@50Steaks IDK about FL Studio Mobile specifically, but I've done this a lot on the full FL.
My workflow often "itches" towards simpler programs like BeepBox, similar to how you're "itching" to MuseScore.
When I use FL Studio, I often take MIDIs or samples I've sketched out with BB, then importing them into FL to change instruments, mixing, etc. which FL excels at.
For me, it's converting synth -> real instruments like guitars, pianos, drums etc.
In your case it could be the other way around, real -> synths, since you're using MuseScore first.

Blend the two. MIDIs are your best friend.

Been thinking about this for a while. Only problem is the mixing. Because I’d be working between two completely different softwares I feel like it would be hard to truly unite both genres. But I still want to try.
