"Quotes from manual (1976):
"With its ease of operation and high reliability, your ARP Odyssey
can produce an enormous variety of sounds in live performance."
"Its two voice, 37 note keyboard has a nine octave range..."
"And, of course, the famous ARP filters and oscillators give you
drift-free accuracy for professional-quality recordings.""
