K5synth

Me again - 
Well I spent some time with my K5/MidiOX/and my BCR2000 and I got 
very cool results.  Recall the Behringer BCR2000 is a midi control 
surface with 32 knobs and 30ish buttons.  The best thing about it is 
the BCR2000 can "learn" sysex.  To make a long story short, I was 
able to figure out how the K5 sysex works for changing harmonic 
levels (it is a two step process), then I wrote a sysex script in 
MidiOX that combined the two different K5 sysex instructions, then I 
sent this compound sysex to my BCR2000.

The result:  It worked!  I now have a real-time, dedicated, one-knob 
controls the level of one-harmonic setup! In other words, a K5 with a 
lot of knobs!!!  That is, if I want to adjust harmonic 8 (for S1) in 
real-time, I just turn knob 8 on my BCR2000 and vola - I can directly 
dial in any level from 0 - 99.  Same goes for any other harmonic 
(with a few work a rounds for harmonics 56-63 because I ran out of 
knobs), just turn a knob and -boom- the harmonic level changes.

Right now things only work for S1 (I have to write a script for each 
harmonic, one at a time, and then teach my BCR2000...a few hours to 
get all 63 harmonics), but I only have to make minor changes to each 
harmonic sysex script and I can repeat the same process for S2 
(again, several more hours...).  The BCR has 32 programs, so one 
program will control S1, and a second program will control S2. I can 
also do things like control filter freq/slope/amount and other key K5 
functions by using a third program.  (Envelopes don't work that well 
because they have a 0-32 range, where the BCR sends out 0-128 values, 
so only about 1/4 of the knob range does anything.) 
  
I hope to post a BCR2000 file here (if I get around to it with all my 
other projects...)once I get S1/S2 working.  That way, if anyone else 
has a BCR2000 they can just load up my file into their BCR2000 
(instead of spending hours and hours doing what I have done...) and 
start tweaking their K5.
