Every instrument in Proteus 1000 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.
