Algorithms and Parameters
PCM 81
DELAY TIME
In each algorithm, the Delay Time row contains parameters for
delay settings of each voice, as well as master delay parameters for
all voices.
Press Load/✱ to cycle through selections: Master, GldResp,
GldRange and Clear.
Master
This control allows you to simultaneously change the delay times
of all voices in the effect. The available range is from 0-200%. This
provides a simple way to expand or close in all of the voice delay
times. If a voice's delay time is set to 500ms, changing the setting
of the Master parameter to 200% will change the delay time to
1000ms. Setting this parameter to 0% is an easy way to set all the
delays to 0 from a single control.
GldResp
In all of the 4-Voice algorithms, and in the Chorus+Rvb algorithm,
this parameter controls the response of the glide. The range is
0-100, with a typical default setting of 50. This setting provides a
good, real-time glide. Changing a delay time from 0 to 100ms with
a glide response of 0, causes the glide delays to take a minute or
more, allowing subtle changes in delay times and echoes with no
noticeable pitch shifting. A glide response of 100 is ultrafast,
causing high speed pitch shift, and even chirping effects with large
delay time changes.

ADJUST
This control allows you to specify the range of control of the
ADJUST knob when it is patched to a parameter. Low and High
settings are available, allowing you to select full range (0-127) for
those parameters where it is appropriate and to limit the range in
other cases. You can, for example set the Low value to 0, and the
High value to 1, to have ADJUST behave as an on/off control. Many
of the presets take advantage of this, and have ADJUST range
limits which are appropriate to the specific parameter.
