The Amplitude Envelope (AMPENV) Page
6-35
YouÕll use global control sources when you want to affect each note in a given layer uniformly,
and local control sources when you want to affect each layerÕs note independently. For example,
youÕd use a global LFO controlling pitch to create a Leslie effect on an organ sound, since you
want the affect applied to all the notes you play. YouÕd use a local LFO controlling pitch to create
a vibrato for a solo violin, since you want to be able to vary the rate and depth of the vibrato for
each note.
OutPair
When Globals are off, the OUTPUT page for each layer determines the KDFX input to which the
layer sends its audio output. This enables you to apply a different effect to each layer. Turning
Globals on overrides the settings on each OUTPUT page, causing every layer in the program to
be routed to the KDFX input you specify for the Outpair parameter. This is a quick way to apply
the same effect to every layer in the program.
The Amplitude Envelope (AMPENV) Page
Amplitude envelopes have three sections: attack, decay, and release. The attack section
determines how long each note takes to reach its assigned amplitude level after you trigger a
Note On event. The decay section determines how quickly and how much a sustained sound
fades before a Note Off is triggered. The release section determines how quickly a sound fades
to silence after a Note Off is triggered.
Press the AMPENV soft button to reach the Amplitude Envelope page. For many programs, it
will look like the diagram below, which tells you that the amplitude for the current layer is the
default, ÒnaturalÓ ROM amplitude envelope thatÕs applied to each sample and waveform
during its original development process. YouÕll leave the amplitude envelope in Natural mode
when you donÕt want to change the way the current layerÕs loudness develops.

If you want to build your own amplitude envelope, just turn the Alpha Wheel a click. The value
Natural will change to User, and a set of AMPENV parameters will appear. The sound will
change when you do this, because the default settings for the User envelope, as shown in the
diagram below, take effect as soon as you leave Natural mode. Returning to Natural mode
applies the original amplitude envelope once again.
