Not sure If your used to software only or have external controllers, you may want to start smaller, but I don’t know how dedicated/sold you are on learning the OT.
I despised menu based instruments/hardware for a while but elektrons abilities sold me. If you haven’t worked with any hardware as of yet I’d say the OT will be easy to get your money back if it’s not for you as long as you buy it used. I started w/DT and it was a sinch to learn. OT just has way more options and some things like sampling, more steps for set up.
Other than there just being so many things to learn it’s not difficult, but I don’t know what your approach to recording and putting together a track is so you may be working in a way that is in a different approach but since the OT is so modular you have many ways to approach the same thing. Have fun!
