groove~ audio problem in max 7 ?

Hi,

I think there might be a bug in Max 7:

If i load a 6 minute sine test signal (48k,. wav) and play it back with groove~ (Max 7.3.3) I get strong artefacts.

If I do the same with sfplay~or play~ — no problems.

If Ido the same with groove~ in max 6.1 — no problems.

Can anyone reproduce this problem ?

Or is the audio somehow preprocessed like e.g. the warping in Ableton Live ?

Thanks

No specific patch, just used the help-patcher to avoid any "patch-related" problems.

The sine wave file was -20 dB, 48kHz.

Bizarrely the problem was not audible anymore when I turn on (!) the timestretching.

Maybe a stupid remark, but what sample rate setting are you using for Max (Audio Status window)? Could be related to something specific with groove~ and a discrepancy in sample rates between the sound file and Max itself. Just a hunch, though..
