5-3
You can set initial values for the following MIDI Controllers:
You may be wondering why you can set initial values for
these
MIDI Controllers and not others.
ItÕs because most of the PC2Õs programs use at least one of these MIDI Controllers to do
something (a common example is MIDI 1, which the Mod Wheel sends by default, and which
controls vibrato or tremolo in many programs). Appendix B contains a list of programs and
which MIDI Controllers the physical controllers are assigned to in each program.
The Envelope Menu
There are three parameters in the Envelope menu. They control how the amplitude of each layer
develops over time.
Attack
How fast the layer ramps up to full volume
Decay
How fast the layer fades to silence when youÕre sustaining notes by holding the keys or using
the sustain pedal
Release
How fast the layer fades to silence when you release notes by letting up the keys or releasing the
sustain pedal
These parameters control the
rate
of attack, decay, and release, which are known collectively as
the
envelope
of a sound. Each parameter is measured as a multiple of 1, which is the unadjusted
rate (thatÕs why thereÕs an
x
after the value). Higher values mean a
higher rate
, which means that
less time
elapses during the corresponding segment of the envelope. For example, if you want
notes to linger a long time after you let up the keys, set the Release parameter to a low value.
The LFO Menu
There are eight parameters in the LFO menu. Four of them control two LFOs (low-frequency
oscillators). The other four control the rotor effects of the organs in Internal Voices mode, and the
rotor effects of the KB3-mode organs. In many programs, the LFOs are activated by the Mod
Wheel; they add a vibrato or tremolo effect when you push the Mod Wheel up.
The LFOs are permanently linked to various sound-modulation functions, which vary from
program to program. These functions are in turn controlled by various physical controllers. For
example, most of the organs in Internal Voices mode use the Mod Wheel to change the speed of
rotary-speaker effects (which are produced by LFOs), while the KB3 organs use
SW1
(
Rotary
Fast/Slow
for the same purpose (although the KB3 organs donÕt use the LFOsÑthey have a
separate set of rotor-effect generators).
