Thanks for the advice, which is very useful as always, Jim. A bit deeper into them...
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) ...
I would be using an external sequencer. Tomorrow my Oxi One should arrive to replace my BSP. Can't I just send that one's clock into Pam's?
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
I have 2 filters in there now - Squawk and the Lo-Fusion. Lo-Fusion isn't very dense but I've grown to like its raw sound. Perhaps Steve's MS-22 is similar and more in less HP, because both are based on the MS-20. We'll see.
LFO - Batumi, understood.
Matrix mixer - yes, I've been thinking about that. I saw DivKid's video on the Instruo Lion and it's an interesting non-standard approach to a matrix. Doepfer is of course a good standard. I'll need to look into matrix mixers more deeply, because there are so many different possibilities (attenuverters, ...)
consider a control module - harlequins context, tetrapad, mtm control etc - for controlling things better...
A couple of people I know send everything to a Tesseract Sweet Sixteen to keep control in one place. Harlequin - sounds interesting, but I don't really get it immediately. I need to look at it more in-depth. Tetrapad - it's been on my radar for a while now. Looks particularly good for live sets indeed.
Adding stuff is nice, but I'm running out of space. Add a tetrapad and all 3U is full. I feel like I'll need to just do it and decide what I will keep in the rack based on what actually works.
