Stopping and starting the project returns the kick to its regular sound.
Could this have anything to do with Logic's reset settings for, say, the ModWheel and other controllers?
You know, since version 8, something's has changed regarding that. IMO partially for the good, partially not so much. Just as an example: In earlier versions, when you had "reset controllers" turned off, it'd reset the controllers anyways for virtual instruments (so the function only worked properly for external MIDI modules), but with V8 it does at least not reset some CC messages in cycle mode anymore, namely the ModWheel - I could imagine this to have a certain influence on some other things, too. Just recently I observed some really strange behaviour with another plugin. The preset I saved even refused to sound the same on a preset reload, so I suspect something strange to go on inside Logic, as these things, while being more uncomfortable in some situations (such as the forced ModWheel reset), have at least been kinda predictable in previous Logic incarnations, whereas right now all sorts of strange things seem to happen just occasionally.

(I bet Apple will blame it on the plugin developers, though, business as usual...)

Thanks for the info Sascha, you are probably right ... I'm fairly new to Logic, so I'm not familiar with these kinds of quirks. I've got the mod wheel assigned to filters on the kick, and it is happening on other channels with the same assignment, usually at the start of the cycle point.

Peace,
Andy.

It sure does here still! Where does it not? :-o

I've uploaded a 16bit 44k .wav for you.

Using the initialize preset that now comes with zebra2.3.

Simply playing a very low note then a very high note. Notice how when jumping back down to the low note, the first note sounds like its going through a filter env on the attack, then it plays fine.

Then when jumping back up to the high note, the first high note sounds like it has some aliasing on it, but then the following high notes play fine.

So the sound issues happen on the transition between notes, the wider the gap between the notes the more pronounced the problem is.

I think the problem might be connected with the resolution control on the oscillator. If you set it to max 9, the problem goes away.

If you set it to its lowest 1, the problem becomes really pronounced, jump from high to low note hold that low note down and it stays sounding filter down for about a second!. Likewise then hitting the high note you get heavy aliasing for about a second before it dies down.

*EDIT* Just to expand further on this to try and help resolve the issue, it only seems to affect the first note played after playing one at the opposite end, even if other subsequent notes are played very shortly after.

For example, setting resolution back to 1.00 again for more pronounced effect, if I hold a very high note, play a low note then almost immediately after another low note, keeping them all held down, only the first low note that was struck after the high note, suffers from that wierd filtered down sound at the start, the other low note is not (as far as I can tell affected).

Likewise the opposite way, going from low to high, first high note aliasing, but any other high notes struck even quickly after play fine.

Hi Urs,

Although Zebra 2.3 retains skin (I like the new one a lot) it does not retain the screen size. Is this intended or do I need some tricks? BTW I'm on Leopard 10.5.3 and Live 7.10.

Ah... I understand.

It's a result of making Portamento available for the modulation matrix. Each note is first rendered with the bandlimiting of the previous note. Hmmm... tricky one...

I'm afraid we'll have to release something like 2.3.1 then...

:cry:

Can you render an mp3 for me? Or tell me which specific presets sound different?
Are patches saved to another folder now, or am i missing something?
Nope, it's the right folder. I don't yet have Vista 64 though.

Which version did you have installed before?
Are the patches actually written on the hard drive?
Does closing/opening the editor window bring the saved patches up?

;) Urs
The noise is most obvious on my own patches because sometimes i like
to use some extreme settings on the EQ's. But i can hear it too on
some presets like:

2 Leaders - HS Oh-Ja-Julia
6 Lupins - HS Hand Pots
8 Perkers - HS Fred Flintwood

I didn't hear this noise on earlier versions.

Just recently i've upgraded my DAW to a Vista 64 system. I had
Zebra v2.1 installed on it for a little while and still could see
new patches that i saved in the presets folder. With v2.3 i can't
find them on the hard drive anymore. But they are saved because
they show up in the editor after re-opening.

Ciao,

Any chance you could post up a clip of the noise on those factory presets, and/or a clip of one of your presets + the preset itself, because I haven't noticed any significant noise issues here.

Hey guys,

I think I solved my problems. Up till now I was using v2.3 in
stand-alone mode using Savihost. Then I fired up Ableton Live to
record a few parts, and the noise was gone. So the noise problems
seem to be with Savihost.

Further, I had to fiddle a bit with the permission settings on the
presets folder to gain full control. Now the new patches are visible
again. So probably the v2.3 standard settings, limits access to the
presets folder under Vista 64.

Phew! I feel very relieved now :)

Phewww! Me too!

The noise might be related to another issue which lets Zebra not erase the audio buffers before rendering. I changed the whole buffer/channel stuff in the engine for Uhbik's surround support and must have forgotten to tell synths to not have an input...

Anyhow, I guess we'll have a new update tomorrow, V2.3.1 - hopefully fixing all new issues.

Nice work Urs, thanks so much! :)

First glimpse at Zebra 2.3.1:

http://www.u-he.com/Zebra231MacInstall.zip
http://www.u-he.com/Zebra231Winstaller.zip

- problems with oscillators when playing large intervals at low Resolution settings fixed?
- problems with some odd hosts such as Logic 5 on Windows fixed?
- adds Zebralette presets to Mac d/l
- problems with some odd Mac permissions fixed?
- should fix problems with people who have really short surnames

Any good?

;) Urs
