Very weird problem in Renoise 2.0 final

Wew, this is a real corker, haven't heard of this problem before:

Whenever i load an instance of Zebra, the cutoff of the loaded Zebra instances seems to rise, untill i switch a patch of the newly loaded Zebra instance.

Example: I've got Zebra on channel 1 playing a few notes, and i've got another Zebra on track 2 playing a few notes. Then when i load up another instance of Zebra, the Zebra's in track 1 and track 2 sound very bright and sharp all of the sudden, like their cutoff's got raised a few notches. Then when i select a patch (any patch) in the new instance of Zebra, the cutoff of the first 2 Zebra's goes back to normal.

It only does this when loading a new instance of Zebra, not when i load another plugin, not even Zebralette.

Now i'm wondering, what's the right way it should sound? Does Zebra sound like it should sound when i load the new instance, with the raised cutoff?

I've tried making a new Renoise project with nothing but 2 Zebra's, no effects or other VST's whatsoever, and the problem persists. Here's a download link to the Renoise project in question:

I don't know wether the problem is the patches, Zebra or Renoise :/

Here's my specs:
- Renoise 2.0 Final (registered latest version)
- Zebra 2.? dunno but it's the latest registered version (no beta).
- Vista latest service pack + updates
- Athlon Phenom quad core

Urs, if you have no clue, i'll re-install Zebra and Renoise, and see if that makes a difference. I haven't bothered to reinstall everything, it would be kind of a chore, especially if you know an answer to this from the top of your head.

Thanks in advance! Lots!

*EDIT* i've just tried the following, without result:
- switching to a different ASIO driver
- switching to a different buffer rate
- switching to DirectSound
- turning of automatic PDC

No effect :(

Just tried this here running Renoise under Wine on Linux and can't reproduce it.

Thanks for trying! If URS know no real answer to this from the top of his head, i'll go the rout of reïnstalling Renoise, Zebra, and probably my soundcard drivers. Boy, am i glad it's weekend :)

Thanks again!

I just managed to make .WAV samples of this phenomenon, 2 samples each with a different cutoff, one sample is 2 Zebra's playing when the song is loaded, the other sample is the 2 Zebra's playing with a raised cutoff due to loading a third instance of Zebra. You can find both samples here:

before:

after loading a third instance of Zebra:

You can clearly hear a difference in cutoff between the two.

(but today I'm in perfect weekend mode... having a hang over and building my Christmas present)

Somethings going on here too adding new instances changes the previously loaded instances in Live 7.0.14 on XP.
At first i thought it was the transpose bug but not sure now some values are defo going up.

com.u-he.Zebra2.midimap=

// Global MidiCC Map

Just checked changing the new instances preset resets the first back to normal, thanks for that not quite as annoying now.

I noticed this in Live 7.014 too. I had an instance loaded with XMF cutoff tracking the keyboard. When a second instance of Zebra was loaded, the cutoff on the first instance was higher. When I created an XMF module in the second instance everything went back to normal.

Great!

I can confirm that this only happpens with the XMF filter now. Just tried it with that .xrns file i made, changed all the filters to anything but XMF and the cutoff problem when loading a new Zebra instance does't happen anymore.

Man i gots to get me some sleep now. An all night bender with my sister, i'll pribaly read about this tomorrow never knowing i wrote this.

Jekyl & Hyde stuff :D

I'm scared to work on any projects as most contain 12+ Z2 instances,assuming that the false value get saved by the host? this is a show stopper.

Post

To everybody who's experiencing this: Are you on 48kHz?

I found a possible chance that the XMF would be recalibrated to 44.1 kHz if a new instance is opened where the XMF isn't used.

Actually, ouch... this may very well be :-|

I'll be uploading test builds with a fix shortly...

The good news is, the patches are all saved correctly :)
