Editing Presets
Every instrument in Xtreme Lead has it's own predetermined volume
envelope which is used when the Volume Envelope parameter is set to
“factory.” By setting the Volume Envelope to “time-based” or “tempo-
based,” we can reshape the instrument's natural volume envelope any way
we want. By reshaping the volume envelope of a instrument, you can
dramatically change the way the sound is perceived. For example, you can
make “bowed” pianos or backward gongs. The diagrams to the left show
the characteristic volume envelopes of a few common sounds.
In preparation for this experiment choose almost any of the standard organ
presets which continues to sustain when the key is held down. Go to the
Instrument page and set it to “None” on all layers except Layer 1. Now
you’re ready to play with the Volume Envelope.

To Setup the Volume Envelope
1.
Go to the Volume Envelope mode screen and set the Volume Envelope
mode to “time-based.”
2.
Now move on to the next screen to set the Volume Envelope
parameters.
3.
Increase the Attack 1 time value and play a note. The attack controls
the time it takes for the sound to reach the Attack level when a key is
pressed and held.
