As far as I'm concerned, the current code has always been a bit useless -- a consequence of someone (was it me, back in the day? not sure... if so I apologise) doing what seemed obvious without giving it enough thought. The main reason it has never changed is just inertia based on there already being sessions out there using the existing behaviour. One thing I'd say though is that this sort of thing really must be part of the saved document, not just part of the application settings. There could *be* an application setting, but it would have to be a default for new documents rather than a fixed setting for every document. It's not really OK to have sessions changing their mix balance without warning when saved and reloaded. At the very least, RG should know enough to be able to warn when a session is reloaded with a different pan setting (or when a session made before the setting was added is reloaded with a setting different from the former default). > From what I've read, I'm not sure that OdB, -3dB, or -6dB setups would be useful for what I need to do. I *think* that what's usually referred to as a -3dB law is actually what you have -- i.e. -3dB in power rather than voltage. (as 10^(-3/20) == 1/sqrt(2)) Probably should check what other software thinks though, which I can't readily do just at the moment. (However, it should attenuate in the centre rather than boost at the edges -- otherwise you can load a normalised file, pan it, and it clips.)
