2. Now we need to change over to DYNAMIC PROCESSING 14. Press ENTER to exit
from the current function (see GENERAL INSTRUCTIONS 3), and the display will show
the module identifier.
3. Key in 14 to select the filter envelope parameters.
4. Move the cursor under A and vary the slider. With larger values, it will take more
attack time for the filter frequency to go from lowest to highest cutoff frequency. Refer
to DYNAMIC PROCESSING 14, vary the various envelope parameters, and observe the
effect these changes have on the sound.
5. Now let’s check out inverted envelopes. Set the envelope parameters as follows:
F: A H D S R
01 01 07 01 01
... and 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, exit Function 14
by pressing ENTER (this puts you back at the module identifier), then key in 13.
6. We’re back at the familiar Filter Setup screen. Move the cursor under Env and select
-40 to invert the envelope. Note that the envelope effect is not all that noticeable when
you play a chord. This is because the envelope forces the cutoff frequency in a negative
direction, and since the cutoff frequency is already fairly low, it can’t go that much lower.
7. Now move the cursor under Fc and increase the cutoff frequency to around 90 or 100.
The effect will be far more noticeable since there will be more range available for the
negative-going envelope excursion.
8. If you feel like experimenting, play with the Trk control to affect the way the filter
frequency tracks the keyboard pitch (see DYNAMIC PROCESSING 13).
9. Before proceeding with the Tour, set Fc=100, Q=00, Env=+00, and Trk=1.00. Set the
envelope to A=01, H=01, D=01, S=32, and R=05 ( DYNAMIC PROCESSING 14). After
entering these values, press ENTER to return to the module identifier.
FUN WITH VCAS
1. In preparation for the following experiments, let’s change the current voice to include
the entire keyboard. Enter 00, then press Enter twice. You have now selected the entire
keyboard.
