My goal is to export a MIDI clip into MP3 file.
I undertsand that only Audio clips or MIDI Groove Clips can be exported with the command File>Export>Audio,
so my real question is "how can I transform an exsisting MIDI file into a MIDI Groove Clip"?

I tryied to use the "Groove-Clip Looping" command, but I always got the error :
"A value of xxx for 'Beats in a Clip' is out of range. The valid range is (1-256)."

Any Hits & Tips for a poor beginner?
Thanks

Welcome to the forum.
If your MIDI clip has more than 256 beats, it can't be groove-looped.
Even MIDI groove loops can't be exported as MP3 without it being converted to audio first.

Thanks Greg, I got it now (...so easy...if you know...).
