Depend of what you wanna do but I found myself hating using computer to make music. Since your dad and you don’t can got your own music dedicated space you could use an mpc live 2. It’s like a Swiss knife of music. It’s a sampler, sequencer, audio recorder, synthesizer, it got battery and speakers. Actually got an mpc x in my dedicated room but maybe in the future I could think about get a live 2 too
