Hi nickrose!

These are a part of sysex send by DSP4000 when a "userobject" parameter increase from 0 to 40. I've just took numbers which are changing, the "four hexadecimal numbers", other numbers are allways the same due to the sysex format. In the list I've send, the first number before comma, is the decimal value that appears on the display of DSP4000, then the four hex number that are changing in the sysex sentence. Example: for the decimal number 2, DSP send (240 28 112 1 2 0 2 0 0 0 0 0 8 0 0 1 12 0 0 0 1 0 0 0 0 0 0 0 3 0 0 0 0 0 0 0 4 4 0 0 0 0 0 0 0 247), for 3 ( 240 28 112 1 2 0 2 0 0 0 0 0 8 0 0 1 12 0 0 0 1 0 0 0 0 0 0 0 3 0 0 0 0 0 0 0 4 4 0 4 0 0 0 0 0 247;…for 6 ( 240 28 112 1 2 0 2 0 0 0 0 0 8 0 0 1 12 0 0 0 1 0 0 0 0 0 0 0 3 0 0 0 0 0 0 0 4 4 0 12 0 0 0 0 0 247; for 7 ( 240 28 112 1 2 0 2 0 0 0 0 0 8 0 0 1 12 0 0 0 1 0 0 0 0 0 0 0 3 0 0 0 0 0 0 0 4 4 0 14 0 0 0 0 0 247; for 64 ( 240 28 112 1 2 0 2 0 0 0 0 0 8 0 0 1 12 0 0 0 1 0 0 0 0 0 0 0 3 0 0 0 0 0 0 0 4 4 2 8 0 0 0 0 0 247;  and so on….

I would like to control DSP4000's parameters  by sysex, to use it "live". I've started to create a patch with Max/MSP, like a remote on my mac. My problem is that I can't understand how decimal numbers are encoded to Hex numbers, it seems to be unusual, isn't it?

thanks!

best regards.
