Defining the Filter Envelope
See the Programming 
Basics section of this manual for 
detailed information about how 
the Envelopes work.
The Filter Envelope controls the filter frequency of the layer over time. The 
Envelope has six stages to the contour: Attack 1, Attack 2, Decay 1, Decay 2, 
Release 1 and Release 2. When a key is pressed, the Envelope goes through 
the first four stages. If the key continues to be held, the envelope holds at 
the Decay 2 level. When the key is released, the envelope immediately 
jumps to the Release 1 stage, then the Release 2 stage finally ending at the 
Release 2 level.
The default PatchCord 
settings connect the Filter 
Envelope to Filter Frequency but 
the envelope can be routed to 
any real-time control destination 
using a PatchCord.
Auxiliary Envelope The Auxiliary Envelope is a supplementary general purpose envelope that 
can be routed to any real-time control destination in the PatchCords. It is 
identical to the filter envelope generator. See “Filter Envelope” on page 222 
for full details.
