Sound from AUv3 plugin to host on iOS

[bthj]

Managed to run a HISE plugin as an Audio Unit Extension (AUv3) in GarageBand on iOS (with sounds shipped with the plugin, but not dynamically loaded ones, as I've been able to do in other containers - will try to figure that out later) but now I'm trying to get sounds from the plugin to the AUv3 host (GB in this case):

If I assign the plugin to a track in GarageBand, then sounds can be heard when playing the keyboard in the plugin interface, but when playing the GarageBand keyboard, no sounds are heard, and when recording, no MIDI events are registered when playing the keyboard on the plugin interface (and when playing the GB keyboard, notes are recorded, but they don't trigger any sounds from the plugin).

Could this be a MIDI communications issue between the plugin and host? Do any settings come to mind that I might try to change?

@bthj err- there is no midi out form Hise is there? So any "in HISE" keyboard events wont get passed outwards....

@Lindon Thanks, but how do I get the AUv3 host - GarageBand in this case - to send messages to the plugin?

The "in HISE" keyboard test seems to confirm that the plugin is alive and can produce sounds in this context.

@bthj Im sure it is working - but as I say "MIDI out" has been a requested feature for a long time - and its still not implemented(probably because its hard to do). So your plugin wont send anything but audio out....no MIDI no other messages, audio out only.

Edit unless I'm mis-understanding what you want to do - which might be to get MIDI In to HISE - which with GB & AUv3 I have no idea

Yes, would like to use the plugin as an instrument in this host. Maybe there is something else than MIDI messaging missing? - at least it makes sound with the "in HISE" keyboard.

@bthj Have you tried a different host?

[bthj]

@d-healey Haven't yet tried another host, been stubbornly trying to get this to work with GarageBand: Kids with access to (school) iPads might be an audience for this experiment, so it would be great to have this working in a freely available AUv3 host like that. It's inspiring to know they sometimes get to play with GB Live Loops in music class (in my neighbourhood), so I thought: "Why not some (free) AUv3 plugins, too?" - but I'll try in a host like AUM and report back.
