Convert Sysex String to NextSong-message

[Trebor]

Hello,

is there any way to make a Gig Script that converts an incoming Sysex-String to a message that switches to the next song?

I use a Roland AX Synth to control VSTi-Synthesizers as a Plugin in GigPerformer.
I have no controllers left that I could use to switch to the next song, so I want to use the V-Link-off button to switch to the next song. That actually sends a SysexString (F0 41 7F …).
I cannot use Program Change messages as these also switch the built in sounds of the AX-Synth that I also need for my performance.

Any ideas how I could do that?

Thanks?
Nils

Hi @Trebor, welcome to the GP community forum

@jeffn1

Does this help?

It only helps if @Trebor has enough programming skills to adapt the Gig GPScript. But indeed, it is exactly the right thing to do. The idea would be to convert the SysEx into a regular CC# which can be used to learn anything as any regular controls.

@Trebor, if you have difficulties to adapt the Gig GPScript for your own needs, please come back here and ask. And if it works for you, please report your success

Indeed, an older version of the exact same approach:

@David-san

Thinking about it, I should probably only convert your sysex into CC by adding the following code into your gig script editor:

On SysexEvent(sysex: SysexMessage) From Focusrite 
 Select
   sysex == "F0 43 70 78 41 53 01 F7" Do InjectMidiEventViaRigManager(Focusrite , MakeControlChangeMessageEx(20, 127, 1));
   sysex == "F0 43 70 78 41 53 02 F7" Do InjectMidiEventViaRigManager(Focusrite , MakeControlChangeMessageEx(21, 127, 1));
   sysex == "F0 43 70 78 41 53 03 F7" Do InjectMidiEventViaRigManager(Focusrite , MakeControlChangeMessageEx(22, 127, 1));
   sysex == "F0 43 70 78 41 54 01 F7" Do InjectMidiEventViaRigManager(Focusrite , MakeControlChangeMessageEx(23, 127, 1));
 End
End

Hence you will be able to MIDI learn the button of your old Yamaha controller to any GP widget. Set your widgets to “momentary to lacthing” in the widget properties, as with a single state SysEx message the only thing you can do is to toggle widgets.

Tell me if it works for you?

Great stuff. This probably will help. Regrettably its my wife’s birthday. So I am not allowed to do any synth stuff today.
I’ll let you know the outcome asap.

Thanks again for your input. That was really helpful. In fact I was even able to skip that MIDI-learn bit by using NextSong(). I used this in the Gig Script:

Var AXSynth : MidiInDeviceAlias;

On SysexEvent(s : SysexMessage) From AXSynth

Var sysExString : string = SM_Pretty(s, s.SM_Length(), True);

Select
    sysExString == "F0417F0051121000 000070F7" Do NextSong();
End

End

What I primarily did not get is that I had to define the MIDI-device (in this case “AXSynth”) in the Rig Manager as a MIDI Device alias.
Anyway - now it perfectly works.

@Trebor

Var AXSynth : MidiInDeviceAlias;

On SysexEvent(s : SysexMessage) From AXSynth

Var sysExString : string = SM_Pretty(s, s.SM_Length(), True);

Select
    sysExString == "F0417F0051121000 000070F7" Do NextSong();
End

End

Unless you’re using an old version of GP, you don’t need to do that string conversion. You can just write

Var AXSynth : MidiInDeviceAlias;

On SysexEvent(s : SysexMessage) From AXSynth
   Select
       s == #F0 417F 0051 1210 0000 0070 F7 do NextSong()
   End
End

It’s probably my fault, my GPScript programming style has survived the ages and left its mark…
