Well even the Pioneer SP-16 (and all it’s lack) has a ducker effect. Keyed to the kick drum is pretty handy for making baselines sit in the mix without having to set up a side chain compressor path. Also gets a pumping sound that that lame compressor on the DT can’t touch. Can sort of get it going mildly on the DT, but push it too much and everything distorts.

But I don’t know why they did not implement the same compressor setup as on the DT. maybe it’s a HW limitation?
