its value to 5800 cents. As soon as you set a depth, you'll hear the envelope sweep the cutoff
frequency. We'll adjust it further in a minute. The F1 FRQ page should now look like this:

Next, press the F2 RES soft button to select the page for adjusting the resonance of the lowpass
filter. 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 filter. Be aware
though that the change in resonance is subtle; resonance affects some waveforms more
noticeably than others.

Next press either of the <more> soft buttons until you see the ENV2 soft button. Press it to
select the ENV2 page. Here you'll program Envelope 2 to control the filter's cutoff frequency.
The Att1 time parameter will already be selected; set its value to 0.50 seconds. Press the right
cursor button once to select the Att2 time parameter and set its value to 1.06 seconds. Cursor
down once to select the Att2 level parameter and set its value to -1%. Cursor right once, then up
once, selecting the Att3 time parameter. Set its value to 3.52 seconds. The ENV2 page should
look like the diagram below. Play around with the sound a bit. Hold a few notes through the
full length of ENV2; the sound will continue to change for several seconds. Work your
controller's Mod Wheel and data slider through several different positions to get an idea of the
range of variation you can add by using the two control sources in tandem.
