However, to be fairly honest: Rack Extensions are not VSTs.
One may argue that Rack Extensions is the VST part of Reason. While it has been stated back in days of Reason 5, Reason will NEVER adapt to the technology of VSTs. So with that in mind, I thought it would be a nice idea just to throw in a list why Reason should not be the DAW for you (just to save you some time in case you think this program can handle everything). However there are times people point out why Reason isn't the DAW for everyone (since serious, it isn't for everyone.). However there are moments that I go back to other DAWs so I can compare thing, spot the weaknesses and 'code' my own stuff back in to Reason to get similar things done that other DAWs can do to. To be honest, I like Reason for what it is.
I would just write down a list of items why Reason will never be the DAW for you (in case this question comes to mind). Or people calling out that Reason kind of sucks in a general context. Since I have been seeing a wide range of 'threads' (eg: forum posts) about why people would leave reason.
