I have posted in other threads that the delay in development is due to Apple and Windows updating the USB drivers in their operating systems. I use OB for my AR and AK and experienced a sharp decrease in bandwidth when I updated to High Sierra. I now have to run each through a separate USB port, even using Overhub.
Obviously, Elektron can’t blame it on another company, but I can and quietly do. I haven’t seen any real aggregate demand for higher USB transfer rate, even from the audio world (typically picky customers), but I have seen plenty of complaints about lack of compatibility due to “updated” versions of software. (I would actually appreciate a real argument for the benefits from someone who is more acquainted with the technology.)
Yet, the “next version” is always pushed out in order to sell more gadgets (and higher priced cables) at the expense of users and other (smaller) companies. The industrial revolution succeeded largely in part to STANDARDIZATION which the digital world seems so willing to ignore.
Addendum: Elektron makes hardware the lasts decades. They are a functional physical asset that will appreciate over time. My computer from 2001 is useless, and the OS is about the same, but MD is still in demand. That is just the nature of the high-end drum machine market and the computer market. The interface between those markets is naturally chaotic, and unfortunately the drum machines lose out to the numbers.
