Minor thing : if `startPos + loopDur > buffer length` then there's silence. Example : ```supercollider b = Buffer.read(s, Platform.resourceDir+/+"sounds"+/+"a11wlk01.wav"); b.duration ( { XPlayBuf.ar(1, b, 1, 1, 4, 0.3, 1)...

Also, this version seems to always loop :) ```supercollider ( { XPlayBuf.ar(1, b, 1, 1, 0) }.play ) -> loops ``` setting `loop` to 0 does not stop the loop.
