648| Effects for the Sounds
When “Sweep Mode” is set to LFO, the effect uses LFO to sweep in cycle.
c: Envelope Sens
This parameter sets the sensitivity of auto-wah. Increase the value if the in-
put signal is too low to sweep. Reduce the value if the input signal is so high
that the filter is stopped temporarily.
c: Envelope Shape
This parameter determines the sweep curve for auto-wah.

d: LFO Frequency [Hz]
e: MIDI Sync
When “MIDI/Tempo Sync”=Off, the LFO speed uses the LFO Frequency pa-
rameter setting. When “MIDI/Tempo Sync”=On, the LFO speed follows the
“BPM”, “Base Note”, and “Times” settings.
e: BPM
e: Base Note
e: Times
One cycle of LFO sweep is obtained by multiplying the length of a note ( r … w )
(selected for “Base Note”, in relation to the tempo specified in “BPM”, or the
MIDI Clock tempo if “BPM” is set to MIDI) by the number specified in the
Times parameter.
