That's cool that you can copy the curve! But forgive me by dumb question, how to retrigger the mapper like an MSEG with and ADSR like behavior?Urs wrote: Mon Jan 05, 2026 1:35 pmHave you tried to copy & paste an MSEG into a Mapper yet? For evolving and particularly for LFO-like MSEGs this might be a quick fix.midi_transmission wrote: Mon Jan 05, 2026 12:01 pm Just my personal opinion, but I realized my favorite solution is just more MSEGs. For soundscapes or complex pads it's doable to hit the 4 limit. But yeah, maybe I'm too used to Absynth.![]()
That said, the mapper is really really cool on it's own! I would definitely like to keep these 4 mappers. Super fun to use for all kind of modulation and the workflow is moving you to different results than MSEQ or LFOs!
So my wish is still to have just more MSEG and/or to have MSEQ "mode" also in the mapper (the difference would be that you have steps in the MAPPER and a Shape in the MSEQ.

Will Ctrl A - D be able to be mapped to a MIDI controller / Midi Learn in the future?

Some “issues” I’ve been noticing. I think these have been talked about already but just wanted to add support to those issues:
It’s definitely hard to tell what knobs have modulation sometimes. You have to go the Matrix and then click/move the mod knob to see the destination.
The Poly/Mono/Legato highlight doesn’t change when you select a different option (bottom left)
Having the ability snap to specific spline shapes would be helpful, or being able to just click on the images above the editor to select a certain spline shape. For instance if I want to start with a Square wave, I have to turn the knob and carefully select it perfectly.
I know we can set up duophonic mode but I loved how easy it was in Z2 (just a selector). I think a lot of people will miss that option.
Right now, 100% view mode gets cut off the bottom of my MacBook Pro. Being able to grab the corner to adjust the size would be great.
Please add the arp/sequencer back!
I wish the matrix section was bigger, as in the modules, they’re kinda tiny right now. Same with the effects.
BUT the most important thing is it sounds great.

They *are* MIDI Control Changes. We're actually trying to make them into normal parameters as well, to suit workflows with DAWs or control surfaces that are not MIDI-centric.stippenstoh wrote: Fri Jan 16, 2026 3:58 pm Will Ctrl A - D be able to be mapped to a MIDI controller / Midi Learn in the future?

Thanks Urs, I am just a regular noob, I see knobs that look like keyboard controllers but I can't map them to keyboard controllers

Pretty much all of these issues will be addressed, most of them for initial release or even in the next beta.
Double Click a curve in the time line to set CurveMorph to that waveform. This works already.
Duophonic mode will be available via templates and tutorials only though. Maybe we can add it in a special drop down that switches the preset to certain configurations. It's something I've been thinking about, but we haven't done it yet, so can't promise anything.

Hehehe, not dumb at all. I have to think about it. You still need some kind of linear MSEG or slow LFO that drives those... maybe I haven't thought that through enough... yet... might need a tutorial...midi_transmission wrote: Fri Jan 16, 2026 3:48 pmdumb question, how to retrigger the mapper like an MSEG with and ADSR like behavior?![]()

If I'm understanding you correctly, you might want to check out the preset I posted here. It has an MSEG controlling a mapper to mimic the quantized amplitude envelope of a Casio VL-1.

I’ve done that before but for fast quantized pitches. I forget was vintage synth it was, maybe the Sid chip, fast pitch changes are stepped so I used the Mapper to step the pitches
Also I think some other vintage synth, the saw wave is actually stepped Squares since the chip could only produce square waves

Well, it's not that simple to create versatile modal profiles. I tried, and yes, Python helped with prototyping and understanding what those profiles do. But I haven't even scratched the surface. It's one of the Zebra 3 parts that I would definitely like to play more in the future. Please leave the CSV import for profiles, it's a very cool idea.orbitfold wrote: Fri Jan 16, 2026 12:28 pmI prefer CSV considerably to a GUI option.

No worries, we won't change it. We made that decision some time ago, and this is it.
We might eventually publish software that creates such profiles, e.g. in a dedicated Modal Synthesis plug-in, or as part of an analysis tool.

Great idea! Also, I’ve noticed using Cthulhu that I’m able to create legato even if midi notes don’t overlap in Zebra…but they have to be touching, while in Serum, the midi notes have to actually overlapUrs wrote: Fri Jan 16, 2026 7:30 pm No worries, we won't change it.

Is this a mistake or by design? It makes it actually more useful in Zebra actually!

Just got into the demo of Zebra 3 the last days and really love it. I was pleasently surprised on how easy it is to create organic sounding drums, sfx and pads. Reminding me a lot of that analog diva sound. Can't wait for the full release.
A few questions and feedback I got:
1.) The modal engine quickly became one of my go-tos for creating organic impacts and sound design. Is it planed to add more modal profiles on release? More drum and percussion focused presets as well as further instruments resonances would be really amazing.
2.) I would love to permanently have indications on what parameters are modulated by what. Currently these highlights vanish for me when re-opening a patch and I have to go to the matrix view again (which is visually hard to parse) or double click MSEGs to pull up the hints again. It would be amazing if these displays could remain visible by default, maybe color coded in a way to quicker get an overview what is going on in the patch. Maybe there already is a possibility for this which I did miss.
3.) A tooltip system would be very helpful in displaying a bit more information about the parameters. I think this would ease the process of learning and getting into zebra3. This system would even allow for interactive tutorials that could widen the potential audience for zebra3 as I think making this deep synth accessible to new users will be challenging.
4.) Is a fully flexible rescalable UI something that is being worked on or planed for the future? On some displays (also with other Uhe synth UIs) it would be amazing to have further flexibility aligning the UI with a simple window scale drag.
5.) Is there an option to lock the analyser wave form to a static wave instead of a moving wave a bit like the wave analyser in DIVA?
6.) Is an alternative ADSR module/ mode planed that allows to create non linear ASDR curves? Or is there a way to use an MSEG as main envelope of an OSC? This would be amazing for designing impacts.
Thanks in advance. Keep up the amazing work.
