I can relate to this for sure. What’s helped me is not putting so much pressure on myself to create top notch works in 1 or 2 sessions. Focus on having fun with sound design and composing, the rest seems to fall into place afterwards. Also being realistic about output and knowing that not everything I create is going to be good. Sometimes I’ll have a pattern and just think, “this sounds like crap!” But I try not to get frustrated.
As for your stuff being loop-based, most music is loop-based or at least has some repeating elements involved. If you’re having trouble in that department, just try and add little variations / transitions / mutes / risers / etc… To your composition. This breaks up the monotony. It can be easy to get stuck in loop land with 64 step sequencers.
And to answer the original question as when I make music, whenever I have time and energy. I was just fudging around with some patterns a minute ago while my girls were playing. Only for like 10 minutes, but that 10 minutes is still worth it. Late night is usually my time to dig in, from 10pm - 2am, as long as no work the next day. Also sometimes if I wake up early enough, I can get an hour from 7am - 8am before work. Just gotta find time and force myself to get in the studio!
Don’t be so hard on yourself! Keep creating.
