Update is not good

I spent a ton of hours using the previous version, I gained a large soundcloud following. Ive spent a lot of time trying to learn the new setup and gave it a fair chance..and now I dont understand the app and cant figure out how to remake the sounds that I made previously. Im sure the sounds are higher quality than they were previously... but was it necessary to change the entire format? They shouldve kept the same setup. Now all of my tracks sound like crap because the update messed them all up. It would be really nice if I could downgrade back to 2.5.4 or get a refund so I can invest in a different program.
