I bought an awesome DIGI-002 for $1000 back in 2004.
Av!d dropped support for the drivers in 2016. Not updating their drivers for 64-bit MacOS. (10.15+)
SO PISSED OFF -- the hardware works 100% and could continue to work another 25+ years.
Lesson learned, some companies *hate their customers*.
Invest as LITTLE as possible in hardware that RELIES on drivers, in case the company hates its customers, or goes out of business.
