Disclosure, I is noob:)
Cakewalk is now free. It used to be a program you used to have to pay for, but through foreign corporate acquisition, you can get it as "Cakewalk by Bandlab", free. You'll have to set up a Bandlab account, and then the DAW is yours. LMMS is also free, but it's VST capabilities are horrid. However, it's built in synths and soundfont support are awesome. There are VST's for SF support in other DAWS, but LMMS seems to do it the best and most consistently. You can always use both:) If you don't like them, you are out zero dollars.
VST's are important, that's where you'll get the most of your sounds, and there are many good free ones out there for beginners, like us:) It's great we live in a time and age when we can get our feet wet for free. I've not paid a dime for anything, and I think my stuff keeps sounding better and better through practice with the tools I have. Full disclosure, I'm not posted on OCR yet (I hope it happens), but I'm working on it, and I have made it a mission to do so without paying anything, so that everyone else knows that it can be done for free, also.
TL;DR. You can try Cakewalk and LMMS for free, and they both have their strengths.
