So it seems that this is not going to be resolved at all despite all the requests. I use also Reason and I'm ****** of already by the fact that I need to upgrade it in order to use Rewire with Studio One 4. I play with my band tuned at 435Hz and normally compose music in Reason at 432Hz. Ignoring this request is ridiculous, so many people asked for that to be added and still no direct answer from the project/development manager or from whoever is in charge of all that. We are left praying that one day it may arrive. You claim you listen to the customers/users, how so? I have a ton of features that I'm not going to use ever, but hey, you have no time to add GLOBAL/MASTER TUNING after how many years of requests?
This is a joke, for real!
