I was looking into switching over from Logic Pro to Studio One, but I don't play in the standard 440 Hz tuning. In Logic, it allows you to globally change the concert pitch tuning (in my case 432 Hz) to all software instruments within your session. From what I can tell there isn't anything like this in studio one. The work around would be having to do the change in concert tuning within every single software instrument plugin added within the session (if the software instrument plug in even has that capability). I hope studio one will implement something like this soon.
