Yes,  that's actually what I got and it makes perfect sense.

The final $10,000 dollar question is,  how do you tell a slider programmed
with that hex to change that value as you slide it.  If I enter "04 06" for
the nibbles, I'm actually HARD setting the value. That's why I thought of it
as a range when setting up the controller.  I thought it needed to know what
it's minimum and maximum value were as you tweaked it.

The Edirol Editor has a specific field to enter what/how the DATA portion of
control message is configured as.  (in the case above, we're talking the 04
06 value)

STRING : F0 01 20 01 01 16 04 06 F7


DATA MODE :
7bit
4bit/4bit
7bit/7bit (MSB/LSB)
7bit/7bit (LSB/MSB)
4bit/4bit/4bit/4bit


The last one there is the only one that allows you to have more than 127
values.  You can have up to 255.  So I believe that is the one I want to
select.

The Edirol Editor then has a Min and Max value setting for the DATA range.
So the capability is there.  But what do I enter for the string??  If I put
04 06 for the data portion, that's fixing at 100.  I can't leave "04 06"
portion blank can I?  Is the data portion of a sysex message always the
bytes before the SYSEX End byte (F7)??  Will it know that's where it's
supposed to place the data bytes.

Or do I have to tell it that's where the data portion is.......   Stuff to
ponder and figure out while I work tonight  :)   More testing of this
tomorrow morning.  Soooo close.... Sooo close....

I still find it odd that out of 2 messages I sent 5 minutes apart,  the
second one came instantly, my first one showed up 5 hours later..... ????
Yahoo... What the hell...??  :)
