advice:
use Pam's as the master clock in the rack - if you want to record, use an audio track with a kick on it every 16th note and run that through the es9 into Pams (set Pams to receive 4ppqn) ...
2nd filter/effects module would probably be a good idea - change things up quickly and easily... possibly more mixing... for sub mixes of vco outputs - before hitting filter/effects
possibly replace the doepfer lfo with something like batumi (4 channels) - consider a matrix mixer with big knobs (doepfer) for combining modulation sources to get more interesting modulation
consider a control module - harlequins context, tetrapad, mtm control etc - for controlling things better...

Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
