I've just been exporting all my ACT presets for import into my laptop install. I did mention how to do this in the
Complete Sonar X2 video but didn't do a step-by-step video for it. - I had to try and stay under 10 hours somehow...
Anyway, it applies not only to ACT presets but presets for VSTs and other plugins too. So if you just want to back them up or transfer them to another install, this may well help... oh and it's free.
