In the works is a mobile version for the iphone, ipad/ipod market which is being developed by Xewton, who currently have a music app available.
The FL Studio mobile will have a step sequencer, piano roll and full song playlist just like the traditional software. You can save the files from the mobile app and load them into the desktop version when you arrive at home or are in front of a regular studio setup :)
Much to my sadness, there is no plan for an android version at this time.
Come back here, on MyLiveTube, for an exclusive interview with Jean-Marie Cannie of FL Studio when the product is officially released :)
