I love that someone has to chime in and say (basically) this in every “what should I get” thread. the “new gear police…” don’t ever buy anything new! always learn every corner of everything you own first!
if someone’s not getting the results they want from a synth they have, there’s nothing wrong with seeking out a new one. maybe that synth just doesn’t work for them. or maybe they’ve exhausted all they can get out of it. there’s a ton of great gear out there. life’s too short to force a synth to work for you just because it’s there. move on. find something that inspires you.
anyway… my personal suggestion would be Digitone. you already know the Elektron workflow so you know half the machine already. I normally say it’s not great for newer users but if you’re more of a preset tweaker, it’s great. it’s a deep machine but there’s a TON of great presets, and tweaking them just a bit here and there is very clear and accessible.
