• In the brief time since its introduction the Jupiter 8 has become the most popular polyphonic synthesizer among session players and recording groups.

The Jupiter owes this popularity to an outstanding array of features, a reputation for durability under arduous conditions, and most of all because it delivers unsurpassed sound.

•The key to the JP-8's unsurpassed performance ability is an advanced computer assigned keyboard which allows more flexibility and control than ever before. The five octave keyboard can be used in three different Key Modes, Whole, Dual, and Split. Whole mode gives the whole keyboard a single patch sound across all eight voices. Dual provides a layered sound with two patches sounding with every key depression. Split mode can give one side of the keyboard one patch sound, while the other side has another sound. On newer JP-8's this split can be moved to any location on the keyboard and retained in the synthesizer's patch preset memory.

•The Jupiter 8 gives the user Four Assign Modes including; Solo, Unison, Poly 1, and Poly 2. Solo stacks all sixteen oscillators on a single key depression which makes the keyboard monophonic but very "thick" sounding. Unison places as many oscillators as are available to a single key depression while retaining polyphonic sound. Poly 1 and Poly 2 differ only in the length of release time of the last note played.

•The Jupiter 8 keyboard computer also provides an Arpeggio section which can be used for sequencer like lines on either the whole keyboard or the lower half only,
leaving the upper section free. The Arpeggio can be controlled by means of an External Trigger.

•Sixty-four patches can be stored in the Jupiter's memory and eight Preset Pairs can also be stored. Stereo Outputs, both high and low impedance, guarantee the Jupiter's sound will be faithfully reproduced on stage or in the studio. DCB Digital Interface allows connection of the Jupiter to products like the MC-4 MicroComposer and the CMU-800 Compu-Music. A MIDI to DCB interface will soon enable the connection of MIDI instruments to the Jupiter.
