39 Going negative — with FEG Depth
As we promised in the last Tip, here’s a sound-creating pointer that takes advantage of the negative values of
FEG Depth. Try these settings out — and hear what it’s like on the “minus” side of the sound.
1 First, get everything set up with the following settings:
EG [SELECT]...........to “ALL” (both FEG and AEG)
[ATTACK] ................to around 2:00 (90 - 100)
[DECAY]..................to around 1:00 (80)
[SUSTAIN] .............. to around 3:00 - 4:00 (100 - 120)
[RELEASE]..............to around 1:00 - 2:00 (80 - 90)
[CUTOFF]................ to around 2:00 (100)
[RESONANCE] ........ to around 2:00 (70)
2 Finally, set the [FEG DEPTH] knob to 7:00 (-128) — the maximum negative
value.
3 Now, play several single notes, slightly apart, and listen for the very slow
attack and the long sustain. Hear how the filter slowly sweeps and grows
with the sound?
A negative FEG Depth setting reverses the FEG operation — producing a filter sweep effect that dips down
instead of peaks. This means the sound gets softer and more muffled, until the end — when the filter
sweeps back up again.
Try these, too
Experiment with higher Cutoff and Resonance settings than the ones shown above.
Adjust the FM Depth, Sync Pitch, and Noise Level settings — to give the Filter some richer
harmonics to work with, and make the sound more interesting.
For even greater degrees of weirdness, try some long Portamento settings, too (for example,
around 90 - 110).
