I bought this app last week. I like it a lot. Lots of chords to experiment with, and thats great, but I have one problem. When adding another chord to the song structure, it changes other chords along with it! Thats 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 thats a plus too! Oh and a way to quickly undo would also be a plus. Thanks for your quick attention. Nebben
