Just curious, but what would you ever leave permanently UP on the modulation wheel?
If you are thinking filter cutoff or something like that, you see, Roland use the SLIDERS for voice programming, no need for the mod wheel.
The lever basically just does vibrato (and a trumpet 'growl' on the E80), and other than Farfisa type organs, what sound needs constant vibrato? (and if it does, you can program the voice to have it permanently, or with a delay)
Yes, I spent years on Minimoog's, etc., and still have my DX7, and a few other things that have the two wheel system, and it's a great system, but I have had no problem over the years with the Roland system, either. Aftertouch and the sliders have always allowed me to achieve the same end result...
What I REALLY want is a pitch strip like Korg and Kurzweil... Hammer on/offs, trills, scoops, doits,, playing lines without re-triggering the voice (a BIT like SA), all of these are a snap on the pitch strip....
