I think I could definitely have good times with: Laptop/DAW, 2 Bastl Micro Grannies, an RME Babyface Pro, and assorted cabling to connect it all (might need/want a MIDI device to hand the lack of thru on the Grannies).
My thinking on this is: if Iām somewhere new I would have a lot of fun sampling the local environment and building up tracks based on that. Having 2 Grannies means Iād always have one on me in the field and also would let me set up one to be controlled via laptop/midi while I play one live during sketching. Then lay it all down on the DAW.
Now that I talk about it here, I kind of just want to make some tracks like this.

In reality, I often travel with a 19" box of modular + 1 row of tile (Pulp Logic frame and tiles in a road ready lighting controller rack), a Mackie VZ802 (the routing capabilities on this are the secret weapon), and the RME Babyface (comes with itās own hardshell so I can throw it in the backpack). Thatās my normal on-the-road rig. But itās bigger and heavier than what I list above and also requires two bags: one for RME/laptop/mackie and then the separate modular. Thereās a reasonable chance I could live just fine with the Bastl Dude and save space/weight. I like having the options for lots of inputs though in case I am collaborating with someone.
