FL Studio Mobile 4+

I bought the full app years ago. Why is the app asking me to buy sounds again that used to be free and sounds that I’ve already bought?

When I’m making a song with headphones on it sounds happy and normal but when i take off the headphones it turns slightly slower and the pitch is slightly lower too.
I don’t know if my headphones are doing this but please fix this if you can

This is one of my favorite iOS music apps to use. This could be so much better though. Very simple interface and is much easier to use then GarageBand or beatmaker. Though some features that are lacking are needed! Drawing in automation data is needed. Side chain compression is also needed. MIDI effects like scales and keys would be very helpful. Being able to load midi data in an individual track would be nice so I could load multiple midi into one song. Also having synths like sytrus and morphine would be nice. You only have one custom synth and would be nice to have more. All of these samples and my sample get a little boring after a while. Some updates for the audio effects would be good too. Saturation. More options on reverb. Eq 8. I would pay like 50 dollars for these things and this would instantly be the best iOS music making app on the market. Please don't change the interface though, as is very easy and efficient to use. Hopefully these will be added soon because then this is the only app I would be using!
