Yes, this application has been around for about 5 years. So far, it's more of a gimmick than a serious DAW application. The beginning is already there, but the overall implementation has more or less quirks that lessen the fun here, and we need to update to a new version with the name FL Studio Mobile Mod APK.
In addition to a new, more colorful (brighter) track view and foldable controls, you also get a step equalizer, drum pad, and piano roll editor for MIDI "notes". The available instruments are synthesizers, samplers, drum kits and loops, all of which can be controlled via the touchscreen, folding keyboard, and external MIDI controller. The on-screen layout is also new: it is no longer swapped through functions and tools in tabs like in an Internet browser, but from now on in split screens.
However, the most ingenious feature is the plug-in version: You can download the desktop version of FL Studio Mobile 3 as a plug-in, continue to work on the project comfortably and later then edit it on the tablet after syncing. Excellent! IMHO is an important step in DAW work, from which all manufacturers can learn a part.
I'm also linking the video shown below, unfortunately it's mouse operated and makes no sense teasing the tablet version. But you quickly see how unlucky and intrusive the new color is. The Image Line will quickly implement the enhancements.
