I want to note here and now that I have almost zero experience with audio related software, and as such this review should be viewed as a beginners opinion of the software.
Ohm Studio looks nice, and has a "slick" ui. The biggest issue I have with the ui would be that it can get complicated/ cluttered with stuff pretty fast. Overall though I think Ohm Studio does a good job with its introductory tutorial, and gives you a pretty decent idea of where to "start" using the software. Ohm Studio to me feels more focused on community projects, and the "fun" side of making music, than the "business" side, you will find alot of basic features and fun things to do with open projects that you can work on with strangers/ friends but you will find less "serious" or complicated features that more professional music/ audio tools incorporate.
Overall I like Ohm Studio, and think its a pretty good music software. The fact that its free is also a pretty big positive considering its good enough to charge for. The Majority of the above review is based on my initial opinion, I may be missing something important but overall I think I described Ohm studio accurately. You should give it a try, you may like it. Especially if your "good" at, well, pretty much any musical instrument.
