Peavey DPM V3 Owner's Manual page 45

The figure at the bottom of the preceding page is a typical wind instrument envelope.
It starts at a low level then rises over times T1 and T2 to a maximum level set by L2.
Then there's a slight decay to L3, which sets the sustain level (sustain is needed here
because a wind instrument will sustain for as long as you blow into it). Releasing the
key brings in a slight release time. Typical L values (0-4): 10, 80, 99, 49, 00. Typical
T values (1-4): 03, 03, 35, 03.

"Backwards tape" envelope
This is a "backwards tape effect" envelope. As long as you hold down a key, the note
will increase in level until it reaches L2. Since T3=0 and L3=0, immediately after
reaching L2 the envelope will go down to 0 and stay there. Setting T4 and L4=0 en-
sures that there won't be a release time if you release your fingers from the keys
before the envelope reaches L2. Typical L values (0-4): 00, 33, 99, 00, 00. Typical T
values (1-4): 15, 20, 00, 00.

This envelope is useful for bowed effects (such as cello) where you may want an at-
tack time, yet also want to retain the initial "scrape" of the bow against the strings.
