Whatever method you use, some waveforms will be impossible to reproduce accurately in Geomorph - and that is a limitation.3ee wrote:Not really a limitation once you look at an oscilloscope rather than Zebra's wave editor.It seems fairly obvious that within the limitations of Geomorph you're not going to be able to precisely copy a given waveform (reproducing curves accurately is the problem).
Playing an "infinite" tone (output level muted of course) and than shaping in Zebra with the mouse sensitivity set to almost minimum.

So, will Zebra actually get an accurate waveform drawing mode? You know, like the one we have in the free Fuzzpilz Oatmeal? 
This also goes for additive harmonics mode where the maximum amplitude of n-th harmonic is NOT 1/n, but 1 instead (HarmoBlend)?

To get the wave nice and sharp.

Hmm, this is strange.
It seems that the popular Minimoog VCO emulations have fixed phases and they are phase aligned in a certain way ...with a long "subtle" phase/pitch modulation.
Is is possible to get some sort of phase controlled VCOs (not DCOs) in the real world and... does it apply to the real Minimoog?

Yeah, that's what I thought/think.Bronto Scorpio wrote:The oscs of the Minimoog are definitely freerunning
But that doesn't seem so with the emulations. I can't believe it!
Sorry, but if I had a real Minimoog I probably won't asking these "stupid" questions.

There are obviously only two "best" of them atm!hakey wrote:Which Minimoog emus are you talking about?3ee wrote:It seems that the popular Minimoog VCO emulations have fixed phases and they are phase aligned in a certain way ...with a long "subtle" phase/pitch modulation.
Btw. One of them is a couple of years old version so it may be possible that it got changed (don't know as I didn't found any change log)
but.. The other one.. I've got the demo 2-3 days ago and it seems to have the same issue. (Only a faster phase/pitch modulation.)
It may also be possible that a phase restart switch is hidden somewhere within the plugins themselves... dunno... I'm still looking for them
Anyway... I guess it's best to just post the friggin patch already...

If you find something wrong with it, please let me know so I can fix it.
Please feel free to write about alternative ways or techniques on "analog" emulations.
For example an alternative (cheaper) way to get a decent voltage gate bump is by modulating the osc pitch from lowest to normal with a fast MSEG for example.
Use the XY4 for the Noise volume and color.
Try a single OSC and check out the waves!
OSC3 was the inverted saw instead of the saw-triangle which sounds a bit different...
You can use that with a detuned, saw wave for PWM.
I think it turned out pretty good, what do you think?

Enjoy!
"Remember, for wall shaking sounds...turn resonance to 0!"

PS The audio feedback loop hasn't been modeled.

I like it!
I haven't played a real one, so I really don't have anything to compare it to, but it is nice to have as a basic template for building minimoog-type sounds.
Thanks for sharing

I didn't play a real one either.
You can try to listen to a triangle for example:
...and just for fun, compare it by ear with the one within the patch.
If you are gonna use the patch, take a bit of time to understand the signal flow and disable what modules you don't need, as this will save you CPU!

I listen to a lot of mp3 examples of classic analogue synths.
Check out a lot of samples of analogue synths.
Then try to capture some essence (however small) of the real thing, simply by ear, and not any technical ideas or oscilloscopes.
I also don't initially set out to create an emulation.
I just hear a resemblance come through as I fiddle with something, then work to make it better, after I realize it sounds like a mini or oscar or guitar...etc.

Yep - although I *can* get obsessive about technicalities too (like 3ee), in the context of this thread you must admit mcnoone made a good point there!mcnoone wrote:I listen to a lot of mp3 examples of classic analogue synths.
