MIDI to Pioneer DDJ

Hi,

I have a Pioneer DDJ-200 MIDI-Controller and it is connected to my PC with USB.

I receive the numbers of the Buttons when I press them, but how can I switch on the LEDs on the PADs ?

NoteOn(...) does not work :cry:


(Sorry for my english... :| )

if you post this is in the English forum nobody knows what code you are using. It would be better to link to the original thread if you really are looking for someone to help you.

This is the original thread: https://www.purebasic.fr/german/viewtop ... =3&t=32171

So you have the same controller as Stuhli? You didn't mention that in the thread.

Yes, its the same Controller, but i bought it :lol:

I try it here, because it´s bigger here and more traffic... i hope someone can help me.

It must be possible.... :shock:

As I have already mentioned there is also a forum from Pioneer with quite a big user base and a sub forum for DDJ: https://forums.pioneerdj.com/hc/de/comm ... 307759-DDJ
I think the best idea would be to ask them about the correct MIDI signals to make your buttons light up.

... yes, but they don´t use purebasic. :? please, if you dont have a working example, let the other answer...

to say allways the same doesn´t help me...

MIDI is MIDI. This has nothing to do with Purebasic. If you know what to send to the device the given procedures like "NoteOn" should totally work.

The main issue here is that you do not know what to send to the DDJ.

As I can read in the DDJ 200 PDF:

Illumination control:
MIDI channel 16 note xx and data 0 or 1

My interpretation:
0 or 1 is on off

Btw.:
9F 00 7F
9F 01 7F

Maybe you can only switch it on/off for all keys.

Thanks !

But, when i write

Code: Select all

NoteOn(9F,01,7F)
There is an error, because "Its not a valid Decimal number !") :cry:

Code: Select all

Procedure NoteOn(channel.b, Note.b, Velocity.b) 
  Shared HandleOut 
  Protected NoteDat.MIDIData 
  NoteDat\channel = $90 + channel 
  NoteDat\Note = Note 
  NoteDat\Velocity = Velocity 
  NoteDat\Null = #Null 
  If midiOutShortMsg_(HandleOut, PeekL(NoteDat)) = #MMSYSERR_NOERROR : Debug "Ton gestartet..." : EndIf 
EndProcedure

If you want to use hexadecimal values you have to write them accordingly:

Code: Select all

NoteOn($9F,$01,$7F)
But that's not all. The value $9f is wrong. It should be just $0f because the $90 is added within NoteOn automatically:

Code: Select all

NoteOn($0f, $01, $7f)
Or you can also use decimal values for that:

Code: Select all

NoteOn(15, 1, 127)

Thanks ! I forgot the "$" :oops:

I tried it, but no led turns on.

So, i tried the dezimal values with FOR-NEXT to see, if something happens - but there is nothing :|

Code: Select all

For a=0 To 16
 For t=0 To 128
  For x=0 To 128
   NoteOn(a, t, x)
   Debug a
   Debug t
   Debug x
   Debug "-----"
   Delay(100)
  Next
 Next
Next
I give up :cry:

If you have a program which makes them light up, you can spy out what is sended to the device.

You're loops are going out of range, they should be like :

Code: Select all

For a=0 To 15                 ;midi channel ranges from 0 to 15 !  
 For t=0 To 127              :these values are maximum 127
  For x=0 To 127
...

I think we're all assuming you have opened the device correctly in the first place? Have you? (Just checking...)

You should use EnableExplicit :!:

Then you would found:

Code: Select all

Str(InfoOut\vDriverVersion & FF)
Which is a bug.

And that

Code: Select all

Shared HandleOut
results in a bug since HandleOut is not defined.

So where comes HandleOut from ???
