Man oh man, you've turned a hobby into a disease
Can I suggest a couple of things:-
You may not have met the right beat box yet. For me, making beats on the MPC is a breeze and they sound 'right', whereas a whole history of purchases spanning 17 years before that I was never happy with even just a kick and snare. I dont wanna think how many bits of hardware and software I purchased because I thought it would make the difference. And accidently I discover the MPC is the one for me.
Inspiration comes from some unrelated triggers. I'm going through a whole Prog Rock revival thing (Yes is so good/bad I can't get it out of my mind), and yet I am full of electro ideas. I think the break away from any narrow music genre does the world of good. Listen to music you don't like, and then question why you don't like it. Its good for you...
Lastly, you've apparently put in a lot of work. That can't be all bad, but *you* think it has been hard work. Make it fun! Sell or buy music gear however you want. And be happy to change your mind as often as you want.
Cheers,
B
