PX5 soundcard problem

I’m trying to record an hour long mix and keep getting audio glitches in some parts of the audio. It’s happened once using soundforge and now again using Ableton to record (i also set a big buffer). I’m on a macbook pro mid 2015 via the USB.

Any ideas what this is likely to be? Very annoying! I love the mixer appart from this issue. Thanks in advance.

Hey mate did you ever find a fix to this, having similar issues

Hi mate,

Very annoying eh?! I never really got to the bottom of this, no.
The strange thing is that when i’ve used it for a live performance (using ableton) it never has any problems and that is with multichannel audio too.

I’ve recently got a new laptop so will do a test run with that and see if i still have the same problem when recording a DJ mix.
