Faderport 8 is real nice with Studio One as well so if you are a Studio One and Mixbus user it is a very good choice. Harrison have integrated it well it seems.
I will hold off for the moment on 32C being pretty involved with Mixbus anyway and have plenty to go on with especially with ver 4 and all. Having 32C V3 is a great way to get into it too I am finding. I am sure they will make it tempting again at some point to upgrade 32C V4.
Being in the monthly club is a good idea especially for those who are using it on a pretty regular basis. I am not at present, mainly only for mastering and some stem mixing. Mixbus is handling that real nice for me now anyway. I can see why many seem to like it. It is nice to use. It is worth the money I agree. If I suddenly get flush I will get it anyway!
It would be good to know what doing a full project start to finish is like on Mixbus. I am not at that point right now but some here maybe.
