Grandorgue key randomly pressed

hi,
i'm trying agan to solve an issue with GO and i have now some new infos for your suoport
Brief description of the issue
when i press keys on mi midi keyboard some / many of them get pressed without releasing i have to press them again (sometimes more than once) to have them off. This happens on windows and on Linux, i'm using different pcs with same issue midi keyboards are on a Johannus sweelink 30 organ.

At the time of the first post past year i issue was related to the cable or more probably to the latency. i tried to change configurations, following your suggestions, but the issue was never fixed so unfortunately i gave up trying to use GO.

Well, recently i connected an iPAD to the organ to test a free app named JeuxdorgMini.
Issue was exactly the same but i found a setting called "Check note messages" . I disabled it and whoila' the issue disappeaed !!
I know there was an option in GO to set MIDI event log on and off. When it is on, it gives exactly the same message as with JeuxdorgMini ! My hope was to find that option enabled by default... This is not true unfortunately. I looked for similar setting unsuccessfullly.

The question is this: does it exist some option (hidden tomme) that forces GO to log event messages like Jeuxdorg? If yes, does it make sense to you trying to disable it (or any similar option) to fix the issue ?

thanks in advance for your help . I DO wish to solve this issue and start using GrandOrgue !

regards
Paolo

Hi,

I am the develoepr of Jeux d'orgues Mini. If the problem goes away when you deactivate "Check note messages", then the only explanation of the behaviour is that there is a channel conflict, i.e. both keyboards of your console use the same MIDI channel. Or maybe the console sends double messages if you use a coupler (of the console) and then press the same note on two keyboards. Use a MIDI monitor on Linux or iOS to check this.

Regards,
Markus

The meaning of that option is explained here in General – Behaviour:

GO has a log MIDI event option in its audio/midi menu - logging MIDI events should never change the behaviour.

There is probably something broken on your MIDI setup. I don't remember reports about broken Johannus organs, but multiple reports about broken cheap USB MIDI interfaces.

Supporting broken setups is out of scope of the GO project - but the powerful MIDI matching captibilties allow some kind of workarounds: You can configure multiple MIDI events (eg. for listening on multiple channels) or match all channels, .... But the first thing is to understand, what kind of error is in your MIDI signals.

markus, martin appreciate your quick reply .
on ipad i have enabled a midi monitor and i noticed that when issie arises on JEUXDORMINI
(with "check notes messages" option enables) the channel often change but when that option is off
the channel , for each keyboard (i have three on my Johannus organ) are the same numbers (1,2,3 corresponsing ro the three manuals).
I suddenly recalled a post i sae on this forum i suppose where it was siggested to set "all channels"
in midi sertimgs in grandorgue.
I dis this: in GO i did right-click on eqch keyboard and changed the channel from "1,2,3" to "any"
Issue seems fixed ! i was able to play at any speed without having any key pressed !
tomorrow i'll go on testing.
can you explain ?

Hi Paolo,

what do you mean by "the channel often change"? Does one and the same key of your console send on different channels? Does it send a note-on on one channel and then a note-off on another channel? By the way, can you set the channels at your Johannus organ?

Markus,
no i can't set channel on my Johannus organ. I'm going to double check the manual
but i'm pretty sure i can't.
As per the channel change, it looks like that pressing keys on a leyboard very fast or pressing some together the notes-off corresponding to a notes-on happens on different channel.
i want to check on this once again because, if true, seems illogical to me: in fact, the three manuals have three channel assigned by default (1,2,3). i suppose a notes-on event on ch1 should have a corresponding notes-off event on the same channel. when this does not happen, the key remains presses.
What i discoveres yesterday evening is that if i set each organ manual to "any" channel other than specific channels 1,2,3 seems to solve the issue.
i'll dig into this to find the best configuration in GO. i'll look carefully this forum as well as GO instruction.

What MIDI interface are you using?

Look at the GO MIDI monitoring. My guess is, that some MIDI events with the wrong channel are received, which mean that something is broken at your site. In my option, its more likely, that you have got such a broken USB-MIDI interface than that your organ is broken.

i got this one : AGPtek USB-MIDI. For sure not expensive at all (ithink nomore than12€).
I may suppose a professional (if any) cable could give better performances ... neverthess,
i tested it with jOrgan, Cantabile and other and it works.
The "key pressed" issue arised only with GO on pc and jeuxdorgmini on ipad ; now it seems solves
in jeuxdorgmini by unsetting "check note messages" and in GO by setting "any channel" in each keyboard.
past days i had no time to go furher with testing: i'll be back soon.

i made some more testing: definitely, setting channel to "any channel"
does fix issue and keys don't remain pressed ant more.
Now i can optimize configuration and start play seriously with GO !

So AGPtek USB-MIDI is likely a broken MIDI interface ["buggy firmware"].

ok. in that case , please could you suggest a good one ?
I see online markets offer many of those, varying from lowest to highest prices, Maybe you may suggest the best option for GO.

Martin, i'm still back after a pause due to heawy work.
i went ahead with testing: pls look as follows...
if i use all 3 manuals in my johannus organ, before or after i get
the issue that is ramdom keys stay pressed on the manuals.
last time i wrote that setting "any channel" instead of 1-2-3 corresponding of course to the three
organ manuals did fix the issue. i confirm this i mean, no more key pressed ; however there is another issue doing this way, that is manuals 2-3 become merelt "clones" of manual I ! they are no more indipendent and play like manual i (same stops); basically, it is like to have and use just one manual.
i made a final test, that is i set in GO only one 'manual' with its proper channel 1 (NOT "any channel" but at the same time i didnt activate the other two manuals via midi . definitely, only one
keyboard via midi. as a result i didnt get the issue, no key pressex...

once again, in your opinion where the
problem is ? cheap broken agptek midi interface (buggy firmware?) or something not working properly in my JOHANNUS organ MiDI internal circuit ?

hope the first: it would be just a matter of pur hasing a better midi-usb cable !!!

if the second, i would have to call JOANNUS support and this se second soluttion is
much more difficult to achieve

I have multiple reports about broken USB MIDI interfaces showing similar behaviour.

I would suggest to ask other GO users, what USB MIDI interface work for them (on the OS you use).
