sourceSamplePosition in SamplerVoice

Would like some input in getting the sourceSamplePosition value for my class. Failing this, is there any other method I may pursue to get the current playing position of a samplersound object? I'm trying to make an indicator that shows the current position of sample playback similar to what's available with transport setFollowsTransport.

 

Thanks in advance.

For something like that you'd probably want a customised voice class, as SamplerVoice is only very basic and isn't designed to support that kind of observer in a thread-safe way.
