Not as configurable as the SL, but you can already do a lot of slicing & filter-by-step in the HarPeggiator. I did a whole (importable) H9 Preset List based on much the same thing, if you’re interested.
But I’ll thank you for some inspiration for a Program. HarPeggiator Rhythm patterns in series with an envelope-controlled Instant Phaser …hmmm.
