1 channel missing when exporting as MP3

Hello everyone,

I’ve been struggling now for some hours and can’t find the answer in previous topics, so here’s my problem:

When I export my song as an MP3, there’s one channel (bass) missing.
Whatever I try, it doesn’t show up in the MP3.
I’ve been doing this with many, many Mp3’s and did this with this same song before too: the bass was there…

I’ve set my locators right, switched off the record enable, the monitor is off, even switched the plugins off and moved the bass to another channel with no bass on my MP3!
What am I doing wrong?

Can someone please help me out?
Any help is much appreciated!


Oh, btw: when I export the project as an AIFF file, the bass is there!
