MIDI + rslider Q's

Hello -

I'm putting together a patch that involves scaling MIDI controller values to control the two points in an rslider, and a couple of issues have come up.

When using its assigned fader on my controller (#72), the rslider won't output the high value unless the fader controlling the low value (#73) is moved simultaneously. It displays its position within the rslider, but nothing is displayed in the flonum connected to its output. If I use the mouse, it works just fine.

Then, assuming I can get this worked out, I'd like to use the third fader (#74) to scroll from side to side through the rslider, while maintaining the range set by #72 and #73 -- the same function as using the command key and the mouse within the rslider.

Here's the chunk that I'm talking about:

I very much appreciate any and all feedback!
