Hello,
Could we PLEASE replicate this envelope modulation rusty flute whistle effect with regular oscillators:
(915) How to REALLY use your envelopes - All about envelopes - part2 - YouTube
Between 8:39 and 9:24 the roof of the barrel house tears off 
It doesn’t sound remotely like a pipe or flute to me. I imagine the wavetable makes a big difference. It also sounds like a lot of distortion coming from somewhere.
Well, I was reffering to an imaginary copper organ pipe from the movie Nothing But Trouble kind of thing 
. Also i think by holding a screwdriver or tool against a turning metal disk the “rusty noise will appear”. He is using the Erica Synth Black Wavetable VCO. Do you tink It is possible to do something similar without a wavetable?
Why not use the Erica Synths Black Wavetable VCO? It’s available in Rack:
You also could try to achieve something similar with FM or wavefolding maybe…
Yes! could you please elaborate how you tink about FM and wavefolding, my intention was to do it with the synths I have which is a behringer crave and a volca keys and then run them into vcv and control envelopes and modulation from VCV. The keys have ring mod where i can get the metallic sound on it, and the crave has an FM input. Also to do the filter in audio rate also creates metallic sounds on the Crave.I thought maybe an envelope that controles the rate of the lfo that modulates the filter?
I am not so experienced with FM.
So far my experience with FM is that I kind of think i need to sample it. Because there are mostly settings that is not usable because they are to “scratchy” and there is only some pitch settings that have a nice wavy balance in them, im not sure if im doing it correctly. Here is a screenshot with the ring modulator also

I’d recommend to do it in VCV Rack with the Black WaveTable VCO.
Options for FM with Crave and volca might be a bit limited… maybe you can patch the volca into the FM input on the crave? But it’s probably not loud enough for eurorack signal… never tried that 
I am planning to buy 3 eurorack oscillators and 3 filters from the behringer range or maybe doepfer tops, nothing fancy. So i will have more voices and filters at my disposal to do it. But not wavetable. I would like to learn how to do it with normal oscillators and maybe in extension wayveshapers, ring mods, wavefolders, the audiomanipulators so to speak learn how to build with the basic stuff.
I am not getting any barry white soft bells from the the FM in my screenshot, only very harsch drones to medium light harsch drones..
I also have 8 CV outs from my dc coupled audio interface so I can send 8 CV signals from VCV rack.
Well to achieve the overtones coming in and out you would want to modulate the FM with an envelope, using a VCA… If you want all those things in Hardware the Behringer Proton is a really good choice, since it gives you some envelopes and VCAs and LFOs and stuff…
In VCV Rack you would do it something like this:
simple enveloped FM.vcv (1.5 KB)
If you switch the FM on Oscillator 1 to linear it even stays in tune
Most inexpensive hardware oscillators only do exponential FM and then go out of tune, which makes it a bit more difficult to handle.
I would say your patch gave the exact same overtones 
. Also, two sines into a wavefolder gave some nice overtones. One two octaves below the other. I will keep working on the modulations now. I have problems with the random scource, it becomes to glitchy for my taste very fast. I want to have a “humming”-vibration like small movements in cutoff (or maybe amplitude is better?) then on top of that a bigger movement instability modultion. Is it better to use LFOs for these? Can I calculate modulation instead of listening somehow? 
Just try different things and experiment and have fun with it. It’s all about discovering what sounds good to you, so I’m afraid you have to do it while listening.

Here is the wavefolder patch. I cant figure out what is causing the brightest harmonics to peak so i can connect it to the modwheel, it is not turning the big knob on the wavefolder, because i did that all day at work today 
Nice! Can’t watch the video because it is set to private, though.
Dang, how about now?
yes, works!
