Would be nice to have a way to invert a signal in Mod maths (specially MSEGs)

I'm trying to use an MSEG to control both volume and pitch, but the pitch has to start from where the pitch knob is already set, and pitch down. Only way to do this properly is invert the MSEG shape and set a negative mod value.

Essentially losing a MSEG. Mod math with "invert" would get rid of this issue!

All modulations can be positive or negative, in the Matrix as well as in the direct mods. So you can modulate pitch up and volume down...?

Check out the Rectify options in the Mod Matrix. You can invert there (per target)

I wonder if people complaining about the presets use modulation or context at all. Modulate with aftertouch or Modwheel at least, have a beat running in the background to give it a frame. Apart from that, just wait for the presetpacks that will come in future, no doubt there will be lots from great creators even suiting your specific styles. Urs and the other good people at U-He will survive if you don't buy this synth. For now.

Afaik it was just one guy and it's best to ignore him imo.

I'd like to add that I don't want to discredit critical voices, any feedback can be valuable feedback (wether it bugs me or not). If someone doesn't like something, they're not automatically wrong, nor right. It can be the start of a conversation.
But examples and concrete ideas are great, and we got these after a few posts, so all good from my side (I'm the factory library "compiler").

Thanks just checked, I don't think you can flip the signal completely (make positive negative and vice versa)

It should be added there though! Totally flip the signal

You were asking about an MSEG... it works for the use case you mentioned.

But yes, an "Invert" option would be a useful addition.

It doesn't unless you can explain to me how. You need the entire MSEG to be inverted (start from the bottom and then go up) and then have the modulation negative.

This is the only way to start from the current pitch and have it go DOWN from there.

Urs, as a "beta tester" I wish it was easier to make things start clicky. I noticed the Attack on the envelopes have a .10ms limit. They should be able to go down to 0. For instance, I'm trying to replicate the CR-78 cymbal and it's impossible without a click at the start on the white noise.

From the user guide:

Faster attacks
Although setting the attack to zero can still create clicks, especially with pure tones, it is not
extremely fast by default. For maximum click, set V1 to init and turn the knob up to maximum.

Keep in mind, once released, the factory library will move out of that beta folder, and favourite markings are lost. ....
Many thanks for the reply Viktor, and the heads up. I'll keep that in mind and get right on it in the morning. At the moment I have 265 highlighted as favourites so going through them all again would be fun, but also a bit painful! :hihi:

Been late to the party and only demo'd Zebra 3 today. It sounds phenomenal and has massive potential. But I personally find the UX highly unsatisfactory.

Is there still time left for UI/UX suggestions?

Congratulations, I think this is the synth I'm going to be using as my main workhorse for the next decade once it's done! The OSCs and Filters sound fantastic. I just have a few thoughts and ideas..

OSCs:

There needs to be an easier way how to add basic/ saved waveforms after you have deleted them from the top view, having to manually draw a sine wave in after it's deleted is a pain in the ass lol.

For context overview whilst making some Dubstep/ Neuro/ Cinematic wobble basses, it would be nice if there was a function where you could set a level of randomisation between the curve morph so that by modulating an LFO or MSEG between the windows you get a bit more unpredictability. Note in Serum I understand that wavetables are setup in such a way where this quite easy however it can sound thin, overly digital and metallic so I assume this would be a similar result with if each window had that. Just something that makes it easier to set up rather than programming 16 different windows and using the morph function in each one. You already have your cleanup, beauty and simply functions so hopefully with these algorithms, it would mitigate some of the 'thiness' of some of these user friendly sounds to make in other soft synths.

Phase Rotation I think needs to be a visible function. When I was trying to make the big CS-80 blade runner leads (or a more authentic recreation of Rufus Du Sol Innerbloom Lead) I kept running into phase issues even when stacking just two oscillators with high un-calibration like in your Youtube video. Given how warm the Osc and filters sound I feel something like this in the OSC editor needs to be addressed.

Detune knob need a logarithmic function the shift key is fine but with modulation it becomes a mess for programming.

I look forward to your import wavetable functionalities more and hope that these will be more detailed and fixed it the release.

User Guide:
The Posterize function I can't seem to set up correctly or not using the right modulation path in Zebra or Zebralette this needs much more detail or a tip note like you do in other sections.

Modal: I think it would be amazing if the modal had a self oscillating function built in. Something where I can use all the cool built in FX like creating synth based robot FX without hearing the sound of the OSC, FMO or Noise before it.

Distortion/ foldback are a little bit strange in terms of dialling the settings and the sound quality of these might need to be improved.

GUI: I'm sure lots will have suggestions on this but for me the most obvious fix needs to be a right click function on the right side below Envelope 1 to add LFOs MSEGs etc.

In the preset menu it would be great if there is the optionality to rename the favourites categories also make an easier way to add and remove tabs from the sidebar. For context I'd like to be able to make sounds on the fly with my laptop and have an easy way to import my own banks and presets to another computer. Have customisable categories by user (in my case myself) and sub categories eg. Category: Basses into set sub category folders 'FM Donks' 'Reese Bass' 'Neuro/ Complex' etc. It's quite annoying if I was to set a sound in a category that I would have other artist banks and sounds lumped in their as well.

While saving presets I want to be able to save it to a category, name a sub category, tag, features, character like you have in the tag section and a way to modify these tags to fit in the tag editor directory to organise all my sounds.

I know this is a lot and quite specific to my circumstances but I would love if you could implement some of these changes in the next revision.
