can somebody possibly tell me how to do something clearly easy in ableton

how do i gradually increase the tempo of an entire track in a straight line

Click the unfold track button on the Master channel in arrangement view, select Mixer in the first parameter box underneath, then click Song Tempo in the parameter box underneath that, enter the values for your minimum and maxiumum tempo, then draw in the parameter.

I'm pretty sure you can draw automation for BPM in the master track in arrange.

I don't think you can do it in session beyond assigning bpm to a knob and messing with the min/max settings then doing it live.

thanks very much

just to be cheeky before i bugger off, whats good in the way of boxes of midi nobs and sliders thats cheap? i cant fit my midi keyboard up here and i find the keys useless anyway, cheers if anyone can drop me a suggestion
