It’s not so much the delay/reverb send effects that I’m talking about, those are good but not that different to the TR-8 (the tape echo is great though).
What I’m talking about is the per-track INST FX setting. Every instrument channel gets one and they can all be different. There’s filters (LPF, HPF, and LPF/HPF which transitions from one to the other like a DJ filter), high/low EQ boosts, Isolator (which is like a three-band parametric EQ), Transient (which emphasises attack/release), compressor, drive, combined comp & drive, and a bitcrush.
It’s these INST FX that allow you to punch sounds up way beyond the standard TR-8/08/09. And being able to freely assign any sound to any track (just like a Machinedrum ). That means you can layer bass drums, etc etc.
Aside from all the out-there stuff you can do, the basic kit building is very strong and very flexible.
