I contacted a source about the Discover series[Discover 5 is five octaves, expect a 7}.He told me Roland is very vague[secretive]..It indeed may have styles and arrangements on board..Possibly dropping the old SC55 and CM [mt32 map] banks in favor of the G800, G1000 and VA series banks[including the "Scat" patch]. I am told they are still in proto type design and not available yet..When I find more info I will pass it on..Fran
