I've been using TR5 for quite a while, with few problems and pretty good results. However, a recent drive issue caused me to replace one of my hard drives - not the system one with Windows etc on it, a purely data drive on which all my music projects were stored. When I attempted to continue with a remastering project that I'd been halfway through, I hit a problem - neither Cubase nor T-Racks would output any sound. A week of driver updating, uninstalling and reinstalling of the audio interface (MOTU Ultralite Mk3 Hybrid) and trial & error, and I discovered that the problem was the ARC2 plug-in, which was reducing all the volume to zero. Having solved this issue, I'm back to the remastering project.
However - before I had the issue I could vary the volume of the output from T-Racks while mastering using the standard Windows volume slider. This was great - it meant I could continue working without upsetting neighbours. Since I got everything working again, I have absolutely no control over the volume of the output from TR5. It takes no notice of anything - INCLUDING the master volume control on the audio interface! What the heck am I missing?
