Minimum Rate
is 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.
As previously mentioned, the values 1/4 note, 1/8 note, 1/8 triplet, and 1/16 note sync the
Minimum Rate with the Forte SE’s system tempo. Of course, if you choose to tempo sync
your LFO, then the LFO rate is xed, and you can specify neither Maximum Rate nor Rate
Control. e display changes as shown below:
Maximum Rate
is 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 minimum and maximum. But you can use a switch control
too, to get just the minimum or maximum with nothing in between. Assigning MPress
(aftertouch) 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
e shape of the LFO waveform determines the nature of its eect on the signal its
modulating. An easy way to check the eects of the dierent LFO shapes is to set LFO1
as the value for the Src1 parameter on the PITCH page, and set the Depth for Src1 to 400
cents or so. en go to the LFO page, set the Min and Max rates for LFO1 at 0.00Hz
and 4.00Hz or so, and set the Rate control to MWheel. Now play your MIDI controller
