timing with Play

PlayTone[F_, dur_] := Play[Sin[2*Pi*F*t], {t, 0, dur}]
allows me to play a sine wave of frequency F and duration dur

PlaySeq[L_, dur_] := Do[PlayTone[L[[i]], dur], {i, Length[L]}]

should allow me to play a sequence of tones
with a given list of frequencies L
and all the same duration dur.

It does not work at least in 4.1

all tones but the last one are much shorter than dur.

any help?
