I’m in exactly the same boat as you. Bored of sitting at my computer staring at an arrangement on the screen.
For me taking the visual aspect out of it is the main pull. I think it will force me to use my ears more. I also think it will be more intuitive and fun to create music on an MD instead of using my mouse for 90% of the work.
I chose the MD SPS-1 UW+ MKII as my first, which I have only just ordered. I plan to add a Monomachine when I have the money.
The main reason I chose an MD is because drums and percussion make about 80% of the style of music I produce, and in some cases it’s nothing but drums. Plus if I can’t get the sound I want out of the MD I can just record my soft synths and upload the samples to the UW.
