The only other music or audio app I use with any regularity is Reaper on Windows. I tend to do more performance-oriented stuff, and I try to keep everything outside the computer as much as practical. I don't use any software synths. I like the constraints and UX of dialing patches into my one keyboard/drum machine. I record some, but mainly I like to play in real time and not fiddle with VSTs and plugins.
My only Apple product is also an iPad, and I mostly use it to make music with Auxy Studio:)
Do you use any fun apps on Android? Currently, my favorite apps are Digitron and Nanoloop. (No affiliation, but Digitron's upgrade was gifted to me.)
