[F4] NATIVE
With a Plug-in board installed to this synthesizer, you can create a Plug-in Voice by editing both native parameters (those parameters exclusive to the
particular board) and unique parameters (related specifically to this synthesizer).
Pressing [F4] gives you access to the native parameters of the Plug-in board. The parameters will vary depending on the Plug-in Board. For details about
each parameter and its functions, refer to the Owner's Manual or the on-line help that came with your Plug-in Board.
[F5] LFO (Low Frequency Oscillator)
From this display you can set the basic LFO parameters for modulating the pitch to create vibrato and other special effects.

PMod (Pitch Modulation Depth)
[F6] EQ (Equalizer)
From this display you can apply equalizer settings to the Plug-in Voice. This is a shelving equalizer
with two bands; one for high frequencies and the other for low frequencies.

LowFreq (Low Frequency)
LowGain (Low Gain)
HighFreq (High Frequency)
HighGain (High Gain)
Determines the speed of the LFO waveform. Positive settings increase the speed and negative settings
decrease it.
Settings: -64 ~ 0 ~ +63
Determines the delay time between the moment you press note on the keyboard and the moment the LFO
comes into effect. Positive settings lengthen the delay and negative settings shorten it.
Settings: -64 ~ 0 ~ +63
Determines the amount by which the LFO waveform controls the pitch. Positive settings increase the amount
and negative settings decrease it.
Settings: -64 ~ 0 ~ +63
Determines the shelving point for the low frequencies. The levels of signals below this frequency will be
boosted/attenuated by the amount set in the LowGain parameter.
Settings: 32Hz ~ 2.0kHz
Determines the amount by which signals below the LowFreq frequency will be boosted/attenuated.
Settings: -64 ~ 0 ~ +63
Determines the shelving point for the high frequencies. The levels of signals above this frequency will be
boosted/attenuated by the amount set in the HighGain parameter.
Settings: 500Hz ~ 16.0kHz
Determines the amount by which signals above the HighFreq frequency will be boosted/attenuated.
Settings: -64 ~ 0 ~ +63
