without the FX being reset, so we can quickly get a spectrum display in Span of the whole song or selected time selection? The idea was first posed by ashcat_lt: I also posted this in the scripting department. As it is right now, you have to play a song all the way through in order to get a spectrum analysis of the whole song during the mixing and mastering process. Or if you want to check out one or more tracks over a period of time. Being able to quickly play the whole song, or parts of it, would save a great deal of time. Here's a video somewhat explaining my mixing and mastering process in Reaper.
