Thanks, I'm wasn't sure if it sounds quite right (I don't have windows + VDJ
around to compare scratching mode with).
I realize the code is a bit of a mess (part of that is historical - i.e

Not exactly... When midi script was first introduced, the "channel" in the
call back method sig "function (channel, control, value, status) {" was
"[Channel1]" or "[Channel2]" which made it very easy to figure out which
deck to apply the control behaviour against (i.e. you got "[Channel1]"
jog_wheel -> you were applying a change against "[Channel1]" "scratch").
Somewhere along the way channel was changed to become the midi channel
number from the control changed... meaning there is no longer any way to
tell which "[ChannelN]" the binding is for...
That resulted in the following method to look up the "[ChannelN]" value
based on the physical position of the control with this function... IMO
its a bit ugly
HerculesMk2.getChannel = function (control){
// get the "group" that used to be provided in channel, this is not reusable
across devices
// and also breaks remapping of these functions to other buttons.
controlToChannel = {
/*
0x2F:"[Channel1]",
0x30:"[Channel2]",
0x0C:"[Channel1]", // Cue
0x24:"[Channel2]",
0x0B:"[Channel1]", // Play
0x23:"[Channel2]",
0x0D:"[Channel1]", // Stop
0x25:"[Channel2]",
0x12:"[Channel1]", // Load Deck
0x16:"[Channel2]",
0x2F:"[Channel1]", // Jog Wheels
0x30:"[Channel2]"
*/
0x36:"[Channel1]", // Mk2 Jog Wheels
0x37:"[Channel2]"
}
return controlToChannel[control];
}

I believe the LEDs on the Hercs accept 0x00=off and 0x7F=on values only...
The HerculesMk2.leds in the code I sent is a copy of the RMX leds (remember
I just copied the script and renamed RMX->Mk2), you'll have to replace the
values with the LED values in the back of the Mk2 manual for it to behave
correctly.

Back of the Mk2 manual documents all midi input and output codes on the
Hercs. I'm thankful Hercules actually did this, because makes it very
straight forward to figure out mappings for.

I think there is a way to do it via sending some midi signal to it, but I
don't know any details of how it works.
