Initially Sand seemed to run well on my 2016 air2 (64gb) but recent updates whilst fixing issues and adding features have seemed to make the app more cpu and/or memory hungrey. A session that I created on an early version has now become unplayable. Any navigation/edit or opening up of an avu3 plugin or effect plugin whjust playing causes crackles sound dropouts and lags. Also I noticed buffer size as switched from 512 to 1024 in settings. Don't know if this has something to do with it. Tried changing back but didn't seem to make a difference.
