u Damper Pedal The damper pedal functions in the same way as a damper pedal on an acoustic piano. When the damper pedal is pressed notes played have a long sustain. Releasing the pedal immediately stops (damps) any sustained notes. i HEADPHONE Jack A standard pair of stereo headphones can be plugged in here for private practice or late-night playing. The internal speaker system is automatically shut off when a pair of headphones is plugged into the HEADPHONE jack. o OPTIONAL IN L/R and OUT L/R Jacks The Optional Out jacks can be used to deliver the output of the PDP-300 to an external keyboard amplifier or stereo sound system. On the contrary, the Optional In jacks can be used to reproduce the output of another instrument such as cassette tape recorder through the PDP-300's built in speaker. !0 MIDI IN, THRU and OUT Connectors The MIDI IN connector receives MIDI data from an external MIDI device which can be used to control the PDP-300. The MIDI THRU connector re-transmits any data received at the MIDI IN connector, allowing "chaining" of several MIDI instruments or other devices. The MIDI OUT connector transmits MIDI data generated by the PDP-300 (e.g. note and velocity data produced by playing the PDP-300 keyboard). More details on MIDI are given in "MIDI FUNCTIONS" on page 8. 5
