Hello,  
I am switching a channel from 3D to 2D by first calling \_channel.setMode(MODE.\_3D | MODE.\_3D\_INVERSETAPEREDROLLOFF),  
and then \_channel.setMode(MODE.\_2D).

When I get and print out the channel’s mode, it is \_2D, \_3D\_INVERSETAPEREDROLLOFF.

I would expect it to simply be \_2D. But instead, it still has the 3D rolloff value. Why is this?

Would appreciate any support, thanks.

I am unable to reproduce that behavior myself, what version of FMOD are you using?

Are you also checking the result from the `setMode` function call?
