Love this app and think it is by far the best out there! I have a feature request which you may have accommodated through audio bus integration, but I can’t find any info on it.
It would be great to have multi track and independent mix control of individual tracks that can be saved to the song (snapshot mix control). I don’t always get the mix perfect when mixing down to stereo and it would be great to be able to adjust individual tracks and save them within the song file.
