I've been using Fruity Loops for click tracks. Doing odd sig's is possible, but it eluded me so I'm looking for something else. $50 is a bit much for just making a click track though. But maybe not, if there was an easy to use program that just does click tracks, with an easy interface, I'd buy it.
Such a simple program you would think there is something out there half decent - that exports as a wav file (for re-importing in the software multitracker on its own channel) - *important* feature, to me anyway.
If you find something, let me know.
