2–2: OSC1 LFO (Oscillator 1 LFO)
18
2–2c: Frequency Modulation
These settings (KeyTrack, JS(+Y), Alternate Modulation) affect the speed of the oscillator 1 LFO.
KeyTrack (Keyboard Tracking) [–99…+99]
With positive (+) settings, the oscillator 1 LFO will become faster as you play higher on the key-
board.
With a setting of +33, the LFO speed will double as you play one octave higher on the keyboard,
and will be halved as you play one octave lower on the keyboard. Similarily, with a setting of +66,
the LFO speed will be increased to 4 times (decreased to 1/4th), and with a setting of +99 to 8
times (decreased to 1/8th).
With negative (–) settings, the oscillator 1 LFO will become slower as you play higher on the key-
board. The relation between the parameter value and the change in speed will be the opposite
from positive values.
With a “1–2: OSC” setting (☞ page 9 in this manual) of 8' the center key will be C4.
JS (+Y) (Joy Stick (+Y)) [0…99]
The higher this value is set, the faster the oscillator 1 LFO speed will become when you push the
joystick away from you.
With a setting of 99, the LFO speed will be increased by approximately 64 times when the joystick
is pushed all the way forward.
Alternate Modulation
AMS (Alternate Modulation Source) [OFF…Tempo]
Select the source that will control the frequency of the oscillator 1 LFO.
With a setting of OFF, there will be no modulation.
Intensity [–99…+99]
The time-related parameters of the LFO (“2–2a: Freq”, “2–2b: Delay, Fade”) can be temporarily
changed by the selected Alternate Modulation Source.
With settings of 16, 33, 49, 66, 82, and 99, the LFO time-related parameters will be multiplied
respectively by up to 2, 4, 8, 16, 32, and 64 times (or decreased by 1/2, 1/4, 1/8, 1/16, 1/32, or 1/
64).
If AMS is set to EG or LFO, the maximum available range of control allows the time-related
parameters to be modified over a range from 1/64th to 64 times their original values. (The LFO
allows an additional offset to be specified.)
If AMS is set to Controller, positive (+) values of this parameter will allow time-related parame-
ters to be shortened, to a maximum of 1/64th of their original time values. With negative (–) val-
ues, time-related parameters will be lengthened, to a maximum of 64 times the original values.
If AMS is set to SW1 or SW2, the time-related parameters can be shortened to as little as 1/64th or
lengthened to as great as 64 times their original value.
If AMS is set to Tempo, a setting of +16 for this parameter will cause the time-related parameters
to be shortened to half their original value when the tempo is doubled. This allows LFO speed to
track the tempo.
