Make a Donation

If you find free USB Midi Keyboard app and my other music apps useful, please donate. The donated fund is used for development and hardware. For example, I am looking to buy a bluetooth midi keyboard and external bluetooth speaker. After development and testing, these 2 hardwares will be supported in the app.

- Add BlueTooth Midi keyboard connection
- Fix Yamaha pitch in app page

  1. Nu stiu sa fac asta fac sa mini

  2. I want to install this on my new phone but I cannot find you now on Playstore. What an I do? Your app works great using USB OTG, no lag and awesome sound. I use MIDI key board and USB OTG so your app has become a very portable performance-grade jamming rig. More power! Just wishing to find you on Playstore for my new phone! Please reply!
