ReTracker - The power of a tracker inside the Reason-rack
This suggestion will probably get shot down very quickly, but here goes...
I'm having wet dreams of a stripped down version of Renoise (or any other tracker, but I use Renoise and would prefer this) for the Reason rack. It should have all the main features as the full version, including native DSPs and synths (but without VST and midi capabilities). It would act as a hybrid Matrix on steroids, sampler/Redrum/Dr.Rex/Recycle-unit.
When you flip it around you'd find several audio ins/outs, aswell as several CVs ins/outs to hook up and control other Reason-units.
Attached is a mockup of how it would look in the rack.
