KVR Audio

Hi.
Since Bigbluelounge.com is not up and running, I had to post this here, hoping that you, Logic users, might be around.
So, I have a M-Audio Ozonic which is my audio interface and my midi controller.
So I assigned various synth functions (virtual knobs) to the knobs and sliders on Ozonic.
The steps I did, I believe are "classic" in Logic: Preferences - Control Surfaces - Controller Assignments - Learn Mode. Then I selected the virtual knob followed by the slow movement of the desired knob on Ozonic. All was done well but when I play the keyboard and turn the knobs some notes are not heard or some of them just hang on. It's like there is not enough bandwith to transmit both midi notes and midi cc messages.
I'm sure it's not supposed to be like this so I hope somebody has an idea what's wrong.
Thanks.

Does this happen on all softsynths or just one? Does it happen if you don't send audio through the device, to reduce the bandwidth requirements?

I don't think bandwidth is an issue here, that would mean m-audio made an instrument that simply doesn't fulfill it's function.

Have you had any other problems with the Ozonic (is it new?), or other problems in Logic with other controllers? It looks like there's either something wrong with your Ozonic (probably not very likely if it's new, but you never know) or your midi is accidently routed in a dodgy way

beej, I'll try to send audio to the built-in and see what happens.
spaceman, the Ozonic is new and, actually, it worked as it should for a few months. But at a certain point I decided to re-assign all the synths I mainly use in a more logical way to the Ozonic. And that strange thing happened.

that is strange. I'll have a look through the settings when I get home to see if there's anything you could accidently change that could cause problems (although I can't think of anything at the moment)

are you testing in one specific project or do you get the same problem in a new project as well?

It's happening all the time...

ok, I'll see if I can come up with something when I have Logic open in front of me. I'll keep you posted

The thing is, after I recorded my performance and tweak the knobs it just works. So maybe it's somehow related to playing the keyboard in real time.

do you mean it works when you're not recording but just playing, so not during transport?

Ok, sorted out!
I'm still learnig Logic

The "resolution of relative controls" was set to 1000. Reducing it made the problem disappear.
Interesting to know.
It is still not very clear to me what this function does (or how it works) but this was the problem.
Thanks for your support, guys.
And, by the way, do you happen to know what is de midi cc number of the pitch bend?

Weird...
after playing a bit the problem reappeared.
Now it doesn't react to changing the resolution value.

I'll give you the right settings when I get home. If that doesn't work we need to look in an other direction

so do you only get the problem while recording?

btw.. I don't think pitch bend is transmitted on a specific cc channel but in logic you can remap pitch band to cc (do a search on google and you're sure to find an article, like this)

Thanks for the link.
I found out that it's midi cc 144. At least on my keyboard works when assigned to this number.
Good to know.

Logic and midi controller weirdness.
