Chapter 11 Advanced Sound Shaping Controls
41 Metallic sounds and more — with FM Depth
Like the vintage synthesizers of the past, the AN200 is absolutely loaded with modulation options — giving
you the power to mangle the sound in wild and unique ways. Yet it also gives you some intriguing digital
twists — like FM Depth.
Depending on the other Voice settings, FM Depth can be very subtle, adding harmonics or changing the
pitch — almost imperceptibly at times. It can also create harsh, metallic, non-pitched sounds — perfect
when you want to add some industrial edge or noise percussion to your tracks.
1 To start out, select a Pattern.
Try to select a Pattern with a soft, warm Voice that lets you hear some of the more subtle qualities of FM
Depth.
2 Turn the [VCO 1/2] knob all the way left.
This lets you hear only VCO 1 — important because FM Depth only modulates VCO 1.
3 Set the [FM DEPTH] knob to 12:00 (around 0).
This is center or zero for FM Depth — turn the knob in either direction from this point to change the
sound.
Turn it very slowly as you play the keyboard and hear how the Voice changes.
Try this out with a variety of Voices. Depending on the other Voice settings, FM Depth changes can be
very subtle — or extreme and harsh.
• Fine tuning
Since the sound and pitch can radically shift with even the slightest knob tweak, you may want
to use the [DATA] knob instead. This lets you control FM Depth much more slowly. Make sure
you turn [FM DEPTH] first, so that FM Depth is called up for the [DATA] knob.
• In sync — and out
Experiment with various Sync Mode (page 58) and Sync Pitch settings, too. These work
together with FM Depth in modulating VCO 1, and can dramatically alter the character of the
sound.
FM Depth
Determines the amount of modulation cre-
ated by the FM function. The further the
value is from midpoint (64), the greater the
modulation depth. Some settings can result
in a metallic sound with no discernable pitch;
some settings completely change the pitch.
