The original Orchestra was very limited but still a very characteristic instrument for its time.

It produces its sounds from a divide-down oscillator network and therefore has 49-note (unlimited) polyphony.

Although it contains 4 sections of presets (Brass, Strings, Reed and Piano), which each contain two sounds, the only parameters that can be edited are Vibrato (LFO), Brilliance (for the Brass, which also has a separate 'Brass Attack'), Attack and Decay.

This version replaced the Reed section with an Organ one; however, aside from that the synthesizer was almost identical.

It also had a pitch bend function which was surprisingly never included with the first version Orchestra.
