Dynamic composition of a SysEx message with variable content and length

Scripting with Gig Performer

Can you paste your Script?
Did you give the midi out plugin the gpscript handle KeyLab_mkII_49?

i had a typo now it seems correct it is compiling but “says”
Plugin ‘KeyLab_mkII_49’ not found in rackspace ‘emu/jup/modular’…it is not recognising it
do i ha to use the whole “caption” of keylabs midi out? that would be:
MIDI Out (KeyLab mkII 49)

var
KeyLab_mkII_49 : MidiOutBlock;
SysEx : SysexManager;
KeyLab_mkII_49_LCD_PRE : String;
KeyLab_mkII_49_LCD_SEP : String;
KeyLab_mkII_49_LCD_END : String;
ASCII_STRING : String;
ASCII_HEX_STRING : String array;

Initialization
ASCII_STRING = " !"#$%&’()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[Y]^_`abcdefghijklmnopqrstuvwxyz{|}><";

KeyLab_mkII_49_LCD_PRE = "# F0 00 20 6B 7F 42 04 00 60 01 ";
KeyLab_mkII_49_LCD_SEP = " 00 02 “;
KeyLab_mkII_49_LCD_END = " 00 F7”;
End

Function StringToHexString(str : String) Returns String
var i : Integer
result = “”;

For i=0; i<Length(str) ; i=i+1 Do
result = result + ASCII_HEX_STRING[IndexOfSubstring(ASCII_STRING, CopySubstring(str,i,1), True)];
End
End

Function KeyLab_mkII_49_LCD(line0 : String, line1 : String)
If Length(line0) > 16
Then
line0 = CopySubstring(line0, 0, 16);
End
line0 = StringToHexString(line0);

If Length(line1) > 16
Then
    line1 = CopySubstring(line1, 0, 16);
End
line1 = StringToHexString(line1);


SM_CreateSysexFromString(SysEx, KeyLab_mkII_49_LCD_PRE + line0 + KeyLab_mkII_49_LCD_SEP + line1 + KeyLab_mkII_49_LCD_END); 
SM_SendMidiOut(SysEx, KeyLab_mkII_49);

End

On Activate
var s : String;
s = “Rackspace:”;
KeyLab_mkII_49_LCD(s, GetRackspaceName());
End

You have to give the gpscript handle.
Available via the popup menu you get when your right click with the mouse on the midi out plugin.

hmm still does not display anything-gotta dig deeper

66

On activate is executed when you switch to that rackspace,
Did you do that?

67

here comes the anfänger : where do i do that?

68

Just create an additional rackspace and then navigate back to your rackspace

69

i do have two, both with the arturia midi out and the script enabled

70

Now when you switch between them, what happens?

71

change of preset works like before,but the dispaly (in whatever mode) does not “see It”
i am supposed to be in user mode if ia m correct

72

ok i have to be in analog lab mode/preset it does show the second one but not the first one
wich has exactly the same script

replaced the first with a copy of the second one now it works!

Strange you had to copy…
Maybe the script was not compiled.

74

maybe, egal it works,now i have to find out how prevent the keyboard from changing display change everytime i push a button on it, therefore on a gig, the keyboarder sees the rack he is on-thats all the info he needs live…
he wants to use 8 of the pads (top left there are 16) to change presets (8 is far enough for him) but everytime i push one, the display shows the value ,there is no need for it,i jist want a change if the rack gets changed on the display

75

Does he have an iPad?
with Catalina you could use an IPad like an external monitor or you use duet - a special software.
I think this would be much easier than program the Arturia display.

Or use TouchOSC on an iPhone or Android.
It would be trivial to show the rackspace name on a mobile device.

76

that is probably the way to go, he has a ipad - noten - thanks a lot anyway

77

Is it the standard display even if you don’t connect it to the computer or is it a feedback from the computer ? Does it still happen if you open the Arturia ports with GP again ?

There is also the solution to display your custom message again using a timer…

There is also the solution to display your custom message again using a timer…

this is what i need - basically when i recall a rack / variation on the computer it displays correctly the rackname on the keylab
now of course i send from the keylab (pads set to send programm change) to change variations(rack)
the instance i hit a pad, the display switches and shows the values i just send…

79

What type of MIDI messages are sent by the KeyLab controls? Could we consider that note messages are only sent when you play on the keyboard ? Or do we also have notes sent when you play on the keypad ? If they do, is there a way to differentiate from the keyboard notes (range of played notes, MIDI channel used… usw :wink:)

The idea would be to restart a display timer when any MIDI control message (any MIDI message different from keyboard played MIDI notes) is sent and to adjust the waiting time such that the display is refreshed at the right moment.

the keypads are “clean” only send control change
you`re german i presume usw
