I am also using Ableton but have a Beatstep Pro...I've been using the BSP as my primary clock source in my setup (which also includes a Hydrasynth desktop and my Rackbrute 6U. Also more recently integrated iSpark (drum machine) on my iPad with it as well (so I can have drums if I ever go remote...Ableton is on a desktop for me currently)
If I'm not mistaken, that DFAM has its own enclosure? It takes up a HUGE chunk of real estate in your setup. There is a calculation that can be done to demonstrate the extra $ it costs to include that in your setup...maybe you're considering removing it when you fill up more HP on your setup?
Curious as to why you're looking for more sequencing power when you are using Ableton Live and KSP...are you using CV Tools in Ableton? what are you looking to do with adding a sequencer in rack (more just curious than anything since I'm newer to modular).
