This also happens in ext2: the memory usage keeps on growing if you switch patches, it doesn't seem to unload them. I checked this using the windows taskmanager.Muon Software Ltd wrote:CMplay is based on our Tachyon Engine which is very stable, well-tested and used in numerous commercial products. It is more likely that the samples *are* clearing from RAM but something else is at fault that might be specific to Sonar 7. Any chance of a screenshot of that error message? have you run Resource Monitor while loading/unloading patches?However, with Sonar 7 on my Vista 32-bit machine, the samples loaded into RAM never clear. Even if you specifically select "delete from memory", the samples stay loaded into RAM. So, if you audition a lot of patches, you start to run low on RAM. Imagine my shock when my 4GB of RAM machine told me there was no space in memory! Needless to say, this has made it unuseable for me. This might not be true for everybody.
I find browsing patches a bit awkward too: they're all three submenu's deep for no reason (there's nothing else at the top levels)
