I'm neither here to discuss philosophies nor to search for a father, explaining me (53yo) something about "logic". "Not recommended" would have been completely sufficient... as sufficient as my IQ.

The purpose of the work-around is to have local keys reach Parts 9-16. When you say "arrangement" - I'm not sure that means you've programmed Parts 1-8 & 12&13 and are wanting to play the piano keys to make Parts 12&13 sound or, which to me "arrangement" implies, you've sequenced something and want the song/MIDI playback to trigger the notes.

It doesn't make much sense unless you're wanting local keys to play those Parts 12&13. So hopefully that's what you're after. If you want a pattern or external MIDI device (including a computer/DAW) play all of these Parts then the loopback is not needed.

Of course to reach Parts 12 and 13 with the loop back, you're going to have to have zone master turned on so that you can make some Parts 1-8 (pick your two) to have the MIDI output channel set to 12 for one Part and 13 for the second Part. Otherwise, nothing will be targeting those two Parts.

BTW: Zone control allows for you to transmit an LSB/MSB/PC. Make sure you have that turned off for this Performance where you're trying to reach Parts 12&13. These are in the Part Zone settings. The reason why I say this is that transmitting bank (MSB/LSB) or PC messages might tell Parts 12 & 13 to change to a different sound. Which is perhaps why you see piano in 9-16.

Since you're only targeting two Parts in 9-16 (12 & 13) - I wouldn't configure the other Parts in 1-8 to transmit to 9 through 11 and 14 through 16. As I suggested before, I would just pick two Performances to enable Part zone control and set those two to target 12 & 13.

@Jason

P.S.: I read it after I wrote the following... " LSB/MSB/PC" ... PC means "program change" ... and the others? Which parts ... the triggeringring ones or the triggered one? E.v. 1-8 or 9-16?

Okay. You never experienced my problem. hm....

Allways hard to find people with my personal problems with the MODX. Main reason could be that nobody does the things I do with it: crafting and playing EVERYTHING, ONLY with the MODX... like an arranger/organ.

Momentarily the most annoying issue is, that the sequencer doesn't work well. Ever tried to record a sequence (pattern/MIDI) with triplets at the beginning? Or a fast sequence of notes? Doesn't function. Triplet-quantize also doesn't function ... neither at the beginng nor at the middle. I mostly do it with a long repetition via MIDI-recording ... and hope to find a piece in between, where it is correct.

I guess that everyone does this with a DAW. And so will I in the future. Therfore people usually don't understand, wht I am talking about.

At least you are treating me as an adult - not like "Things that are unsupported are unsupported for a reason.". I am not retarded!

"Arrangement" is my attempt to translate from German. Ideed it is a french word - which I also speak ;). This means "the whole": song notes, distributed for specific instruments. There are some serious issues when translating German to English, because German has much more words and is way more precisely. We use loanwords - like "arrangement" - in a different/specific meaning. I don't like to and won't use the word "Performance". We understand "to perform on stage"; and nothing else; not what Yamaha means. The collection of sounds, intended to play different tracks of instruments ... we call "arrangement".
If we translate "performance" to the according german word, it means what your car is able to do ... or you. Like in original english;) Of course I will give my best to get such misunderstandings out of the way 😉 So thanks for your question.

So, once again... yes, I did everything correctly. And I assume, that I nearly understand how it works. Perhaps I will try to post some pictures.
7 parts ... part 4 connected to part 12 via Zone Master (Ch12) ... part 5 to 13 ... because they shall come out one after another (by scenes, Kbrd Contrl/Mute). Meanwhile I arranged it a bit differently *lol
The Channels should not be the problem.

I tried to reasearch for this "MIDI-plugging", so to find out technical/electrical problems. No results. The word "loopback" didn't come to my mind. But it seems, noone in the (google-)world has ever done this 😉

Further experiments I did .. with my usual mindset to investigate causes: "pressing much buttons helps much":
- I think I tried out every item with every option ... no result
- even arrange the parts in a different way ... no result

BUT ... I switched off the machine and removed the MIDI cable. Hours later I reinstalled everything again, switched on ... and everything works fine again.
One strange effect remained: the "Utility"-Menue changed the submenue when going out and in again. This hints at a software problem caused by this hack. I strongly assume, that it is a software-problem. MIDI-buffer overflow? ... into a memory-area, where it shouldn't be?
So I disabled ""bank select" and "pgm change" in "Utility". The transmitted things of the parts I didn't change/disable.
But even that "menue-effect" disappeared now.

Nevertheless I don't like this "random" behaviour of the MODX ... which it shows in other corners too.
Let's hope, it holds. Or someone is crossing my way, knowing my described problem.

Thanks Jason

Jason ... you are the one and only *rofl

I researched this MIDI-language I don't speak. By inactivating the mentioned two options in "utility", your LSB/MSB/PC-thing is also disabled in the parts. unfortunately I don't remember when exactly I did so. But I noticed that some things here are only applied after some kind of "refresh" ... pressing liveset again ... or restart the machine.
This hint of yours could be THE point here!

And your suggestion to restrict the Zones to only the parts I want to trigger in 9-16 fits to my assumption of some kind of "data overflow/problem".

My respect!!!

@Andrew

Did you notice, that the problem is solved???

No blaming from Jason ... no further information requested ... instead important information "...Zone control allows for you to transmit an LSB/MSB/PC. Make sure you have that turned off for this Performance..."
"Make sure!" ... that's what I did ... mission accomplished!

Perhaps unpleasant for you, because the problem is gone without a clue what's the difference between "transmit" and "receive". And not capable to recognize, if the software is going crazy by this hack. And not this and not that...

I did it! I simply did what he told me! It's history!:D Yeah, yeah, yeah:D 😀 😀

Are you also active in different yamaha-players-forum? Did I read you somewhere there? Asking for the complete UI parameters available in the whole machine? Because someone was asking about why "no data"-massage when converting to arps? Was it you? Or was it you, who explained what this error-massage means and why and where it comes from ... and what God did on the 3rd day?
Fine, fine ... but this poor guy still had no help in his hand.

I posted directly underneath. I only needed his poor 3 sentences to understand, what's his problem ... INDEED I only needed 6 words to understand: "converting to arp ... -massage". 6 simple words!
I'm doing this day by day by day ... and I know this "no data" massage well ... because I rush through all this and sometimes miss to adjust... adjust what?
My answer was as short as his post. No questions .. no MIDI theory show-off ... no UI parameters ... no blaming ... no parental advices ... just help!
... nothing than "For now change the number of "Arp Track" to 2 ... 3 ... aso.. Somewhere you will find your data. For the future research here and there for further information about that." Finished!

Your answer on my request: "The problem is you are using an unsupported 'hack'." Done! Finish! Short answer ... cool. But not with the following words. Except: wait for Jason.

In this forum there was also a discussion, how "asking people" are treated at some places. Exactly the way you are doing here. The machine is perfect, Yamaha is perfect ... the user is an ... and the only one to blame. Blaming ... very important! ... and so helpful!!!

And now...
Too little information ... unrecommended behaviour ... this ... that ... don't agree on this ... not on that ... do you plan to write a book about my misdeeds?
H E L L O ... the problem is solved!!!!!! I am as happy as I can be!!!!! What do you want from me?????

Is this your way to say "sorry"`? Followed by further accusations? Take your "sorry" and put it in your pocket for the next one!

I can only find two reasonable sentences in the book you wrote about me and my misbehaviour: "not recommended" and "wait for Jason".
The first I registered.
The second I did.

Feel free to critize me furtheron for not acting to your likings or not knowing ... whatever. Problem is solved. "Warm wind" blowing through my hair. Meanwhile I sent an email to an electronic expert in order to reasearch, if there are technical issues with that ... or if it simply causes a mess in data/memoray/buffer/UI. Only for my personal interest.
I will see ...

@Jason

I also found a second effect. All other performances have some kind of "echo/interference". Don't know english words. This must also be adjusted. Either by switching to "USB" again in "Utility" or by also activating Zone in their parts. Channel "off" is sufficient.
First one is faster 😉

It's a special song, that I am crafting/covering here; just to go to the limits, because I found this hack 😉 Normally I have other tricks to come along with 8 parts.

Thank you

Glad I could help.
