I was talking about arduino issues related to serial to usb conversion throught the FDTI. We are making some test with other microcontrollers which have native support for midi over usb and yhe whole project is being improved. Also I give all those interesting info to norbert who is the "code and sparks" guy (I'm more the blogger and concept design but sometimes I get wrong in my tech arguments...)Originally Posted by nem0nic
No idea. Should ask Mudo, since I think he's the one who said it.
Time to talk about limitations in MIDI protocol was gone (nemonic please forget it)
About messaging and so, we are working in the same way as Hedgedog with pitch bend and 64 forward backward blablah (sorry guys my crappy keyboard hasn't all the symbols) and even considering the option of use "absolute encoder" for the future developments...

Can you tell me how this command works in detail? What does it mean if I send 64 forward 100 times a second?
Does your programming-guy know more about this?DJDiscourse.com — the new DJ community

I said "in the same way" about dealing with +-64 but not sure it is the same 100%...
so I will ask him but the source code of our project is in the web page for its examination, of course.
I'll back with more answers.

As I said before, this is probably not a great idea, especially when tools for this purpose are available for free. Can you do a capture with MIDIOX and post a snippet of that? I don't have an NS7 or I would do it myself.I've coded my own tool to analyze the data.

A relative binary offset message works like this. If the platter spins "forward" then the value of the last byte of the CC message (for example B0 01 **) will be greater than 64. And the "faster" you spin in that direction, the larger that last byte will be. This last byte value is calculated tick to tick. It works the same in reverse, but the last byte values are LESS than 64.Can you tell me how this command works in detail? What does it mean if I send 64 forward 100 times a second?
Hedgehog, you really need to do a couple things. If you do these things, a lightbulb will go off very quickly and you'll get your head around how this messaging works.
(1) Use a proper MIDI traffic sniffer
(2) Use that sniffer to simply examine how different controls send messaging. Hook up a controller and look at the output of platters and encoders. See how the messaging changes while you move the control.

@Arne:
Yes it works good but I want to go further and offer an even better option.
I'll give MidiOX a try tonight.DJDiscourse.com — the new DJ community

ali, please check this thread @vdj forums
http://www.virtualdj.com/forums/1097...J6.html?page=1
there´s a post from b1shop giving further details on every data the ns7 sends, captured with midiOX. this might save you some time

Thanks Arne.
