Hello,

I am trying to play procedual midi file via unity integration on iOS，but it seems that low-level system was not wrapped by these C# code.  
So is it possible to access Low-level System via C# code? Or I must create native Obj-C code?

PS:Can I create midi-events insdead creating midi file to play sounds in .dls file?

Thanks,

artascope

Hi Artascope,

We have exposed the complete low-level API in the latest release. You can retrieve the low-level system from the Studio system object, and the API is in fmod.cs.

No you cannot fire midi events directly, you must play a midi file.
