Globals
This is another toggle, which affects LFO2, ASR2, and FUNs 2 and 4. When off, these four
control sources are local; they affect each individual note in the layers that use them as a control
source. They begin operating each time a note in that layer is triggered.
When the Globals parameter is set to On, these control sources become global, that is they affect
every note in every layer of the current program, not just the one to which theyÕre applied.
When these control sources are global, they begin operating as soon as the program is selected.
When Globals are on, LFO2, ASR2, and FUNs 2 and 4 will appear on their respective pages
preceded by the letter ÒGÓ to indicate that theyÕre global.
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.
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 word
ÒNaturalÓ will change to ÒUser,Ó 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.
