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

I have no time and all my gear is old

Haha, somehow it reminds me my own statement: "I'm too old to learn any DAW, so I'll write my own"

Yes I've been using libre softwares to make music for 10 years. Since 2 I'm also using some proprietary ones, mostly for virtual instruments.

I use Linux with Reaper, mostly with PianoTeq, Surge XT and Vital natively. I also have the commercial Windows plugins Phase Plant, Plasmonic and Kontakt. I don't use Kontakt much due to its user interface, but I guess it has its place. DecentSampler is also worth a look.

I bought Renoise Redux at some point, but it turns out that I prefer coding patterns to using tracker interfaces. Tidal Cycles is pretty cool, and there are similar. Of course I'm coding my own too. ;-)

If you are go down the same rabbit hole, take a look at: ChucK, SuperCollider, SonicPI, CSound, PureData, Faust, Overtone, BespokeSynth, Miti, and lots more!

For midi controllers, I've got a midi keyboard, launchpad, and some MPE devices.

All that said: I rarely produce music as it's just a geeky hobby for me, but I have a lot of fun. ;-)
