1. When I did eventually manage to connect my instrument via Bluetooth ( needs the gps on for some reason but nowhere says that) I have all these great sounds that are unplayable on an android phone because of the delay between phone and instrument.
2. And since Bluetooth is useless for actually playing the extra sounds, except to test them (and they're pretty good, too), Android users find themselves in the frustrating position of hearing the sounds, wanting to play them, but being unable to do so in a useful way, due to lag.
3. Generally an unlikeable app for an unlikeable instrument (an opinion formed over a year of using one)On my Samsung, for USB Midi you need to set the Android USB mode to midi and use an OTG cable or USB hub.
4. All in all, I am pretty happy with the app.After finally realising that the Aerophone GO wouldn't connect via Bluetooth as my phone's GPS wasn't on (???), I managed to get it to connect.
5. But the serious problem that has been noted by others is that the latency when playing the sounds in the app is bad enough that you need to use the USB connection.
6. enable developer settings on phone by tapping on the build number a few times, then in developer menu change the usb mode to always MTP, and disable usb debugging if its enabled.There is nothing that works on this app.
7. my blackberry keyone never finds the device with usb or bluetooth through the app, i can pair it outside the app and use the aerophone as speaker but inside it never appears in the midi device list.
8. The phone just doesn't recognize the connection, so it's Bluetooth or nothing.
9. For all the effort though, you might as well do it on a PC/Mac with a high quality synth.I wish to know how may I make the phone to not go to sleep mode or screen fading while using this app.
10. Complete waste of time and makes Roland look like clownsBluetooth very unreliable, latency on app sounds just make it completely unusable for anything other than a page of legato minims.
11. The cable connection doesn't even work, and you can edit anything useful in the aerophone.
