Re: Sequencer improvement
I use the Matrix very liberally, but sometimes you simply have to make a sequencer track. And that's where the sequencer improvements that arothman mentioned below would come in handy.
I just hadn't seen this particular feature request posted in a very long time.
I'd be very surprised if the next version of Reason doesn't have most of those oft-requested features that would make the Reason sequencer (IMHO) perfect.
