Which Windows version and DAW did you use?
Still cannot reproduce, looks totally fine on Windows over here.

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.
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...?
Thanks Urs. Is it possible to add a perfect sine shape to the toolbox?

Sine o matic doesn’t seem to work if I want to add multiple sine shapes into 1 curve

I’m still pressing for key following for the Sample rate reducer distortion module so we can have harmonic upper partials that track with keyboard like with the PPG

Not mathematically possible. Our sine accuracy exceeds that of any paper I found about reproducing a sine with cubic Bezier splines.

You can theoretically get closer by using more than 2 curve segments. But I did not bother, because 80+ dB is pretty much inaudible already, and beyond CD quality.

Sorry, we're not adding any more features at this time. Just bugfixing, performance and UI, and whatever needs to be done to finish this.

I have added this to the wish list but can't say if/when it might happen.

OK this is governed by a Windows option: Settings->Ease Of Access->Keyboard->Underline access keys when available.

Which I'd like to have it stay enabled.


Status of this option can be queried via registry.

[HKEY_CURRENT_USER\Control Panel\Accessibility\Keyboard Preference]
"On"="1" (if option is enabled, else it's "0")

Oh that's fine I don't care about the extra harmonics...I just meant the shape you currently have is slightly bent so it would be nice to just have a perfect curve (or whatever you would call it) to draw in Sine shapes

What do you mean by "slightly bent"? A triangle shape can turned into a sine that isn't bent at all.

Aha. Was about to ask Claude about it today. But the EvilDragon AI works just as well. :)

Yes, intentional. The MIDI learn overlay is static and wouldn't scroll with the rest of the UI.

Upsie. :)

Just wanted to head up and ask if the gremlins could have been removed for the Linux version. I would love to test it too :)

Someone fed the gremlins after midnight. We hope to get a Linux build on Monday.

Im really amazed about the quality of sounds coming out of this new beauty, Zebra 2 has always been my favorite synth, this Zebra 3 is incredible. The MPE works like a dream on Push 3 so do the new midi mapping possibility for the ctrl ABCD with Push and Live, fantastic work and worth the waiting time and thanks for the hard work creating this.
