Connecting External Devices — Step up with MIDI
Please read this section if you are planning to use the pt-
2000’s MIDI functions, connecting it to another MIDI device.
When connected to one of Roland’s MT Series devices or
other such instrument, you can play the many MT Series
internal tones with the pt-2000’s keyboard, as well as record
the performances.
Using MIDI
■ About MIDI
MIDI, short for “Musical Instrument Digital Interface,” was
developed as a standard for the exchange of performance
data between electronic instruments and computers.
The pt-2000 is equipped with MIDI connectors to allow such
exchange of performance data with external equipment and
devices. Connecting the keyboard to other devices with these
jacks provides you with an even greater variety of ways to
use your keyboard.

MIDI Out Connector
Performance information such as the output from the
keyboard or pedal is sent out here to the MIDI connectors of
external equipments.
MIDI In Connector
MIDI messages sent from connected external equipment are
input here, then pt-2000 can output sounds, exchange tones,
and perform other operations.
■ Sending and Receiving Program
Change Messages
When you press the pt-2000’s [Piano] button or [Tone] button
to change tones, a Program Change Message with the
corresponding Program Number is sent via the MIDI Out
connector. Furthermore, a Program Change Message
received via the MIDI In connector changes the tone to the
one with the corresponding Program Number.

Switching Tones with Program
Change Messages
Here, with the pt-2000 connected to an external MIDI
sequencer, when recording and playing back songs, if
after pressing the sequencer’s Record button to start you
press the pt-2000’s [Tone] button and then begin to play,
a Program Change message for that tone is recorded by
the sequencer. When you then play back using the
sequencer, regardless of the pt-2000’s mode, the tone is
changed in accordance with the Program Change
messages recorded by the sequencer, allowing you to
play back with the tones used during recording.
In addition, Program Change messages from tone
changes made while the recording is in progress are also
recorded, meaning you can also record songs with tone
changes made during the performance.
