Kurzweil K2600 Musician's Manual page 573

Programming Examples
Press the more> soft button, and the three soft buttons that select the control-input pages for the
lowpass Þlter will appear. Press the F1 FRQ soft button.
The Coarse Adjust parameter will already be selected. Try a few different values for this
#
parameter, to get a feel for its effect on the sound. Then set it to a value of G 3 208 Hz. Use the
cursor buttons to select the Src1 parameter, and set its value to MPress (3, 3, Enter). Cursor
down once to the Depth parameter, and set it to a moderate value, like 3800 cents. Now try
playing and applying pressure to the keys. (Obviously, this will have no effect if your MIDI
controller doesnÕt send mono pressure.)
Now weÕre going to use an envelope to control the sweep of the Þlter. The K2600 has one
envelope dedicated to shaping the output of the sound; this is called AMPENV. However, two
other envelopes (ENV 2 and ENV3) can be assigned to control other parameters. You can assign
AMPENV as a Control Source, but using ENV2 and ENV3 lets you assign separate envelopes to
do different things.
Cursor down to the Src2 parameter, and set its value to ENV2 (1, 2, 1, Enter). Move the cursor
down to the DptCtl parameter and set its value to ON. Cursor down to the MaxDpt parameter,
and set its value to 5800 cents. As soon as you set a depth, youÕll hear the envelope sweep the
cutoff frequency. WeÕll adjust it further in a minute. The F1 FRQ page should now look like this:
Edit|Prog:F1|FRQ(4P|LOPASS)|>Layer:1/1||

<more||F1|FRQ|F2|RES|F3|SEP|F4|AMP|more>
Next, press the F2 RES soft button to select the page for adjusting the resonance of the lowpass
Þlter. Select the Src1 parameter, and set its value to Data (6, Enter). Select the Depth parameter
and set its value to 30.0 dB. This means that the partials at the cutoff frequency will be boosted
30 dB. The F2 RES page should look like the following diagram.
If your MIDI controller has a data slider (or a control that can be programmed to send MIDI 06),
the data slider (or programmable control) will now affect the resonance of the Þlter. Be aware
though that the change in resonance is subtle; resonance affects some waveforms more
noticeably than others. You may want to set the Pad parameter on F1 FRQ page to a value of
18dB or so, then set the Gain parameter on the OUTPUT page to the same value; this reduces the
potential of clipping due to resonance.

Next press either of the <more> soft buttons until you see the ENV2 soft button. Press it to select
the ENV2 page. Here youÕll program Envelope 2 to control the ÞlterÕs cutoff frequency.
