Buyer beware: this is still a beta.
I am absolutely disgusted by Image Line for releasing this atrocity and calling it a 1.0 version. Its simply unprofessional, and paying full price for a half-baked app is one of the most frustrating experiences Ive had with the app store. If I could get my money back, I wouldnt even have to think about it.
Heres the thing. I heard great things about sequencing in FL Studio Mobile HD, so when I loaded up the app for the first time, I immediately tried to figure out how to connect it to the rest of my iOS synth rig. Simply put, it cant. If you search the forums, you can find a thread listing all of the things that will be available in future updates, including many features listed as in the description here on the app store. I hesitate to call it a bait-and-switch scheme, but I truly feel swindled.
For my workflow, which revolves around core MIDI and inter-app audio, FL Studio Mobile HD 3 is absolutely useless. Theres no IAA support, no core MIDI or network MIDI routing, and theres only minimal Audiobus implementation, which I didnt even bother to figure out how/if it works. Ableton Sync? Forget it. Unless youre okay with being limited to the built-in instruments, this app is worthless.
Now, about the user interface... To put it mildly, Im not a fan. Granted, the FL Studio Mobile 2 UI looked like the kind of thing Id expect from a PC program circa 1996, so I respect the decision to go with a modern streamlined approach. Folks, this isnt it. They overshot minimalism so far that the user interface is just plain annoying.
The menus are counterintuitive and all of the controls look the same (and terrible). In fact, the minimalist design was doubly frustrating for me, because I kept trying to figure out where the features I need and expected to find were hiding. I literally wasted three hours trying to figure out what I was missing before finally figuring it out. I believe I thoroughly expended my allotment of profanity for the rest of 2016, and Im going into 2017 with a massive f$#k! deficit.
My conclusion: Id been hoping for an all-in-one electronic-music-production DAW for my iPad, and what I got was a platform that looks like it was designed by an intern loaded with a bunch of vanilla instruments that dont impress me. I couldnt be more disappointed. Ill keep the app on my iPad, and I will check it out as the developers actually finish the product, but I simply cant imagine that the improvements are going to make me want to switch from a DAW that looks and acts like a DAW to this total failure. Sorry Image Line, but you did this to yourselves.
