### 4/5 — Great app for working with Music and Visuals

I love this app and just subscribed for the full version, however I’m got some problems get Midi mapping working with a Bluetooth MIDI keyboard controller.  Also it would be nice to be able to save over presets.  Is there a full manual available. Thanks for  great app!

**Developer response:** UPDATE: I implemented Bluetooth MIDI Connection sheet inside AV Synth. Check it out in the MIDI section, you should be able to connect and use MIDI Devices via Bluetooth now. This went live with version 1.12.0. Let me know if it serves your purpose!

Hey there, thanks a lot for the feedback! I would be really interested in further adjusting the app to your needs. If you let me know more in detail what is not working and what improvements you're looking for, I would love to help improving AV Synth here. Just let me know via email: info@mkgames.org and I'm sure we can make the Bluetooth Midi work. Also let me know what exactly you mean with the Presets as there is already an option to save, load and export Visual Presets. You're talking about an option to save / load MIDI mapping? 
- best Marvin
