Advanced features
The A-Station will respond to Pitch and Modulation wheel infor-
mation from a MIDI keyboard. The response is set using the
Wheels Menu - KEY 8.
Setting up a Pitch change when pushing a wheel forward
Press KEY 8 (ensure the function switch is in SHIFT mode) and
the display will show
b 1
alternating with a numeric value
.
The
value indicates how many semi-tones the pitch will change for
Oscillator 1 when moving the pitch wheel.
Adjust the PORTA/DATA knob until the desired number of semi-
tones is displayed. This affects the current program being lis-
tened to. Display values 1-12 will result in a higher pitch when
the wheel is pushed forward. Display values -1 - .12 will result
in a lower pitch.
Subsequent key presses of Key 8 will scroll through
the Wheels menu as described in the table opposite.
NOTE: If the current program uses more than one
Oscillator, it is recommended that the bend amount is
set equal for each Oscillator. If chord type effects are
required when moving the pitch wheel, different pitch
bend amounts may be set for each Oscillator.
Changing the Absolute Pitch using the
Modulation Wheel
During performance it may be desirable to drastically
change the pitch of all the Oscillators using the
Modulation Wheel. Repeatedly press KEY 8 (ensure
the function switch is in SHIFT mode) until the display shows
P
A
alternating with a numeric value
.
Adjust the PORTA/DATA
knob. A value from -1 to 64. will result in a lower pitch being
generated when the mod wheel is pushed forward. A value
from 01 to 63 will result in a higher pitch being generated when
the mod wheel is pushed forward.
Setting up Vibrato using the Modulation Wheel
During a performance it is often desirable to introduce a Vibrato
effect by pushing the Modulation Wheel forwards or backwards.
A Vibrato effect is simulated by adding a small amount of pitch
modulation to the Oscillators. The A-Station allows modulation
from LFO 1 to alter the pitch of the Oscillators. Repeatedly
press KEY 8 (ensure the function switch is in SHIFT mode)
