Stuck on chord in tutorial

App is useless. I got to the screen that tells you to make chords and it is stuck there. Tapping OK does nothing. Reloading the app gives you the same screen. I may try deleting and reinstall, but don’t have much hope.Update: I did the reinstall and it still sticks. Also, trying to get tf8 is not possible.

So good, amazing sound but IAA does not work

This synth sounds amazing, I would have bought for just one preset, a string sound that is so so nice!

I gave it two stars in the hopes that I could get support, otherwise I would give it 5. I wanted to record that string patch using IAA in GarageBand however I couldn’t because I hadn’t bought the pro package so I purchased it and then tried recording but the sound was awful. Completely unusable and not the actual sound I intended to record. So I feel duped out of my money. I tried resetting both apps multiple times and restarted my iPad with the same poor results. Hopefully this can be fixed.

Otherwise I really really love the sound and am happy to have it but this issue needs to be fixed.
