One of the Elektron Overbridge boxes would be the ultimate compliment to your existing workflow.
I’ve already evangelized the Digitakt once tonight, so I’ll spare you about how the Digitakt is the greatest most fulling and rewarding machine I’ve ever encountered, and instead I’ll evangelize Overbridge.
Overbridge is all encompassing- you design a pattern and you jam while you’re running Overbridge and the plugin will save all of your tweaks for you to edit after your performance. It’s so convenient to use the onboard fx while splitting your individual tracks- or if you have fx you prefer to use, super easy to do that. Also you can combine your groove of jams with the virtual environment of VCV Rack/Reaktor/MaxForLive
It really is all the fun of composing on hardware with the precision of having a software workflow.
That being said- Octatrack will not harmoniously enter into your Ableton workflow as many of its functions need to be done locally.
Model:Samples might be good on the go- when they come out with their battery, but that’s more of a portable workstation than a complementary one.
