affect the settings. You may
want to disconnect the
PatchCords to gain total control
of the envelope parameters.
(Alternately, you can create a
completely blank preset and start
from there.)

Every instrument in MP-7 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
