Request for new feature

[Fire ant]

Hi 

     Your app will be really helpful for me .Unfortunately the new update does not support my keyboard.The app can't connect to it .I have a very old yamaha PSRE403 arranger keyboard and I don't have a pc .This keyboard has USB midi but only supports some android apps . I think it is not class compliant.

   However it do work with old versions of midi arranger.From what I know the culprit is the new Midi API .I have a suggestion. Give an option to change between multiple midi api within the app.I have seen this in other apps like rock relay synth FM.If you dont understand what I am saying check it out from play store.This feature might also help other to switch to suitable midi api for their devices.btw your app is a game changer for me .It has potential to replace those huge arranger workstations.😁

    Please regard this suggestion if you are Interested.

                     Thank you.

Hello
Greetings to You all. 

I encountered similar problem - old PSR-E413 also is not recognised by the app, probably because it's not MIDI class compliant. Basically, Android doesn't seem to recognize it as a MIDI device.
(OTOH, iPad Air 3 works with the PSR without any problems, probably wider and better driver implementation in OS)
I have other keyboards and MIDI USB interfaces and they're working on Android, but I wanted to "replace" the style engine in PSR by this app, and so far no luck.
https://github.com/kshoji/USB-MIDI-Driver suggests that this might be some non-standard USB MIDI protocol, but it should be possible to implement using some specific vendor codes (sample project does transmit data to my PSR)

Could You please look into it?
Thank You and best regards
