I think the fact that there is no explanation of the different velocity curve settings in the user manual, coupled with the fact that there is no audible difference when a different curve is selected, leads me to conclude that the velocity curves are a complete red herring and serve no purpose at all - same goes for the Rev2 synth too.
DSI/Sequentials silence on what the curves do is deafening, which only further solidifies my belief that there is no difference between any of them and they serve no purpose.
Still a great synth but It’s a shame that such a basic function hasn’t been implemented.
3ven my 1996 Roland XP synth has properly explained velocity option.
