you should wrap the readpointer at the end of the buffer to the  
beginning.
e.g.: play-pos+phase --> [pong~ 1 0. buflength] --> [play~ buf]

the metallic sound is due to the fact that overlap and grainsize in  
your patch are not calculated in correspondence to the actual pitch  
of the waveform you want to manipulate. to do this "right" is a  
difficult thing and you would end up somewhere in PSOLA-land, i guess.
not a complete solution against metallic artefacts, but much easier  
to do, is to add a little randomness to the playposition. [phasor~] +  
[noise~]*x --> [send~ play-pos]
volker.
