CONTROLLER AUTOMATION
For applications where it is desirable to "automate" changes made
to PCM 81 effects with its own controls ( ADJUST knob, Foot Pedal,
Footswitch 1 or Footswitch 2), we recommend assigning the
controllers to MIDI destinations and recording the changes with a
MIDI sequencer (see Control Mode parameter 3.5, MIDI
Destinations).
RESET ALL CONTROLLERS
The PCM 81 recognizes the “Reset All Controllers” message. When
received, all patched parameters are reset to their stored values.
Patched parameters may also be reset from the PCM 81 front panel
—Control Mode parameter 3.0 (the message will be transmitted
from the PCM 81 as well).
MIDI CLOCK AND CLOCK COMMANDS
The PCM 81 recognizes MIDI clock messages when Tempo Mode
parameter 0.2, Tempo Source is set to MIDI. Any Delay or LFO
parameter set to display tempo values will be synchronized to the
tempo of the incoming MIDI clock.
MIDI Clock and Clock Commands are also available as Dynamic
MIDI patch sources. The value of MIDI Clock when used as a patch
source is a linear scaling of 0 to 127 (0 = 40 BPM and 127 = 400
BPM). The value of Clock Commands when used as a Dynamic
MIDI patch source is 1 for START and CONTINUE and 0 for STOP.
PCM 90 COMPATIBILITY
The PCM 81 can receive MIDI data from either the PCM 80 or
another PCM 81. It can also transmit certain messages in PCM 80
format. (See Bulk Data Dumps and SysEx Automation.) This allows
most data to be exchanged between the two products, with any
format translations handled automatically by the PCM 81.
DYNAMIC MIDI
The following MIDI messages are available as Dynamic MIDI patch
sources:
• MIDI Controllers 1-119
• Pitch Bend
• After Touch (Polyphonic and Channel combined)
• Velocity (Note On)
• Last Note
• Low Note
• High Note
• Tempo (40–400BPM is converted to controller range 0-127)
• Clock Commands
These MIDI messages are also available as threshold sources for
several Modulation parameters: AR Env, Latch, Sw 1 and Sw 2.
They may also be used as a tap source for controlling Tempo.
