Every instrument in Vintage Keys 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 Vintage Keys have
been preprogrammed to adjust these four volume envelope parameters. A
diagram of this standard ADSR envelope is shown below.
