Minimum Rate; Maximum Rate; Rate Control; Lfo Shape - Kurzweil K2661 Musician's Manual

LFO1 is always local, meaning that it's triggered with each Note On event, and runs
independently for each note in the layer. LFO2 is local by default, but can be made global. This is
done on the COMMON page, by setting the Globals parameter to On, which causes LFO2,
ASR2, FUN2 and FUN4 all to become global. Global controls uniformly affect every note in each
layer.
The top line of this page gives the usual mode reminder and tells you which layer you're
looking at. There are five parameters for each of the LFOs.

LFO Start Phase
Minimum Rate
This is the slowest rate at which the LFO runs. When its Rate control is set to OFF, or when the
control source assigned to it is at its minimum, the LFO runs at its minimum rate.
Maximum Rate
This is the fastest possible rate for the LFO. When its Rate control is set to ON, or when the
control source assigned to it is at its maximum, the LFO runs at its maximum rate.
Rate Control
Assign any control source in the list to modulate the LFO's rate between its minimum and
maximum. A continuous control like the Mod Wheel is a natural choice, enabling you to get just
about any rate between min and max. But you can use a switch control too, to get just the min or
max with nothing in between. Assigning MPress as the rate control for an LFO vibrato gives
you an easy way to increase the vibrato rate in realtime, as you can on many acoustic
instruments.
LFO Shape
The shape of the LFO waveform determines the nature of its effect on the signal its modulating.
There are diagrams of each LFO shape in the Musician's Reference; these will give you an idea of
how each LFO shape affects the signal. An easy way to check the effects of the different LFO
shapes is to set LFO1 as the value for the Src1 parameter on the PITCH page, and set the Depth
