Doepfer PK88 Midi Masterkeyboard (new version with USB) - Manual (Page 4)

PK88/USB User's Guide - Page 4
The PK88 requires a single or double foot switch with contacts "closed at rest". If a switch with contacts
"open at rest" is used, the functions are reverse !
Please pay attention that some Midi expanders do not support the Midi controller #67 (Soft pedal). Sustain
(#64) is recognized by nearly all expanders. Please refer to the user's guide of the expander used if both
controllers are supported.
The double foot switch is not included with the PK88 and has to be ordered separately if required. The
PK88 will work without the double foot switch, although the functions SUSTAIN and SOFT PEDAL will not
be available to the user in that case.
7. Connection of the Foot Controller
Located on the rear of the keyboard case is a socket for connecting a foot controller. It is labelled Foot
Control. Do not connect the foot controller unless the PK88 is switched OFF. The controller transmits
VOLUME (Midi controller #7). A suitable foot controller is e.g. the Doepfer FP5. If another foot controller is
used it has to be the same value (10k linear) and has to be connected as described in the appendix.
The foot controller is not included with the PK88 and has to be ordered separately if required. The PK88 will
work without the foot controller, although the VOLUME function will not be available to the user in that case.
