Amplitude LFO Depth (-99 to +99)
At +00, the 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). Amplitude LFO parameters (such as speed and
wave shape) are programmed within the ALFO Function (see page 73).
Tip: Amplitude LFO set to a triangle wave gives tremolo effects.
Each sound can be restricted to a specific range of the keyboard. This is ideal for
creating splits (e.g., bass in the lower octave and a half, piano in the middle three
octaves, and strings in the upper octave).
Lower Limit (MIDI note 000 to 127/ C-2 to G8)
Specifies the lowest note of the soundÕs keyboard range. You can set the lower limit
by holding Quad Switch [1] and tapping the key on the keyboard you want to set as
the lowest note in the range.
High Limit (MIDI note 000 to 127/ C-2 to G8)
Specifies the highest note of the soundÕs keyboard range. You can set the high limit
by holding Quad Switch [2] and tapping the key on the keyboard you want to set as
the highest note in the range.
