I agree. I think it is still amazing what you are able to accomplish with a 20 year old piece of hardware.
Also, I would think it would not be that expensive to make it USB class compliant.
Right now my favorite competetor is the Nektar Pacer that has quite interesting capabilities:
I use the Nektar to control different apps on my PC. Voicemeeter Potato and OBS Studio for audio/video switching
I use Uno2 for my MIDI music setup. I also still have Uno 1.0.4 on a different FCB1010. I have a Eureka Prom that I like for IO mode only but it sits on a shelf right now. It would be nice to be able to install multiple proms and switch between them. I have no stomach for adding other hardware MODs in case I want to sell on of my FCB1010s.
It would have been nice if Nektartec had incorporated 2 expression pedals like Behringer and Roland FC300
The FC300 is nice but programming is only available with pushing footswitches. No Editor.
It also has a nice 2 line display if you don't mind looking at your feet while switching.
