Hi Rick

I think you should use [vline~] to feed [tabread4~].  As long as you
get the number of samples up front with wavinfo, like you mentioned,
you can just schedule those 6 loops to play with vline~ (no need to
count and stop the loop), and you always know what sample is playing,
because it's the value of the vline~ output.

You may also want another vline~ to fade-in and fade-out.
