2. Select page three by pressing the right cursor.
VCF Attack:
Hold:
Decay:
Sus:99%
Move the cursor under the Attack time on line one and vary the data
entry control. With larger values, it will take more attack time for the
filter frequency to go from lowest to highest cutoff frequency. Vary the
various envelope parameters, and observe the effect these changes have
on the sound.
To check out inverted envelopes, set the envelope parameters as follows:
VCF Attack:
Hold:
Decay:
Sus:99%
Play and hold a chord. This is a non-inverting envelope in the sense that
the envelope increases the filter cutoff frequency above the initial cutoff.
To select an inverting envelope where the cutoff decreases below the
initial cutoff, press the left cursor arrow.
