Nothing wrong with running their modules
(though I've avoided getting a space fx, and have those "four" functions covered.).
I've used the Chaos Marbles clone often, way more than the Abacus. I'll never understand the popularity of Maths.
The 1050 mix sequencer would work great here as your output mixer or for getting a 24 note sequence from the 1027,
or just for switching signals. There's also the cable in the back to send the 1027's clock to the 1050, and a switch for it.
The behringer arp and roland clones are on discount now, I suspect that line will be discontinued soon.
I know there's a ton of them out there for the used market, but get 'em new while you can.
You could benefit from a good mult to share your hard-won generated signals.
I like the Synthrotek MST '07 Buffered Multiple @ 4HP. Best $99 you could spend here.
I think you can get lots out of what you've shown here already.
I've moved things around, mostly to help with using those little short yellow Doepfer patch cables.
