yeah I had acid for years, I never took it serious, until I tripped up and found out you can use it as an MP. I was like WHoa, and it's easier than the mp, you can actually see what your doing, cause listening to what your doing, takes a while to get used to. And if you fuck up with the Mp, you gotta start over with the track. Acid you can just slide it where you want it, kinda like your sister...
