Chapter 1. Overview of the JP-8080

How the JP-8080 is Organized

The overall structure of the JP-8080 is as follows.
MIDI connectors
The JP-8080 has two MIDI IN connectors (IN/REMOTE KBD IN) and one MIDI OUT connector.
Operations performed on an external MIDI device connected to REMOTE KBD IN will be handled exactly
in the same way as when JP-8080 controllers are operated (including test playing in preview mode).
This means that when an external MIDI device is connected to REMOTE KBD IN, the following things are
possible. (These things cannot be controlled from MIDI IN connector.)
Playing back arpeggios (p.90)
Recording/playing RPS patterns (p.92, 94)
Recording controller messages from an external MIDI device to Motion Control (p.100)
Sound generator
The sound generator is the section which produces the sound. It receives note messages from an external
MIDI device, and produces sound in response to these messages. In Preview mode, sounds can also be
played by pressing the BANK [2], [3], [5]–[7] and NUMBER [1]–[8] buttons.
About maximum simultaneous polyphony
The sound generator of the JP-8080 can produce up to 10 simultaneous notes (voices) when the Voice
Modulator is off, and up to 8 notes (voices) when the Voice Modulator is on. If incoming messages request
more than this number of notes at any one time, the newly received notes will take priority, and the oldest
sounding notes will be turned off one by one. This means that some of the previously-sounding notes will
be interrupted. Please be aware of this when playing sounds which have a long decay, or when using RPS.
Sequencer
Arpeggiator
The arpeggiator plays arpeggios in response to note messages from an external MIDI device.
In Preview mode, the arpeggiator can also be controlled by pressing BANK[2], [3], 5]–[7] and NUM-
BER[1]–[8].
