Every instrument in XK-6 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 sustain as long as 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.
Adjusting the Volume Envelope (the easy way):
Many sounds don't require a complex six-segment envelope. Over the
years, a simpler Attack-Decay-Sustain-Release envelope, or ADSR, have
become standard. The front panel controller knobs on XK-6 have been
preprogrammed to adjust these four volume envelope parameters. A
diagram of this standard ADSR envelope is shown below.
