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 (see page 75).

TIP: Amp LFO set to a triangle wave gives tremolo effects.
Lower Limit (MIDI note 000 to 127/ C-2 to G8)	Page
4

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).

The Lower Limit specifies the lowest note of the sound’s keyboard range. You can set the lower limit by holding [80] 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) Page 5

Specifies the highest note of the sound’s keyboard range. You can set the high limit by holding [80] and tapping the key on the keyboard you want to set as the highest note in the range.

Program Sound Range

TIP: By setting the lower limit above the high limit, you can create a “hole in the middle” effect. This makes the sound appear to have two zones. All notes from the bottom of the keyboard to the high limit note will play, and all notes from the lower limit to the top of the keyboard will play, but the notes between the high limit and the lower limit will not play. This can be further enhanced in Mix Mode by using the Range function in Mix Edit Mode to cap-off the lower and high limits.
