Several users and I have been running Aalto on Ableton Live 9.0.5 since its release. One person reports a repeatable problem that forces Live to quit with its "serious error" dialog. So if you are working with Aalto and a previous Live version, I recommend that you do not update to 9.0.5 right now. Stay tuned for news of an Aalto update.
The new Logic Pro X seems to be hosting Aalto well without any problems.
That’s the Live and Logic compatibility update.
