Whether Tempo Mode is set to Global or Pgm, you can set a new tempo rate
by pressing the front panel Tap button twice. Alternatively, you can choose to
have tempo set automatically from incoming MIDI clock. The rate you tap, or the
MIDI tempo, will be displayed here.
For more information about working with the tempo parameters, see Tempo
Mode later in this chapter.
1.3 Bypass Mode/Bypass Src
This control alows you to determine the behavior of the PCM 90 when the front
panel Bypass button is pressed. You can also assign an external controller to
perform identically to the front panel button. When the Bypass button is pressed,
the LED will light, and a message indicating bypass type will be displayed.
Pressing Bypass again will turn bypass off.
The choices available via ADJUST are:
AllMute: Mutes both the input and the output signal, giving com-
plete silence.
InputMute: Mutes the input to the PCM 90, allowing the tail of the
effect to ring out. (This is the default setting.)
OutputMute: Mutes the output. Audio signals are still being fed to the
PCM 90, so processed audio returns immediately when
Bypass is turned off.
Bypass: Completely bypasses the PCM 90, passing unproc-
essed audio directly through to the outputs.
To assign an external controller to perform the selected bypass function, press
Load/ to display Bypass Src. Use ADJUST to select a footswitch or any MIDI
controller (or Off). Once a source is selected, it will perform the same function
assigned to the front panel Bypass button.
1.4 Pgm Bypass
This control allows you to determine the behavior of the PCM 90 when a new
effect is loaded. The choices available are: AllMute or Bypass.
1.5 Mem Protect
The PCM 90 provides a memory protection feature to prevent accidental
overwriting of your stored effects. When this control is set to On, pressing the
front panel Store button will cause an error message to be displayed. The PCM
90 is shipped with the Memory Protection function turned Off.
1.6 Auto Load
This control allows you to choose whether PCM 90 effects will be loaded
immediately when selected with SELECT and the Up and Down buttons (On),
or whether they will require a press of the Load/
Lexicon
button (Off).
