Why would anyone choose the Akai OS over JJ?

I agree, the chopping and GPE are to die for. I went back to Akai OS for a few hours one day to see if JJ was truly "better" than the AKAI, and oh... god... shit was like night and day. JJOS killed the akai in productivity.

As others stated .. JJ will help your productivity and beat making process, but if you cant make a beat in the first place it wont help you. Garbage in == garbage out.

Yeah i did it, installed the free one and the 10 mins later bought the OS1 I believe... I cant compare akai to this one because i didnt really use akai's but JJ OS is nice and easy to use
