Many thanks ! Interestingly, but not suprisingly, the I7 uses the same R8A02021ABG chip as the GR55, JDXi, BK9 and proabably many others SN based products like the JD/XA, JP50/80, FP etc.. lines. This chip is for SN,PCM.. and Roland uses the ACB chips to recycle and bring out new variations in the Aira/Boutique line of products. Those must be the two pillar core hardware of their bread and butter synth's income. It may be a while before Roland invests in new core logic hardware for next generation SN /ACB lines while they exploit the Roland cloud. in other words, a while (if ever !) before seeing anything really new. It's milking the cow kind of time after a bit more active period between 2014 and 2018. Now that all the historical product are emulated in hardware and software, maybe they are thinking about something revolutionary ? A poly-AT 76/88 keys controller I hope, even that is historical as well.
