^ I do have the AR but don't normally sequence it from the Cirklon b'cos its own sequencer is light years beyond the Silver generation & covers most bases for me.
Mosly I was missing individual Pattern lengths, repeats, micro timing & note masking which the AR covers.
I did find it made a huge difference to sequencing the MD probably b'cos it lacks those features.
One thing I found with the Elektrons is that as soon as you remove the internal sequencers from the equation something very special is lost. Theres a wonderful ergonomic workflow & they're so fast to program. It's almost a shame to reduce an Elektron machine to just being a sound module!
I know what you're saying about having a central point & that appeals greatly. Backing up one machine to save everything for all your machines sounds wonderful but the reality isn't quite so simple. Elektrons for example need a trig on the internal sequencer to recall a kit.
Maybe it's just my mental approach but I find it irritating that in order to gain random gate masks, inter track relationships, different pattern directions, un-impeded swing etc I have to lose p.locks & trig tracks on the MM for eg!
Guess you can't have it all or if you can I've not figured it out yet, lol
One area I'm looking to explore is where the Elektrons hold their own data but are being recorded by Cirklon. This would allow note grab which in turn could be manipulated by Aux events then sent out to the modular or whatever else! Allow you to back up the Elektron data too, well except the AR.
Bottom line with the Cirklon is that you can read & research as much as you want but until you've set it up & played with it you'll not know if it's for you.
With resale prices being as high as they are I'd just get on the waiting list, pick one up then flog it if it doesn't work out.
