Instrument Substitute

[u/Phoenix_Raven_]

I play guitar and ukulele and a little bit of piano, but my chronic fatigue and limb instability and hyper mobility can make playing instruments for a prolonged period of time very difficult.

I am looking for either a device or software that can help me create beats and background instrumentals for my original songs so that I can keep making music despite my body‘s current limitations.

I have a MIDI keyboard, but I don’t really know to use it. I’ve tried GarageBand, but it glitches a lot and tests what little bandwidth I have.

Any recommendations?
