How to get iOS to recognise/turn on Yamaha md-bt01?
I've got a Yamaha md-bt01which I use to connect my hardware synths to my iPad.
I sequence/play the hardware using KB-1, Aphelian, Fugue Machine, PolyPhase etc. All of these work great with hardware once the bluetooth connection between the iPad and the hardware is established.
But establishing that connection isn't as quick and easy as it ought to be - when I plug in the Yamaha to the hardware it automatically turns itself on but it never ever appears as a Bluetooth device in the iPads settings. If I turn off bluetooth on the iPad then turn it back on again, then even after refreshing the list of my devices/other devices its still not visible. Also no software sees it as being present.
In order to turn on the connection I rely on Volt - in Volt's Midi menu there is a bluetooth midi section and that sees the device and I can turn it on there. Once turned on I can use any other software that transmits midi.
My question is how can I enable the Yamaha md-bt01 device connection without having to use Volt? Surely it must be possible using iOS/the iOS settings app, but if I can't see it in Settings how to do that? If Volt can see it, why doesn't the settings app see it?
(Current iOS version is 13.1.2)
