MIDI Operation

SysEx Automation Automation

The PCM 80 will transmit SysEx automation messages when Control Mode parameter 3.4, MIDI Automation is set to On. All changes made by front panel operations are transmitted as PCM 80 SysEx messages. This is intended primarily for use by editor programs and in configurations where it is desirable for one or more PCM 80s to be slaved to a single PCM 80 acting as a master. The current mode (Program Banks, Register Banks, Edit, Control or Tempo) of the slave does not follow the master, but the actual parameter values do. (SysEx automation can also be stored on a sequencer and replayed in real-time. As a general rule, automating more than two or three SysEx program changes at once is not receommended.)

The PCM 80 can receive SysEx messages when Control mode 3.7 MIDI SysEx is set to Receive On. Note that when using SysEx automation, the device of the receiving PCM 80 must match the Target ID of the transmitting PCM 80.

The Target ID setting can be adjusted fropm Control 3.4 MIDI Automation. It is selected by pressing Load/✱ after setting Automation to On. The default setting for the Target ID is All.

The Device ID setting can be adjusted from Control mode 3.7 MIDI SysEx. It is selected by pressing Load/✱ after setting SysEx to Receive On. The default setting for the Device ID is 0.

Controller Automation

For applications where it is desirable to "automate" changes made to PCM 80 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 80 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 80 front panel —Control Mode parameter 3.0 (the message will be transmitted from the PCM 80 as well).

MIDI Clock and Clock Commands

The PCM 80 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.
