You already have this in Media Explorer.
yes i know, but i was talking about changing the tempo x2 or /2 for the whole project, in the arrangement window.
Actions to double or half the current playrate of a project or item would be great. :)
I wouldn't use that, as doubling or halving the project tempo would lead to either too high or too low values. (120bpm would land on either 60bpm or 240bpm) Maybe good for music practicing?
I wouldn't use it for projects much I don't think. But I'd use it on items daily. Guaranteed.
