Zebra 3 Public Beta 3 Revision 20977

[pgwalsh]

Linux build will follow asap, we found some last-minute gremlins.

Will be looking forward to it.

My fast feedback:

1.) Scrolling during MIDI learn does not work. Is it intendend to be changed?
2.) Horizontal scrolling of modulations: Behaviour much improved (already since laste version), but: Can it be implemented to enable scrolling also when the mouse pointer is on the modulator's "mute-number-delete" tab? There's not so much place beside all the scroll-sensitive GUI-widgets and this would be a nice screen estate to react on scrolling wheel for horizontal scrolling.
3.) I had it once, that not all widgets for MIDI learning were marked with frames. After change from tab synthesis->pitches and back it was healed. Not reproducable until now
4.) During MIDI-learning: change of tabs, e.g. Synthesis->Pitches, Pitches->Synthesis, P or S->Presets changes to the new page, but midi learn frames do not update according to the new page. Frames are kept from page, where MIDI learn was initially started.

I'm not sure where to post this, and i understand we are rather beyond introducing totally new features,
but i would love an FX module that is dedicated to feedback:
I'll explain: i was trying to make some dub style effects that often have feedback chains combining feedback with say a phaser and other fx in the feedback loop. I can put a delay and phaser in series, but it's not the same. So an fx module call it 'teleport' lol. teleport 1 sets a point in a chain where a feedback send is created, teleport 2 module is the receiving end, this one can maybe have a feedback intensity/ + dry-wet knob. Ideally some kind of Tanh limiting curve oe clipping with treshold for keeping the runaway fb in check.

I'm not a coder and not sure how tricky this would be to implement, as it might mess with the linear audio processing sequence & path. But maybe a nice idea for some future time?


Only had 5 mins with the new firmware yet, but the ringmod is now displaying its frequency in Hz. kinda cool but before i knew that values like 24, 48 for example had a 1_1 ratio when tracking pitch. I kind of miss that. You can ofcourse do it by ear, but before, values & multiples of like 5, 7, 12 like in pitches allowed you to know the kind of stable centres quickly.

Feedback of what? Delay feedback? Are you taking about a comb filter with feedback?

Oh also, why isn't there a curve shape for a pure sine wave? I know you have sine-o-matic but it doesn't seem to work all the time. Especially if you're adding the sine wave shape to small areas

you can use the OSC editor to create a perfect 1 cycle sine. The editor has tools for the most basic shapes

It's not a perfect sine, it's slightly bent

You are right. some extra harmonics @ -30dB...hmm.

the FMO module has a perfect sine (the carrier). weird

Yea I'm sure Urs knows about this but I think it's a perfect sine if you use sine-o-matic but there should def be a perfect sine shape to use.

This is great!! So many new presets and tweaks to try out! I cant wait for the full release, and thank you! Much faster startup time and GUI loading time.

I notice: some audio glitches in this new build that were not present in previous builds. For example, the very first preset, "4 notes of acceptance" (one of my favorites!) with nothing in the signal path but a limiter is peaking at 100% CPU briefly, causing a small audio dropout in cubase 15.

Same blank project in Bitwig beta 6 or stable 5, same signal path, same Zebra3 preset (4 notes of acceptance) does NOT peak to 100%, does NOT glitch audio. In fact BWS's internal CPU meter shows very low CPU, barely above 7 or 8% and very consistent.

Same interface settings on both. No ASIO guard on cubase. Sandboxing in BWS set to "by plugin".

Set Source to Curve Spectrum and use just one partial... that makes a clean sine

You are right. some extra harmonics @ -30dB...hmm.

Dunno what you're talking about... make a triangle, do "Sine-o-matic" and you get an at least -80dB perfect sine...? Requires Precise maths though, which are not required for, say, saws and squares...?

[paradiddle]

Thank you for the update! I tried the filter 5/6 in the fx block at the bottom and It seems that clicking the WIP doesn't pop up the menu or so? I am able to change the filters though.

I get -60dB

That's with Fast maths... or maybe it's frequency dependent, dunno, I can check tomorrow.

Sin-o-matic gives the exact same results. Just a high precision sine osc on it's own will result in some minor extra harmonics (not at -30dB but at -90dB, which is clearly near silent. However, when using the FMO, the carrier sine has 0 extra harmonics).

tbh..i don't care about those harmonics. Was only saying that the OSC at it's highest precision isn't completely clean. Which is fine to me

[DrWashington]

Holy mackerel, this sounds brilliant. Can't get over how much I like the "yellow" filter. I think I recall Urs mentioning it was based on the Wasp's. True? Is there anything different about the architecture?

As sort of an aside, I had a Korg Z1 for many, many years. Certain patches just really got lodged in my brain and have caused me to miss it quite a bit after I sold it before moving to Los Angeles. But most of them were kinda mediocre. One that absolutely was not was "Digital Dulcimer": just a super, super rich, euphonic sound. Haven't found anything that can recreate it perfectly yet.

If anyone's familiar with this one, is Zebra 3 a contender? Any ideas on what to do? Not sure how deep the physical modeling goes yet, but certain characteristics of this thing remind me of the Z1 somehow, so I thought I'd ask.

[DrWashington]

Also, is there a reason the Ctrl A, B, C, D knobs aren't MIDI-learnable? Is this something that's still being worked out pursuant to the "special note" in the changelog?

Edit: would also love to have the ability to set MIDI Learn min & max, like the venerable old z3ta+ used to support, among others. I found this incredibly useful for being able to have the full 7-bit MIDI CC range available for JUST the sweet spot of a given parameter. It would be fine if it was just in the "T" page.
