Yeah, I am hoping that the bug with the Gated Seq in stack mode will be addressed (Ticket #48090). It definitely would allow greater expansion of the Rev2's voice modeling capabilities and rhythmic sequencing/modulation capabilities.
I'm guessing they are nearing release of a new product, and that's why we haven't seen a firmware update... Not sure if they'll be addressing any of the feature requests in that very good thread, but hoping we'll at least see bug fixes.
Hopefully, we'll hear some news on this soon, and a new synth to drool over too.
