I can’t believe that I left the HarPeggiator out of my examples above.  It’s virtually a multi-FX box in itself, and it’s a perfect fit for ‘series-parallel’ routings with a couple of H9s.  Depending on whether it’s configured as a slicer, pitch sequencer, filter FX, or whatever, the placement can be either 1st H9 or 2nd H9 (or both!!! ).
