Currently you have to be very careful when manually editing the bpm/grid in EP. The BPM will always stay constant… Even when you edit the grid!! With most other software, the bpm updates as you adjust the grid. This DOESN’T happen in EP. What actually happens is that EP tries to warp your grid to the bpm number shown for that track. If you’re not careful, you’re track will suddenly (and sometimes drastically) speed up/slow down, wherever you changed the grid & set new beat markers. If you want to manually edit the bpm, you need to type the correct Bpm into the window next to the waveform, then shift (not expand/contract) the waveform to line up with your downbeats. This is my biggest gripe with the EP software!!
