Just so you know for future scammy bit.ly links. You can put a "+" sign at the end of the URL to see where the link leads, as well as some stats for the link, like this: https://bitly.com/2JNRCAe+
It's quite definitely scammy though, so be sure to report it to bit.ly's support: https://support.bitly.com/hc/en-us/articles/231247908-I-ve-found-a-bitlink-that-directs-to-spam-what-should-I-do-
Bit.ly is usually rather responsive with scam links.
At this point, I wish Martin would just dash the entire all-in-one ego destroyer of a monolith machine and just focus on smaller, separate instruments that each provide only one aspect to his compositions. He's shown to be adept at this with his lovely Modulin.
If branding and viewer excitement is a concern, these new instruments could be simple enough for the audience to actually follow along, slowly turning the viewership from one of passive second-guessing to one of active making and performing. It's much easier to hack together a working Modulin (https://www.hackster.io/davy_j/digital-synth-modulin-wintergatan-inspired-ab2b83) than it is to even do a price analysis on how much a MMX would cost to make.
Not only does he get to spread the final musical project over more performers, each instrument will have clearer constraints, smaller scopes, and (much, much) faster turnaround time while keeping with his lovely DIY aesthetic.
Wintergatan Live is more than one person and I bet all his usual collaborators would be interested in taking a custom tool in hand to make his next body of musical work a unique reality on stage.
I purchased one based on how useful it looked in Martin's videos and it has lived up to my expectations, despite being expensive. Wera makes very nice tools. https://smile.amazon.com/gp/product/B00IMF1CDO/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
I have such a [suggestion] and other one year ago, you can watch there : https://photos.google.com/share/AF1QipM0pp0aTF2LpmzLALvZ81jJzGF-v-Z8qV5sB9Mn437d_keGZxmEg4aYJM-rUSKoAA?key=UmlmaHdCVVVIOVdYMjBtNFFzTjR1RUdQZ1FBX0h3
FYI, I'm working on a self-contained digital modulin with 5 "strings", built-in speakers and battery, and an output jack for connecting to other equipment. If you think it's cool I'd love some likes on Hackster (part of a contest that ends tonight).

I'll be updating it later with a more appropriate (and cheaper) microcontroller that will increase its capabilities.
Depends how many pieces you want in the set, you should get a smaller one for half as much like this one:
