I have about 20 emitters in close proximity with distance atenuation and when I walk close to them some are not playing or start on the next loop. Running on ios phone. Is this somthing to to with voices or buffer. How can it be helped?

It’s likely that your active voice limit is being exceeded. If you use live update to record a profiler session, how many active voices does it indicate are playing at the point when certain emitters fail to play audibly?
