I compose MIDI tracks for live performance with nearly 600 songs to my credit. I've recently decided to try using a few General MIDI files on my cell phone just for convenience. For whatever reason, when playing my files on my Android device, (and I've tried several Android devices) they all add copius amounts of reverb/echo to each track within each file. I've used the MIDI CC 91 and also 121 to try to correct the issue but to no avail. I can play these files on a Windows PC with no issues. It's apparently something related to Android devices. Does anyone have any suggestions? Thanks!
