Understanding SysEx-handling and EVENT_RECEIVERS

MIDIbox NG
1

Hey people,

my controller has 9 OLEDs which I want to address via SysEx, which works good. Here is the code:

EVENT\_RECEIVER id=1 type=SysEx stream="0xf0 0x00 0x31 0x00 ^txt" label=&a lcd\_pos=1:1:1 EVENT\_RECEIVER id=2 type=SysEx stream="0xf0 0x00 0x32 0x00 ^txt" label=&a lcd\_pos=2:1:1 etc.

Each OLED has it’s own ID (0x31, 0x32, etc.). 

What I now try to change is the stream that the OLEDs listen to. So I set up another set of receivers:

EVENT\_RECEIVER id=11 type=SysEx stream="0xf0 0x00 0x41 0x00 ^txt" label=&a lcd\_pos=1:1:1 EVENT\_RECEIVER id=12 type=SysEx stream="0xf0 0x00 0x42 0x00 ^txt" label=&a lcd\_pos=2:1:1 etc.

I use some buttons to “set_active” the different receivers. So the NGR reads:

if ^section == 1 set\_active (id)RECEIVER:1 1 set\_active (id)RECEIVER:2 1 set\_active (id)RECEIVER:11 0 set\_active (id)RECEIVER:12 0 exit endif if ^section == 2 set\_active (id)RECEIVER:1 0 set\_active (id)RECEIVER:2 0 set\_active (id)RECEIVER:11 1 set\_active (id)RECEIVER:12 1 exit endif

I’d expect that with this code I can change the stream… but I can’t. They are listening to all streams at the same time no matter if I “set_active” those receivers or not.

I thought that it might be related to the receivers. So I changed them out with EVENT_LEDs but same here. I can not achieve, to switch between those two SysEx-streams.

I also tried the “set_lock” command… but that was also not working. I also tried button the receivers in different banks and change the banks with the buttons => no success.

So… what do I overlook? Is there any solution for my problem?

Thanks,
Chris

Hello Chris

Not sure to get it all, but I see your first set of receiver (1 to 9)  print label to oled 0x31 to 0x39 but your second set (11 to 19) don’t print to the same oled ID, 0x41 to 0x49 ?

Thanks for your hint!

But I think you are not right here. The ID doesn’t matter because the oled is set with the parameter lcd_pos=1:1:1. This also does not explain the behaviour, that I described above (both displays listen too all streams at the same time instead of only two streams).

Hello

 

Yes you’r right.

Did you try another strategy, like no script(NGR) involved but conditional at NGC according to your flip button

EVENT_RECEIVER id=2 type=SysEx stream=“0xf0 0x00 0x32 0x00 ^txt” label=&a lcd_pos=2:1:1 if_equal=button:1:0

etc…

EVENT_RECEIVER id=11 type=SysEx stream=“0xf0 0x00 0x41 0x00 ^txt” label=&a lcd_pos=1:1:1 if_equal=button:1:1

EVENT_RECEIVER id=12 type=SysEx stream=“0xf0 0x00 0x42 0x00 ^txt” label=&a lcd_pos=2:1:1 if_equal=button:1:1

etc…

EVENT_BUTTON id=1 range=0:1

I don’t have explanation for your issue, but maybe it’s linked to label= handling, I mean it’s not a midi function/data, so it is forwarded to LCD anyway ??? just an idea…

 

Can you try to set a fwd= to anything from your receiver and check if it effectively forward midi event or not, depending of set_lock or if_equal= status of the event ?

by the way… what is supposed to print &a ?

(sorry i’m not use to label… never really add LCD to my midibox and &a is not in the current user manual at label=)
