I think I really appreciated the depth of the engine and got some extremely cool results when I spent the time but I just kept having trouble developing intuition about whether to go to the structure page or the wavetable page to get what I wanted from a sound and found that a lot of its cool features with the pressure/velocity mod sources were really targeted at active finger drum oriented performers which I’m not so much. I typically enjoyed its sounds a lot but I have a much easier time with a DN2 or Syntakt and ultimately opted to just keep using primarily Elektrons for drums to reduce how much I have to think about workflow differences.
Really the biggest issue I had with the SY machines since most of the per-voice features are really focused at drum sounds and it was a super cool sounding synth when I got it there but building a new sound felt like too much friction for me to be able to keep using it a lot, but some of the ways different menu structures worked ended up regularly confusing me and the UI design pattern never stuck in my brain for anything but the shared features with the 12XT.
Had to let it breathe!
