Reuse in-app content that is already purchased

Hi mDecks, I wrote you an email 2 days ago but haven't received your response yet, so I write it here to catch your support.

I am a customer of the iOS version of Mapping Tonal Harmony Pro. I love the sound of the app, but it's unfunctional without 1300+ Jazz
compositions. Unlike the competitor iReal Pro, the content isn't free here, force me to make an in-app purchase. In my opinion, $20 is expensive to put on top of the app price that is already expensive. But anyway, I purchased and felt that it's totally worth my $20.

Now, suppose that I want buy a Mac version, or if I want to have my friend trying the app via Family Sharing, can I share the 1300+ Jazz without having to re-purchase them?

Note that I have NO INTENTION to SHARE YOUR HARD WORK freely on the Internet. This is very personal to my situation. Consider that the app + content are expensive (but worthy), spending $20 for the same content is a real burden to me. Currently, I can't find any solution, I only see that you are selling it as
XML separately.

Is it possible for me to reuse the very same content I purchased for? It does not matter if the method only works for my account and not for others, because I will not share your work freely anyway.

Also, if you have no solution, please let me know too. You can find the very same email comtent. Please reply me via that email.

Thanks for your consideration.

A brilliant app. I wish I had something like this when I was in college. Just a few hours with it has changed the way I see hramonic functions. Very useful.

Fabulous composition tool

I wish I would have had this app years ago when I first started studying composition.

Starting with a key and simple diatonic chords, you can explore chord changes through related keys, borrowing chords from other keys, easily auditioning different ideas. You can also put together a chart with your chord changes, then have the app play back your progression with accompaniment (piano/bass/drums) in multiple different styles, with different variations every time. It’s like having a skilled backup band to instantly play through your changes. Once you have something you like, you can easily export to a DAW like Cubasis.

The developer is very responsive. I’ve emailed him several questions about various features and he’s been back to me with informative answers promptly.

I was a bit put off when first installing the app, and it asked me to create a user ID for an online database. I realized that all I needed to do was create a nickname and password - that was it. When I’m creating progressions, I simply mark them as ‘private’ and they are not shared with the community. But if you wanted to share them with other band members or students, you could easily do so.

I’m still exploring and learning, moving through the constellation of related chords and tools. The online database of chord changes is like a dictionary of familiar progression fragments, a very useful and inspirational resource.

Highly recommended.
