13. Expression Input and Side Roller
The DPC-5 Gen3 is equipped with a dedicated input jack that may be assigned to a variety of control functions. Depending on the
configuration of the Expression Input, either an expression pedal using a 10k-100k potentiometer or a momentary normally-open
footswitch may be connected. If an expression pedal is used, the connection should be made with a tip-ring-sleeve / TRS / stereo
cable. Tip = 0-3.3V, Ring = 3.3V, Sleeve = GND.
Starting with firmware version 1.01d the Expression jack may be used as an additional MIDI output, similar to the MultiJack. Set EXP =
MIDI in the DPC-5 setup menu to enable MIDI communication from the Expression jack. Connect to your Chase Bliss pedals with an
MJ-CBA cable, or to an Empress or Meris pedal with a standard patch cable. You can also use an MJ-5P cable to connect from the
Expression port to a standard 5-pin MIDI input.
The DPC-5 Gen3 may also be equipped with a side roller potentiometer as a factory option. In previous versions of the DPC-5 series,
the side roller shared an input channel with the external expression input and the two could not be used simultaneously. The Gen3
improves upon this arrangement by assigning each input its own dedicated channel, and each may be assigned separately to any
combination of destinations.
To review the Expression Input or Side Roller options please consult the EXP and ROLL options in the Setup Menu. Note that the E CH
and R CH menu options determine which MIDI channels each input will use for sending messages.
Example: The user has connected a Strymon Timeline (B) and Mobius (A.) The user wishes to have the side roller control the looper
volume level for the Timeline and for the expression input to control the expression parameters for both Timeline and Mobius.
The menu options should therefore be set to EXP = EXPR, E CH = AB0, ROLL = LPR, R CH = 0B0. This sets the expression input to
expression and allows it to send to the A and B devices, and the roller to send looper level for the B device only.
