VOICE COMMON
Summary: Assigns keyboard after-touch to ampli-
tude modulation, pitch modulation, pitch control,
or level control — or any combination of the
above.
Settings: AM (Amplitude Modulation): off, on
PM (Pitch Modulation): off, on
Pit (Pitch Control): -12 ... 0 ... +12 max.*
Lev (Level Control): off, on
Procedure: Use the and
Details: As with the modulation wheel, amplitude
modulation produces a tremolo effect while pitch
modulation produced a vibrato effect. The harder
you press a key, the deeper the modulation. This
is only an "off/on" switch, however, and the
maximum depth of modulation to be applied must
be set using the LFO AM Depth and PM Depth
parameters in the ELEMENT TONE edit mode.
When after touch is assigned to amplitude or
pitch modulation, LFO modulation can only be
applied via after touch.
The Pit parameter allows keyboard after touch to
be used for note bending. The greater the key
pressure the greater the amount of pitch bend.
Positive values produce an upward bend when
key pressure is applied, and minus values pro-
duce a downward bend. Each increment from
represents a semitone. A setting of "0" pro-
duces no pitch bend. A setting of "12" allows a
maximum upward pitch bend of one octave,
while a setting of "-4" allows a maximum
downward pitch bend of a major third.
When the Lev parameter is turned on it becomes
possible to control the level of the sound over a
limited range by keyboard after touch. The
amount and direction (i.e. an increase or de-
crease) of level change depends on the setting of
the AFTER TOUCH SENSITIVITY parameter
in the ELEMENT TONE edit mode.
If both WHEEL and AFTER TOUCH are
assigned to modulation control, the controller via
which the highest modulation level is applied
will take priority when both are used simul-
taneously.
* This range may be more limited in some cases.
An exclamation mark (!) will appear after the
range value when the limit is reached.
cursor keys to
place the underline cursor under the AM, PM,
Pit, or Lev parameter. The arrows at either end
of the display mean that more parameters can be
accessed by scrolling in the indicated direction.
Use the [-1/NO] and [+1/YES] keys to turn the
AM, PM, and/or Lev parameter on or off, or to
select the desired Pit control range.
place the underline cursor under the AR or RR
parameter. Use the [-1/NO] and [+1/YES] keys
to set the selected parameter as required.
Summary: Sets the overall attack and release rates
for the current voice.
Settings: AR (Attack Rate): -99 ... 0 ... +99 max.*
RR (Release Rate): -99 ... 0 ... +99 max.*
Details: Although much more detailed envelope
programming capability is available for individual
elements (see the ELEMENT ENVELOPE edit
mode), these functions provide an easy way to
adjust the most important envelope parameters
for the overall voice. Positive values produce a
faster attack or release time, while negative
values produce a slower attack or release time.
You might want to lengthen the release time of a
voice, for example, to produce a lingering sustain
effect after you release the keys.
