Sysex Help Needed

2005-10-25 by nelsonj_sce

Hey group -
I have been doing lots of fun stuff with my K5 and I have a technical
question for the sysex gurus out there (Lesile???)

I got this Berhinger BCR2000 midi control surface and I have been
playing with it on the K5.  Very cool - and only about $125US.

First the good news:  The BCR2000 has a "learn" mode where it "learns"
simple sysex.  (More good news), the K5, with the sysex xmit turned
on, sends sysex for just about every command. The BCR 2000 has 32
knobs (but 8 can have four functions so it is like having 56 knobs) 24
push buttons (but 8 can have four functions so it is like having 40
push buttons).  As a result, you can program the BCR2000 knobs and
buttons to control just about anything on the K5. (There are problems
with parameters that have +/- ranges, and all the knobs send values
1-128, so if the K5 parameter is 1-32, only the first 1/4 of the knob
turn is used.)

Anyway, I want to assign each knob so that it adjusts each harmonic on
say S1(or at least 56 of my favorite harmonics).  Now the problem: No
matter which S1 harmonic I adjust on the K5, the K5 sends out the same
sysex.  There is also a parameter on the K5 to select which harmonic
you want to edit.  I can assign this parameter to a knob (and I can
then turn the knob to change values from 1 - 128), or I can assign
specific harmonics to a button.  (For example, I can make it so that
each time I hit button 1 on my BCR2000, harmonic X becomes active for
edit.)

So, if I want to edit harmonic X, I have two choices: 1)I can turn a
knob to select harmonic X, and then turn a different knob to adjust
the level of harmonic X, or, 2) I can hit a button and jump to
harmonic X, and then turn a knob to adjust the harmonic.

Although this is better than nothing, it is still too much of a pain
(or I only have 40 buttons and 63 harmonics) to make me happy.  I want
each knob to control its own harmonic. Period.

Now my question(s):  When I look at the K5 sysex specification, it
looks like each harmonic has its own sysex command.  Thus, it looks
like I should be able to create a sysex on my computer that will
control a specific harmonic. 
Q1: Is this correct?
Q2: For example, if I want to control the level of S1 harmonic 5, what
is the EXACT sysex command I need to send to my K5?  (I know this is a
lot to ask, but I hope someone can help)
Q3:  Just to make sure I get if, if I want to control the level of S1
harmonic 25, what is the EXACT sysex I need to send to my K5?

Anyway, any help would be appreciated.  I tried useing several editors
(including DR. Ts) but they all have the same problem - they send a
"generic" sysex that only lets you control the level of the harmonic
that is currently selected.  

I just don't know how to decode the K5 sysex spec, but if someone can
get me started, I think I can get it. 

Thanks very much in advance for any help on this.  I just think it
will be very cool to have a K5 with a bunch of knobs - each harmonic
with its own knob so you can just dail and experiment with the sounds.
