For what it's worth, If I remember correctly, when I drop markers into files using Sound Forge they show up in Qlab. Makes it nice sometimes when you want to line things up as I find it easier to really zoom in and be accurate with finding zero crossings in Forge.
Of course I'm
working in PC land not Mac OS, except to run QLab. So I have no idea if the Mac OS version of Forge does the same thing or not.
I don't think it would be worth the extra step just to put in markers but I do probably 3/4 of work in just Sound Forge so it makes the most sense for me.
