I'm new to this.
Does anybody know how change the settings for MP3 export (sampling) in Music Creator 6?
 
Please
 

as far as i remember, when you select mp3 a new window opens and you can select stuff. Anyways, you shouldn t worry about it cause on mc6 you can only use the mp3 encoder for 1 month. (some right issues).
then you ll have to get one on your own (it s easy to find free ones on google). 

I have never used the MP3 export from inside MC.  In the export box, I would assume you simply select the MP3 option and select the kbs you wish to use....
 
This is a free feature for 30 days for new installs only. After 30 days you must buy that license separately for a fee.
 
Most folks find and use a cheap or free MP3/Wave converter and use that on the wave that we export.
 
Audacity/Lame and Wavepad are two that are widely used and are free.
