Great Tool, but can be Buggy!

I bought this app last week. I like it a lot. Lots of chords to experiment with, and that's great, but I have one problem. When adding another chord to the song structure, it changes other chords along with it! That's a bummer. This happens almost every time. I have had to save after every chord addition. Why is it doing this? Please fix it and five stars for sure. This also has some nice sounds without having to go Midi and that's a plus too! Oh and a way to quickly undo would also be a plus. Thanks for your quick attention. Nebben

I would give it six stars if I could

I love this app. I am a musician and it gives me a portable way to quickly audition chord progressions and substitutions in a detailed but mostly intuitive UI. It pushed me to try more exotic chords that would otherwise be too complex for me with a paint or guitar. For non-musicians, I can see this as a great app to feel their way through some music without having to know how to work it out on a piano. It’s also a quick way to lay down a simple backing track to play an instrument on top of.

Best songwriting tool ever!

Seriously, this is awesome. The only thing that would make it better, and this doesn’t subtract any stars, is if there was a keyboard representation of the notes in the chords so you could more easily visualize how the non-root notes of the chords are progressing. Of course you can transfer it to a DAW for this, but it would be nice for the writing process.
