Kurzweil Forte - Manual (Page 142)

Program Edit Mode
The LFO+ Page
7-45
With the Forte, you can set upper and lower limits on each LFO’s rate, and assign a control
source to change the LFO’s rate in realtime, if you wish.
Because of its periodic nature, the LFO is perfect for creating effects like vibrato (cyclic
variation in pitch) and tremolo (cyclic variation in amplitude). When you’re editing LFOs,
or any control source, remember that it must be assigned to control some parameter before
you’ll hear the effects of your edits.
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.

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. 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’s system tempo. Of course, if you choose to tempo sync
your LFO, then the LFO rate is fixed, and you can specify neither Maximum Rate nor Rate
Control. The display changes as shown below:
