BassAsio jackaudio samplerate

hi all,
hi MrVux :)

i try to setup an audio bridge between vvvv and live
i use jack for Asio support
and BassAsio modules : Filestream + Mixer + AudioOut
everything works fine i can route multichannel audio to live
but, yes there’s a But!
the sample rate of the played sounds with Filestream (Bass) doesn’t match the Jack/Hardware one…
configuring the whole chain @ 48000 or 44100 the sound is always pitched(down)
when i try between two Ableton live instances everything is fine so i suspect
there’s something in the Bass lib config?
Julien if you’re around any tips are welcome
