I just like to report that I can only use one Aalto that my cpu is going up to the stars.
I read people that with similar Mac can get 20 or more instance of Aalto.
Any idea, any help.
MacBook Pro 17" I/7 2.2 GHz intel Core.
16GB ram Yosemite 10.10.5
Ableton Live 9.7.5
Can you look in Activity Monitor and tell me what Live's CPU use is first with one instance of Aalto, then with Aalto disabled? Then I can tell you if it seems reasonable.
Your system should do well with Aalto. CPU is the only really important thing for Aalto, disk and memory won't affect it much.
