The Algorithms and Their Parameters
Parameters in this row provide level and phase setting for feedback of individual
voices, as well as a master feedback parameter for all voices. In the Glide>Hall
algorithm, a duplicate set of parameters is included for cross-feedback.
Master
A Master Feedback control is available in effects which have a feedback level
control for each voice. It allows the feedback level for all voices to be simulta-
neously adjusted over a range of 0-100%.
Voices
In the 4-Voice algorithms, four voice controls are provided for adjustment of the
level and polarity of signals recirculated back to the input of individual voices.
Note that, as Voices 1 and 2 and Voices 3 and 4 are paired, caution should be
observed not to create feedback within a pair which exceeds more than 100%.
In the Chorus+Rvb and the M-Band+Rvb algorithms, six voice parameters
control the feedback level of the voice delays. Voices 1, 2, and 3 Fbk control the
individual voice feedback levels from the left channel voice delay outputs to the
left channel delay feedback input. Voices 4, 5, and 6 Fbk control the individual
voice feedback levels from the right channel voice delay outputs to the right
channel delay feedback input.
The range of these parameters is from +100% down to 1% (Phase Normal
feedback), 0% (Off), –1% up to –100% (Phase Inverted feedback).
In the Glide>Hall algorithm, the Feedback row provides both Feedback and
Cross Feedback parameters as described below. Press Load/✱ at each row
position to toggle between Feedback and Cross Feedback parameters.
Mstr Fbk, Mstr X-Fbk
These parameters allow the feedback and cross feedback levels for all voices
to be simultaneously scaled over a range of 0-100%.
Voices 1-6 Fbk, X-Fbk
These parameters control the feedback and cross feedback levels and the
polarity of the voice delays.
Voices 1, 2, and 3 Fbk control the individual voice feedback levels from the left
channel voice delay outputs to the left channel delay feedback input.
Voices 1, 2, and 3 X-Fbk control the individual voice feedback levels from the left
channel voice delay outputs to the right channel delay feedback input.
Voices 4, 5, and 6 Fbk control the individual voice feedback levels from the right
channel voice delay outputs to the right channel delay feedback input.
Voices 4, 5, and 6 X-Fbk control the individual voice feedback levels from the
right channel voice delay outputs to the left channel delay feedback input. The
range of these parameters is from +100% down to 1% (Phase Normal feed-
back), 0% (off), –1% up to –100% (Phase Inverted feedback).
The sum of all Fbk and X-Fbk values for each channel should be less than 100%.
