I’ve never yet had Scaler bring down my DAW, although the vast majority of the time I am using Live. However, I do have Cakewalk (latest version) which I do use from time to time, but have not experienced any problems with this.
I’ve just searched the posts for all those containing the word ‘Cakewalk’, and there are 3 which mention a crash .
There were several reports relating to dragging and dropping in Cakewalk, reported by @Trankonia, @RedFox, @Slharder and others.
However, there are more crash reports in other DAWs (including Live) than Cakewalk, but that probably is simply a result of the distribution of DAW usage here. They were not always for the same reason.
I’ve been a Cakewalk / Sonar user for 20+ years after buying v2.1 on floppy discs (!) and they were very late to the VST party, having instead used their own DXi approach. It is therefore conceivable that the lack of stability you mention may have some bearing on that. although you say other VST’s have not given any problems.
I’d be happy to help by running test on my machine to try and replicate any repeatable crash scenarios you can specify Hopefully it’s possible to do this as the crashes occur with Scaler alone, so it is some Scaler / Cakewalk interaction. If I can’t reproduce them, then that might point to some specific Scaler / machine interaction. Let me know if you want to do this.
