Compare; Bypass - Lexicon PCM 90 - REV 1 User Manual

Whenever you edit a PCM 90 effect from the front panel, the LED in the
Compare button will light. This lets you know that the effect has been altered
since the last store operation, and that the edit compare function is active.
Whenever this light is on, you can press Compare to hear the original version
of the effect. A message will be displayed to inform you that the stored version
of the effect is being loaded. Although this message is only displayed briefly, the
Compare LED will flash to let you know the effect you are hearing is the stored
version. While Compare is on, you can use the SELECT knob and the Up and
Down buttons to view parameter values in the stored effect.
Press Compare again to reload your edited version. Another message will be
displayed, and the Compare LED will stop flashing and remain lit until you store
your edited version, or select and load another effect.
Note: Altering parameter values with patched sources other than ADJUST or
Custom Controls will not light the LED.
The Compare light is off until
you make changes to an effect.
As soon as you alter an effect,
