So cool, but needs improvements. – Simple Melody, Feel like a real musician and composer Review

I love this game, but I am currently requesting these stuff: 1. I saw that the conductor is coming soon (although it's taking too long to wait for it), but I want more instruments than that, like the piano, the harp, the accordion, the flute, the clarinet, the saxophone, the ocarina, and the guitar. 2. I would love to see 10 new levels for each instrument and 10 more save slots for your composed songs. 3. The violin sounds more like a viola, because it is one octave deeper. If you could make it one octave higher, I would be glad. 4. I've heard that iOS 11 is already here, so optimize this app for it.
