PCM 91 Tempo 0.2 Source set to MIDI

The configuration below shows the MIDI connections for controlling the PCM 91
simultaneously with MIDI Clocks from a sequencer, and messages from another
MIDI controller. Note that the controller is set to "local control off" and the
sequencer is set to "echo input".

Two PCM 91s can be slaved together by connecting a cable from the MIDI OUT
jack of the master to the MIDI IN jack of the slave. Additional PCM 91s can be
slaved to the master by connecting a cable from the MIDI THRU port of one slave
unit to the MIDI IN port of the next unit. All of the PCM 91s must be set to the same
MIDI channel and Device ID.
