Filter Envelope - E-Mu XK6Xtreme Keys Owner's Manual

Filter Envelope

The Filter Envelope is normally used to control the filter frequency and has
six stages. Unlike the Volume Envelope, the Filter Envelope must be
patched to the Filter Frequency using a PatchCord. In this respect, it can be
thought of as a general purpose envelope generator which is normally
patched to control the filter. The Filter Envelope Levels can be negative as
well as positive.
There are three mode options:
• Time-based: Defines the Filter Envelope rates from 0 to 127 (approxi-
mately 1 ms to 160 seconds). The Master clock has no affect on time-
based rates.

• Tempo-based: The Filter Envelope times vary based on the master tempo
setting and are displayed in values such as 1, 2, 3, etc. Note values are
displayed instead of a number when the time corresponds to an exact
note value. Tempo-based envelopes are useful when using arpeggiators
and sequencers because the envelope rates compress and expand accord-
ing to the Master Tempo setting, keeping the envelopes in sync with the
music. See the illustration on page 104.

• Envelope Repeat: The Envelope Generators can also be made to repeat.
When the envelope repeat function is On, the Attack (1&2) and Decay
(1&2) stages will continue to repeat as long as the key is held. As soon as
the key is released, the envelope continues through its normal Release
stages (1 & 2). For more information see page 104.
To Turn on Envelope Repeat:
Move the cursor until it is underneath the Mode field as shown below.
