since the question was synth and not sampler… and I am going to assume we are not recording into a DAW so it’s got to be multi channeled/voiced… So my list
Rytm(though really works with samples layers… This basically is why the octo is out)
Syntakt
LXR-02(though I feel like the techno is going to start to sound the same)
Roland Groove boxes - TR8S(though again really only work with samples)
A4
Digitone
309 Raveolution
pretty much any good drum machine that allows sound design(and again sample layer really helps)
I am sure I am forgetting a tone of stuff too… like the electribe ER-1 for example
