Exactly my thought 
Give ma a minute.
Added scratch function button (scratch on/off) as normally in serato.
Touch jog
Pitchband set to 50%
Scratch set to 100%
Since I don’t know how accurate your jogs are I have set round numbers for sensitivity so you can test it and tell me what should be best to inc or dec it for most perfect result we can get.

Ok sorry for the delay just give me one moment
got to setup my equipment
Hey, might want to try something else.. it doesnt scratch while deck is playing and while its paused the sensitivity isnt changed based on what i tried it just goes one really fast speed
Remember to test both of jogs, Was left one the fast and what about right jog was it normal?
When scratch mode is not activatedon the left jog, it pitches up and down a fairly large amount of bpm. but when you press scratch mode button you have to hold the button down and it pauses the song as if you were to hold down vinyl from moving whilst the platter is still moving BUT when you try to scratch it jumps to +2000 and something bpm or -2000 bpm
and forgot to say about the right jog wheel, doesnt work
Ok, first we need to make sure modifiers are working and you can check that in little modifier slots (see pic) because if modifier doesn’t work or it other words don’t change it’s value to 1 scratching cant get command to work because of modifier conditions deck A (M1=1) and deck B (M2=1).
One more thing you can try and it would be probably the best to assign it directly from controller using learn function.
Do you have an email i can send a video too? I took a quick video to show you the problems ive been having with the scratch mode… its easier just to make a video and show you
Have you uploaded it on youtube or somewhere? I have an email but if you can simply share link here. Use insert video option to upload it here or use add link if you have uploaded it already to some of sites.
Hey Stew and DJ Gmac,
First of all I want to say how grateful I am for all of your work! 
I did some searching on the internet and found an xls-file with all the midi notes of the DDJ-S1. I made a PDF file of it and wanted to share it with you guys.
Maybe it’s unnecessary, perhaps very useful
H De Peluche and thanks for your pdf. I’ve check it and actually it might get useful since G-Mac have covered one layer of midi massages and here I see another layer which is Shift+ that’s also listed (second column of CC). There is one thing tho, mixer controls seem to be missing in your pdf.
Nice search 
This 
I’ll remap current tsi for jogwheel and post it pretty soon.
Here it is, jogs + vinyl button:

It should work the same as you can do it with serato. When button is “off” pitchband should work from side of the jogwheel (nudge) and from plater (top) as well. When “on” it should scratch if notes are correct.
Once again nice work Stewe
I’ve checked the PDF file and it seems to me that mixer controls are on the last page?
There are only first column with CH5 which indicate midi channel that control is send trough and there is next column which say only CC… notes are missing.
Have you tested mapping?
I’ve tested it and it seems nothing is happening 
About the missing notes:
I think it may have to do with the fact that mixing is processing in the ddj-s1 itself and not through the software?
I believe thats one of the differences with the DDJ-T1
We are creating mapping for DDJ-S1 that’s why nothing is working for your T1…
I can inform you that mixer controls on S1 also send midi notes as I know that from first diagram.
Don’t get me wrong, I own a DDJ-S1 not a DDJ-T1
I only thought that was the reason for the missing information you were asking for…
With your beta version of the mapping I was able to control more functions of the DDJ-S1. I will try again, maybe I did something wrong when I imported the file.
Let you know!
You can control more with beta mapping because this last mapping I’ve started from scratch and it contain only jogwheels and vinyl buttons for A and B.
Does vinyl button toggle LED on each deck?
