At this time we strongly advise you NOT update to Big Sur or MainStage 3.5.
Our advise is based on experience with a large number of users encountering a wide variety of hardware compatibility related issues every year when a new MacOS is released.
We recommend that you look to the manufacturers of the hardware you rely on to see them give the all clear for Big Sur before you update.
Does MainStage 3.5.1 fix all bugs from 3.5.0?
No! Unfortunately, in our testing it hasn't. MS 3.5.1 still has a couple quirks that we’ve seen, including a graphical bug that causes all vertical faders to be the same color regardless of their intended color and some issues with the new Sampler plugin incorrectly loading saved volume states for converted EXS24 instruments. We’ve made MainStage’s developers aware of both of those issues as well but they have not yet been addressed as of 3.5.1.
For those of you who have not yet updated to 3.5 at all, we still recommend that you stick with 3.4.3 or 3.4.4 for live performances while the stability of 3.5 is given more time to be proven. If you want to update to 3.5, then make sure to backup your MainStage 3.4 build first.
For anyone who is currently on 3.5.0, we strongly recommend that you:
- First create a zipped backup of 3.5.0: Click here to learn how to do that.
- Then, go ahead and update to 3.5.1.
What about Sunday Keys and Sunday Sounds' products specifically?
Since our products largely work within existing software like Ableton Live, MainStage 3, and Omnisphere it's best to look to the manufacturers of those softwares before updating.
Ableton and Spectrasonics have both advised their users hold off on updating.
Since Apple is the developer of MainStage 3 it's highly unlikely that Apple will encourage their own users not to update, but in our experience MainStage is not always immune to initial OS related bugs.
For this reason again, we recommend you wait to update to Big Sur.
Specific to Sunday Keys and all of our products, we'll also be working with the release build of this new OS to make sure there are no issues introduced by Big Sur.
In the meantime, if it ain't broke, don't fix it!
If you have a compelling reason to update and just can't wait, make sure to do a full Time Machine backup of your system before doing so, as that will allow you to revert back to your prior OS if you run into any game-breaking issues.
As always, we strongly advise against using Apples "Auto Update" feature.
We will communicate any issues that early adopters run into as we are made aware of them, but again we recommend that you keep checking with the manufacturers of the software you use to see when they give the all-clear. We will also be sure to let the community know should we become aware of any prevalent issues.
