Using Studio One 4, I have a number of vsti's, all of which export perfectly. Not Modo Bass. I have looked at the file and there is no mute, cc, anything at all that would prohibit it from exporting with the track. I tried transforming it to audio - I get a complete track with no bass. I can hear the vsti playing from start to finish. I took the midi and made a track in Sonar - same thing.
I also made a brand new S1 4 song, same thing - nothing. Can anyone shed some light why this is? Also curious why Modo only operates at 48K. Yes, I did change my song to 48K - even though modo plays in the song at 44.1. Weird. Much appreciated!
