Generally good piano roll implementation, controls. It'd be nice to have a master fader and possibly a compressor amongst the effects implmemented.
I'd also love a swing parameter.
Something I've noticed is that knobs with a touch screen can be rough since your digit is covering the visual feedback. Maybe a single vertical line indicator next to the knob could mean you would know where you are and how far you can go when tweaking one?
There's also the issue, at least in the U.S., where homeschooling is really kind of a code word for "religious, non-secular" schooling. Anything from evolution to certain history is skimped over and treated in a "just learn this for the test, but don't believe it" kind of fashion, which is extremely unfair and unfortunate for the child in those situations.
The biggest issue I really have with homeschooling, tied into the previous paragraph, is that you end up getting absurdly unqualified people teaching their kids (and sometimes other people kids!) subjects they have absolutely no clue about! For a group of people that tends to be extremely vocal about teaching "organically" and not by the book I've never seen any other population so reliant on textbooks when it comes to a variety of subjects. The kids basically lose out on what would be a "pseudo-professional" in what ever subject they're studying, who would able to guide them through certain areas of the subject the text book may not gracefully cover or maybe even not cover at all! Instead you get a stay at home mom, dad, or some kind of combination thereof that didn't bother to study the subject they're trying to teach _and_ went to a public school themselves on top of it all.
All these posts seem to be far fetched rationalizations when it comes to homeschooling. There's nothing stopping you from teaching your kids things you want them to learn, beyond what schooling will give them. But it's been plainly obvious to me personally that homeschooling doesn't really give you anything extra, or circumvent problems with the education system, it just takes away from what you would have gotten while claiming it's doing the exact opposite.
Most everyone, given enough time away from homogenizing environments like public schools, becomes increasingly differentiated from the norm. They find their tribe and grow into that niche instead. Then, when tribe members cross paths outside their tribe, people sense something "off" about the other.
