Lexicon Program Descriptions

13 Delay, Echo
The Delay, Echo variations include mono (5.5 seconds), stereo (2.7 seconds) and 6-voice multitap
effects. Each of the programs can be used for digital delay
or tape echo effects. When the Adjust
parameter (Page 1, Edit knob 1) is set to a value between 63 and 3, tape echo effects are produced.
(Each repeat is darker and softer.) When the Adjust parameter is set to a value between 64 and 127,
digital delay effects are produced. (Each repeat is the same timbre, but softer.)
In programs 90-97, Adjust also sets the amount of feedback — with an increasing number of repeats
as the parameter value is increased. Delay time is set with Tap. Each program is preset with a
different useful rhythm.
In Variations 98-104, the amount of feedback is preset and Adjust determines Delay time.
NOTE: In all of the Delay programs (including the Dual combinations), Delay times (e.g. L Dly 1, R
Dly 1 etc.) not controlled by Tempo, are scaled by the Master Delay parameter (MstrDly). In some
programs, Adjust controls MstrDly.
MstrDly values range from 0-100% and are set to 100% in most preset programs. If this control is reset
manually (or by Adjust) to less than 100%, individual delay times will scale accordingly. For example,
if MstrDly is set to 25%, delay times will be reduced to 1/4 of their normal value. Other knobs which
control those delay times become correspondingly less sensitive — requiring, in this example, 4 times
as manny clicks to obtain their normal result.
When using any type of delay or echo effects with music, always pay attention to the way the repeats fall
rhythmically to the beat. The most effective delay and echo patterns are those that lock in with the tempo
of the tune.
