Weird CC send behaviour with midi control send

BobTheDog

Hi Guys,

I am getting something quite strange here, when I have lots of midi control send modules linked by the yellow send/receive pairs the G2 starts to loose resolution on the CC's it sends!

I have included a large controller patch all the CC sends on this patch only send a few cc messages per second.

I have set up a couple of modules to show this, they are called noSend and send and are on the right of the VA section.

NoSend is not linked and send is linked, I have mapped the knobs to the filter 1 page knobs 7 and 8 on the g2.

If you run a midi monitor app (like midiox) and twiddle the two knobs (or do it in the editor) you can see the problem.

Does anyone have any idea whats going on here?

Cheers

Andy

Hi Jan,

I dont't think it is anything to do with the capacity of the midi line as it is not being overloaded.

The problem is that the CC send module sends limited messages if a wire is connected to the logic send input even when the logic signal is at 0. If I disconnect the wire to the logic send input the module then send the correct number of messages.

Did you try the patch?

Cheers

Andy

I never found a use for those logic in/outs, so I never connect them.

Hi Ian,

They are useful for sending all the cc's when you change variation or load the patch, this works fine in the patch I posted, apart from the undesired side-effect of making the controls useless!

Cheers

Ok ... this is fishy ... and it shouldn't be that, there is no other disturbing MIDI traffic at all and it sends much less values indeed. Seems a bug to me, or at least an interesting phenomenon, like fun for Clavia to look into Very Happy

Funny thing is that when I strip the patch down to leave just one CC send in (and the Status module) the problem doesn't seem to be present or much less present at least. As if the whole chain of CC sends is evaluated even when only the last one changes value and nothing happens on the yellow lines.

Edit, forgot : when I leave in all the modules but break the yellow hain to have onl the last CC send connected to the Status module the drop in the number of values sent is still present, so it seems related to the number of CC send modules, and not so much to how they are chained.

Hi Jan,

Do you think I should report it to Clavia then?

Cheers

Seems a good idea to me to report it to Clavia, yes, I had meant to type that ... hmm another thing I forgot ... wonder where my brains are ...

Ok Done it, lets see what they have to say.

Hi Guys,

I just got this in response from Clavia:

Hello, thanks for your report, I will take a look at this. For the time
being there are no updates planned for the G2 so im afraid I cant give you
any hint when this can or will possibly be solved, take care

But at least it sounds like a confirmation that its a bug ...

BobTheDog · Posted: Thu Jun 15, 2006 3:26 am Post subject:

Looks like it.

I will change the patch to move more of the modules into the FX area to see if that helps.

Cheers

Andy

Hi Jan,

The problem is definately when the modules are linked.

I have included two patches.

bugtest_unlinked : Here we can see the resoultion of the midi send modules are fine, there are two being set by the lfo we get lots of resolution.

bugtest_linked : Here it is bad, the resolution is terrible. But it get worse. If you turn the lfo control off with the switch and twiddle the knob on the u-manual control (right of the lfo) you can see the resolution is fine. If you twiddle the linked l-manual control you don't get anything at all, the G2 is sending nothing!

cheers

Andy.

Andy,

after testing I can confirm what you wrote and it seems like a pretty accurate problem description to me.

I'm about to move this thread to bugs section, unless some one has problems with that.

Hi Andy,

I have no problem, it seems like the place it should be.

Cheers

Using my G2s a lot for midi controlling I've observed this bad limitation many times.
Please note that there's sort of workaround for this.
The problem seems to be much less present if you turn patch to monophonic, or you move as many as possible ctrl send modules into FX area (that is monophonic).
Still this is an annoying bug in my opinion.
