[R] [M] [S] buttons (VINTAGE FLT TYPE)
If a vintage type model is selected, these buttons change the type of lter.
[R] models a Roland lter, and [M] and [S] model vintage synthesizers made by
other companies.
[CUTOFF FREQ] knob (CUTOFF)
Species the cuto frequency of the low-pass lter.
The frequency region above the cuto frequency is
cut, producing a more mellow tonal character.
[RES] knob (RESOANCE)
Boosts the region of the lter’s cuto frequency.
Higher values produce a stronger result, giving the
sound a distinctively synthesizer-like character.
[HPF] button (HPF STEP)
Sets the high-pass lter’s cuto frequency in four steps.
LFO (FILTER MOD)
Adjusts the amount by which the LFO modulates the
cuto frequency.

Adjusts the amount by which the envelope selected by the
MODE modulates the cuto frequency.
KEY F (FLT KEY FOLLOW)

the cuto frequency (key follow). With smaller values, the
cuto frequency becomes lower as you play higher notes.

Adjusts the amount by which the envelope selected by the
[MODE] button aects the velocity.
[MODE] button (FLT ENV MODE)
