Great App with lots of Potential

This developer has worked very hard and has a great app idea! I use this app to get creative and come up with new sounds and practice scales. I'm still figuring out all the features of the app and am excited for more features and improvements to come.

Needs to Improve!

This scale is useful, but it can easily be improved:
1. It reverts to the default “C” when it turns off. In other words, if you set it to “A” and want it to stay there, you will be forced to change it each time.
2. The same issue occurs with one’s choice of scale. I choose the “Blues” scale, but it always reverts to the Ionian scale, which it misspells (e.g. Lonian).
3. The very same problem occurs with Tones. If you choose letter tones (e.g. “D,” it will revert to numbers when turned off. The next time you turn it on, you have to reset everything.
Please fix this app—it has great potential!
