Hi Steve,
I am trying to set up a translator to send fader CC value of 0-127 and output a sysex message (hex). However, the sysex message is a little tricky.
F0 43 14 3E 10 00 00 00 00 00 01 5F F7 = -40db
As you can see if the fader goes up or down by 1db, the second to last bit increments /decrements by a certain amount. This amount does not matter to me.
After it reaches ‘01 00’ or ‘01 7F’ the “01” adjacent bit increases or decreases by 1.
ie
I want to make it so that every time I increment CC fader value by 1, it inc/dec by 16 (dec) in the sysex message.
How would I make this work?
Thanks!

From the SysEX message, it looks like it is creating a 14 bit value with both MSB and LSB representing 7 bits.
The following example multiplies the input value by 16. Then we split the result off into 2 7 bit values for the SysEX message where we use tt for MSB and uu for LSB
Here are the rules.
ga=qq*16
Log "Log Input qq Output is %ga%"
// Get MSB into tt
tt=ga>>7
// Get LSB into uu
uu=ga&127
Log "Log MSB=0x%02x tt% LSB=0x%02x uu%"
And an excerpt of what the log shows
