First … it’s true I probably not use ReWire correctly.
But it would be usefull to open and work directly on data rather than on flow : at least the ability do send and receive data to and from an application (like it is actually possible in Cubase & Wavelab) ; at best the ability to open Dorico in replacement of Cubase Score Editor (as an option if you own the 2 applications) or to open Wavelab within Cubase as a complement of the (very usefull) cubase audio editor without an export/import and with the benefit of a single application (and the ability, for example, to use the history in all steps - not only mix console - and to save the history).
SteveInChicago : Is this what you said by “sharing selections” ?
Minimalist : do not hesitate to correct me if ReWire should be my “go-to” option … as soosn as Dorico will include ReWire
