generator that can play one of six samples (closed
hihat, open hihat, crash cymbal, ride cymbal rim shot and clap) or analog noise. This is what is
meant by "hihat section" in this manual. Although it carries the name, the hihat section does not
always produce the sound of a hihat!
4.2.1.1 Bass Drum Parameter
TUNE
controls the pitch envelope amount on the bass drums VCO, just as on the TR 909. The
range of control has been increased.
PITCH
ranges from 25 Hz subbass to relatively high tones. This is the actual VCO tuning
parameter as opposed to TUNE.
DECAY controls the bass drums decay, just as on the TR 909. The range has been increased to
allow for "walking bass" sounds with a maximum decay of 2.5 seconds.
HARMONICS changes the harmonics of the bass drum’s VCO. The original sine wave is
gradually distorted by a diode limiter which makes for a harder, timpani-like sound.
PULSE
controls the pulse component of the attack
NOISE controls the noise component of the attack.
ATTACK controls how much of the PULSE and NOISE mix is added to the bass drum sound,
just as on the TR 909. PULSE is a square wave impulse, while NOISE generates a noisy clap-like
