The Jupiter-8 is an 8-voice polyphonic synthesizer with a 61- note keyboard. The Jupiter was Roland?s ?flagship? synth and one of their best sounding analog instruments with its airy, transparent sound. Roland took the best features of the OBX and Prophet-5 and then added a few more of their own to create a true classic. Wonderful, shimmering, string sounds and punchy brass are no problem for this versatile analog monster. 514 Megabytes.
