To Change the Filter Cutoff Envelope:
Enabling the envelope generator allows the envelope to control the
cutoff frequency automatically.
1. Select page two by pressing the right cursor arrow.
VCF
Tracking: +1.00
Envelope Amt: +0%
Investigate the effects of envelope control over the filtered sound by
moving the cursor to the Envelope Amount. Use the Data Entry Control
to set a value of +40%. This allows the envelope to control the filter
cutoff frequency.
2. Select page three by pressing the right cursor.
VCF Attack: 0.20s
Hold: 0.00s
Decay: 0.00s
Sus:99% Rel:0.40s
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: 0.20s
Hold: 0.00s
Decay: 0.00s
Sus:99% Rel:0.40s
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.
