In the M-Band+Rvb algorithm, Row 5 contains parameters for cut-off frequen-
cies of low and high cut filters for each voice, as well as master low and high cut
controls for all voices.
Mstr LC/HC
Two master controls are provided in the first row position. Press Load/
✱ to
toggle between them. The High Cut Master allows simultaneous adjustment of
the high frequency cut-off points for the filters on all voices in single semitone
increments up or down from the individual voice settings. The Low Cut Master
allows simultaneous adjustment of the low frequency cut off points for the filters
on all voices in single semitone increments up or down from the individual voice
settings.
V1-V6 LoCut and HiCut
The low cut and high cut filters operate at 12dB/octave. There are individual low
cut and high cut filters for each of six voices. The ranges of the filter cut-off points
are from 20-20,000Hz at approximately semitone intervals across the entire
range for a total of 121 cut off points. The low cut filters have an OFF position
just below 20Hz. The high cut filters have an OFF position just above 20,000Hz.
In the Glide>Hall algorithm, Row 3 contains level, delay and feedback param-
eters for a pair of stereo gliding delays that precede the 6-voice delay.
Gld Lvl
Gld Lvl controls the stereo output level from all gliding delays (A, B, Left and
Right). It has a range of Full (0dB) down to -85dB and Off.
A Left (A Lvl L and A Dly L)
These parameters control the output level and delay time of the left channel A
Glide Delay. A Lvl L has a range of Full (+0dB), Phase Normal down to -85dB,
Phase Normal, OFF, -85dB Phase Inverted up to Full (+0dB), Phase Inverted.
A Dly L has a range of 0.0 milliseconds to 42.0 milliseconds in 0.1 millisecond
units.
A Right (A Lvl R and A Dly R)
These parameters control the output level and delay time of the right channel A
Glide Delay. They have the same ranges as A Left.
B Left (B Lvl L and B Dly L)
These parameters control the output level and delay time of the left channel B
Glide Delay. They have the same ranges as A Left.
B Right (B Lvl R and B Dly R)
These parameters control the output level and delay time of the right channel B
Glide Delay. They have the same ranges as A Left.
Fbk L/R
These parameters control the feedback levels of the corresponding left and right
channel Glide Delays. The range of these parameters is from +100% down to
1% (Phase Normal feedback), 0% (off), -1% up to –100% (Phase Inverted
feedback).
