Info
The PCM 81 offers an extensive set of informative
display messages which can be activated from the front
panel. If you want to know more about the function of
a particular button —without actually executing any
action — press and hold the button down. While you
are holding down the button, an explanatory message
will appear on the display.
Control
• Press Control to access system parameters,
MIDI controls, and global control of parameters
such as Mix, Tempo, and Bypass type.
Tempo
• Press Tempo to set tempo-related values that
affect the delay time and LFO rate parameters
of the currently running effect.
Tempo
• Any PCM 81 delay parameter (as many as 10 in some effects) and any time-based modulator can
be individually assigned an absolute time or tempo value.
• You can set delay times in milliseconds, or in a ratio of echoes/beats which are linked to tempo.
When you change tempo, the delay times will change to maintain the same rhythm at the new
tempo.
• To set PCM 81 tempo rate, press Tempo. Use SELECT and Up and Down to locate matrix position
0.0. Turn ADJUST to select any Tempo Rate from 40-400 BPM.
• Or, press Tap twice in rhythm to establish the tempo rate you want. Tap is always active, allowing
you to change tempo on the fly.
Note:
You can set and display delay values in units of time, or with tempo values. Whenever a delay value is
displayed in Edit mode, press Up and Tempo simultaneously to toggle these two options.
