Zebra 2.5 Released!

[hakey]

XMF Filter FM seems quite noisy in 2.5 when compared with that in 2.3. Is this deliberate?

It isn't deliberate. I've been sweating over this but couldn't figure it out yet. It's either "one of those bugs" or it's just, well, it. I remember that the original XMF's resonance was so extreme mostly because of the FilterFM. So I'm a bit concerned that maybe smooth FilterFM is going to be a speciality of the 2.3 mode. However, I'll look into it again and again for another couple of weeks.

Oh, okay. Sorry to have brought it up - it sounds like a difficult problem

My 2c: It would be really nice to have clean FM in 2.5. After all, isn't the raison d'etre of the XMF audio rate FM (and self oscillation)? As it is now the FM knob (in 2.5) isn't all that useful - it's not really what I'd call audio rate FM, rather it's something more like a distortion/noise-modulator knob.

As you say, switching to 2.3 is a work around, but it's not such an elegant solution and might not always be convenient, for example, where a patch has already been built in 2.5.

That said, don't sweat it too much

Yes, of course I know that the current state isn't ideal at all... I'm also quite certain that there must be a bug somewhere, because FilterFM in Bazille works rather well and the code is very similar.

Thanks for the link to the old post. Useful to know, especially as it adds two flavours of ping-pong...

I just dosed over that and started wondering how to work out a proper ping pong delay mode.

What is the delay time of the feedback path in a typical ping-pong delay with 2,3 or 4 taps?

- A + B + (C) + (D)
- the longest out of A, B, (C), (D)
- just A, and B, (C) and (D) tap it from there

I put C and D in parenthesis to show that they're optional.

Hello Urs,
you're asking the wrong person, I have no idea...

As far as I know, ping-pong delay is just summing the signal to mono, delaying that by X and the repeating it panned alternately hard left and right by X time.

I could well be wrong about this though, I'm a musician rather than a plug-in designer.

Thing is, both the setup that you posted and the one I stumbled upon both sound great as ping-pong delay and do the job that I descibed perfectly.

So, if there was simply a button or mode switch that simply set the delay parameters "under the hood" of the delay to the positions in your posted pic. then that would work.

Cheers,

I thought it was, when the server tricks the receiver into thinking the balls coming back sooner than it does.
Yes?

I can't seem to get duophonic mode working. It seems to remain in mono when I have duophonic selected. Is there something I could be missing? Using the mac VST of b6 in Ableton.

Also, it may have been mentioned, but the AU of b6 fails the AU validation in Logic.

cheers

Actually, this was fixed. You just need to re-download from the first post and it should pass validation fine.

[Urs]

Also, a couple of more fixes are on their way. Might upload later today or tomorrow

keep 'em coming

Out of curiosity, is the main reason for 2.3 and 2.5 mode just the XMF filter?

If so, why not just have XMF+ and XMF2+ or something like this and have them as new modules?

I'm probably missing something, but I just thought about this when I was taking a shower :p

Not just the XMF... also several of the VCF filters have been adjusted in sound and volume... and of course all types of oscillators and their modes are now amplified to the same level, allowing for more overall consistent editing.

Some more things are going to happen still, e.g. drop Comb filter's "Cluster" mode for something editable.

The 2.5 mode allows me to get rid of some "brownfields" that came in by accident over time...

Hi Urs,

what do you mean by "brownfields"? "Braune Felder" makes no sense to me...
Do you mean less elegant code?

stay tuned

Brownfields means "Altlasten", or areas of polluted soil.

There are many things that I wished I had done differently. With 2.5 I can correct some of these, e.g. the notoriously instable Highpass filters and the annoyingly loud LP Allround (which for some is now the best sounding filter in Zebra alltogether).

Hi Urs,

For some reason, I can't get the "fundamental" oscillator effect to amplify the fundamental. When it's in the middle the fundamental disappears, and on either side it only get as loud as it originally was. I don't have an earlier version to compare (using 2.5 b6 right now), but I don't think this was the usual behavior.
In the annoying "this is really cool but it doesn't have this category", it would be really useful if the LFOs had a "symmetry" control and an option for not passing through the original value but only adding to or subracting from it. The Synton Fenix, for example had options like this. I know you're not planning on adding anything new to this version but thought I'd throw it out there anyway, and sorry if there's already a way to do this that I haven't figured out yet. Also, I was wondering if there is currently any way to get the arpeggiator to function monophonically?
Thanks for all your hard work, this thing is sounding pretty rad...

I liked the LP Allround filter before, but now...
