I doubt there are, but I was just curious, since you hear about all of these mobile apps for learning keyboard, (sorry, piano since that's the only keyboard instrument that exists), or whatever. I'm currently focusing on keyboard because my left shoulder's having an issue that guitar really messes with at the moment. I tried Melodics because I got a free lesson or trial or something with my Akai Mini Play MK3. That was totally inaccessible, at least the iOS app was.
I've got a bunch of keyboard stuff I can work through generally, but it tends to do older songs and it's straight keyboard, i.e. piano or organ, so nothing really on modern keyboards, e.g. even simple stuff like using the pitch wheel in a performance. Also IIRC no stylistic choices.
For instance say I want to do a song that's guitar-based and mostly strumming, pick your favorite rock song as an example. You probably wouldn't just hammer out spread block chords, i.e. using both hands, to imitate the guitar. You'd need to make different choices because it's keyboard, e.g. maybe you'd use an organ to largely do sustained chords.
On the one hand, clearly I've got some ideas on what kind of choices you might make. On the other hand, examples to work through are always nice, if for no other reason than to find stuff you might not have thought of. So I'm just curious if any of these apps are usable, even from the perspective of just being able to play their songs and loop parts or whatever. I get if the notes and chords are visual that likely won't show up for us.
