Aftertouch Depth (-99 to +99) Page 2

At +00, aftertouch has no effect on the amplitude. Applying aftertouch with this parameter set to a positive value raises the amplitude; conversely, applying aftertouch with a negative value will make the sound softer the harder you press. The higher the number (either positive or negative), the greater the effect for a given amount of aftertouch.

TIP: Use aftertouch to “swell” the amplitude of string and horn parts. But please note: Notes played at maximum velocity will probably not have the "headroom" available for a positive-going amplitude swell. Try playing some soft, medium, and loud notes while experimenting with this parameter.

Amp LFO Depth (-99 to +99) Page 3

At +00, the Amp LFO has no effect. Higher positive values increase the amount of LFO modulation. Negative values give the same apparent effect, but with reversed LFO phase (i.e., if the amplitude would normally be increasing with depth set to a positive number, the amplitude would instead be decreasing at that same moment had the depth been set to a negative number). Amp LFO parameters (such as speed and wave shape) are programmed within the Amp LFO Function on button [8] (see pages 147-148).

Note: If you hear no change when you alter this parameter, spend some time experimenting with the Amp LFO Functions on button [8].

Another note: If your Amplitude LFO is using the Square, Up Saw, Down Saw, or Random+ waveshapes, you may get a more pronounced effect if you use a negative setting for Amp LFO Depth. See page 144 for more information about the various LFO waveshapes.

TIP: Amp LFO set to a triangle wave gives tremolo effects.
