I'm currently working on mixing and mastering an EP and I had several things come up I think would greatly facilitate mastering for us on the go musicians.
1) ability to mixdown to pasteboard (wav and m4a) for importation into other ios apps without either using iTunes sharing or emailing it to myself and using open as
2) mixdown to seperate tracks AND/OR option in wifi sharing to import track rails (rendering the silence at beginning) so when they are imported into other software everything LINES UP. I've muted everything track by track and mixdown with a silent backing track to preserve starting position but an option to render all at once separately and have them line up would be fairly simply (I think

3) More EQ Points
Thanks again for the only serious non-ipad multitrack option. Its a lifesaver. Please so not take any of my suggestions as complaining. I am very very happy with multitrack.
