[LCtalk] fading with midi

[mailing]

I'm doing some experiments to control the lanbox by midi only.

I have some RGB ledfixtures and I'm triggering some color changes.
I've made the following patch.

 on note on :
   midinote C#0 velocity :  127  - R color
   midinote D0 velocity :    34  - G color
   midinote D#10 velocity : 127  - B color

 on note off :
   midinote C#0 velocity :   9  - R color
   midinote D0 velocity :    0  - G color
   midinote D#10 velocity : 38  - B color

So there aren't any note off send to the lanbox, only note on's with
velocity changes.  This works perfect.

I also tried to use some fading. That also works, I can easily change
all the fading settings with midi.

The problem that I see a fast "green" flash ( so G at at a maximum ) if
the fading curve ( generated by the lanbox ) ends.  Very strange because
that value is never set at a maximum.

I've found a solution for this problem, to program a little green color
( CC value 2 ) in the "note off" part.

However I'm curious what's exactly happening and why I get that little
flash in this setup.
