I worked at Moog back in the days of dinosaurs and analog and steam power, and this situation looks familiar to me. Sometimes an engineer (who is not a musician) will come up a concept that he thinks is just brilliant. If he is a person of great charisma and likability (not common in engineers, but it does exist), he may be able to convince some marketing people that this concept just HAS to be included in the project at hand. And sometimes it happens at the expense of other, more desirable, instrument functions. I think someone fell in love with this idea - that you can reasonably approximate a volume pedal with a sustain pedal. "No need for a second pedal!" In itself, it's a good idea. But not if you have to give away any possible use of CC pedals. This is a facepalm moment on an otherwise really first-rate instrument. I have a couple of MIDI CC pedals, and they add a lot to the authenticity of the PX organ sounds - I can't use 'em without it. In my opinion, the whole volume pedal issue is a conceptual oversight that I doubt will ever be corrected.
