Dave Smith Instruments SYNTHESIZERS

I don't know what happened!?!?

When I typed it up it was full of paragraph and line breaks! I am a programmer by trade, so white space IS my friend!! Maybe it is this new Yahoo Mail Beta.......

Wow, all that typing went to waste!

wow!
  
 now i know for sure I'll never do any sysex programming!  :)

      Paragraphs and line breaks are your friends ;)

>As far as I am aware, the Evolver transmits neither RPN or    NRPN's. It only transmits a few basic CC's, everything else is SYSEX.    Programming SYSEX isn't terrible. You just need a BASIC understanding of the    binary and hexidecimal notations. MIDIOX will help you see what your    Evolver is transmitting and a simple scientific calculator (like the one    provided with windows) will help translating between binary, hexidecimal, and    decimal. For example (and I'm at work at the moment, not home in front of    my manual, I am doing this from "memory"), I believe "LFO 1 Amount" is Program    Parameter #42 and it can accept values of 0 through 200. If you look in the    manual, it will tell you how to format a SYSEX message for the transmission of    a Program Parameter. It's definition is in binary, something like 1111 0000    0000 0001 0010 0000 0000 0001 0000 0001 0XXX XXXX 0000 YYYY 0000 ZZZZ    1011 0111 (XYZ are variables for different combinations 0's and 1's).
 The    program parameter list is in decimal, ie 42, and can also be found in the    manual. Your resulting SYSEX message needs to be in hexidecimal, ie F0 .........    F7. Here is a partial explaination of that binary string above. I am only    going over the important parts as most of it will be a static hard coded    value. XOk, 0XXX XXXX represents the two bytes needed to convey what    parameter you are using - in this example we are using #42. If you use the    calculator provided by Windows, in scientific mode, 42 translates to '2A' in    Hexidecimal. (or 0010 1010 in binary [notice the leading 0's, the first one    matches the template above, the second one was added because 42 in binary is    only 6 characters long and two bytes is composed of 8 characters, so the first    is "given", the second is filler]). Y & ZNow for the fun    part. If I am not mistaken 0000 YYYY represents the "least significant    byte" (LS) of the Program Parameter VALUE. 0000 ZZZZ
 represents the "most    significant byte" (MS) of the Program Parameter Value. Let's use 198 as    our Program Parameter Value. The way it is written in the sysex message is    slightly backwards. For example the binary representation of 198 is "1100    0110" LS=0110 & MS=1100.  To break that down MS=The byte containing    "anything" over 15. LS=The byte that contains 15 and under. Broken down even    further MS='1100'==192 (128 + 64) and LS='0110'==6 (4 + 2)  MS (192) + LS    (6) = 198. So to put it together: 198 = '1100    0110' }--> MS= 1100 LS=0110 }--> 0000 MS & 0000    LS }--> SYSEX LS MS == 0000 1100 0000 0110. Now to put our sysex    message together translate your binary to hexidecimal (two byte    groupings) 1111 0000 = F,00000 0001 = 0,10010 0000 = 2,00000 0001 =    0,10000 0001 = 0,10010 1010 = 2,A  <<<<< Program Parameter    for LFO Amount 1 = 420000 0110 = 0,6  <<<<< LS for    198  = 60000 1100 = 0,C  <<<<< MS for 198 = 1921111    0111 = F,7 F0 01 20 01 01 2A
 06 0C F7 Anyway, I hope this    made sense. I know it looks daunting, however one thing to keep in mind is    typically the only value you ever have to calculate is the Program Parameter,    like LFO 1 Amount. The LS and MS are typically variables, so your editor will    fill them in, you just tell it where they reside in the SYSEX string. On    my Novation Remote 25, it can only use values up to 127    ....................... ......... ......... ......... ......... ................. ......... ......... ......... ......... .............. ......... ......... ......... ......... ........... ......... .....
