Yup it's the square wave alright . You answered your own question.

Sine waves are too pure to use for this sound.
The secret here is striking the right balance between the filter cut off and the ADR Amp envelope. Cut off is pretty low, the ADR is quick.
Don't worry about it.
We had a few discussions on this website about the source of that flute sound, we kinda concluded that is was an Eminent sound, as the Mellotrone flute is way too acoustic in timbre. This O2 flute however is more static, yet not too static. It has considerable reverb on it too. And some EQ for the lower keys, starting from about A4 down, to keep the fundamentals from being overbearing.
It's a pretty simple sound to recreate (using a harmonic additive synthesizer) (or a 3/4 oscillator subtractive), you need 3 or 4 harmonics for it. Adjusted correctly in amplitude. Then passed through the Solina chorus effect.
That gives it that spacey feel and some thickness.
Finally reverb and then Jarre styled hard panned delay.
I've done a couple of presets for myself and they sound just right.
You can use additive, subtractive or FM. Give it a try

Thank you very much Analog-Umph for your infos and suggestions.
Yes, I corrected the solo with the ARP2600 Square soundsource, and it's much better now.

I found that I was using the wrong filter this time and so the square sounded wrong. That's why I turned to a sine one.
Now I know what's the best Omnisphere filter for emulate the 4012 filter sound of the older ARP synths.
About the other sound: I would never guessed myself alone it could have been an Eminent sound.
But you all were right in your analysis.
Now I'm trying to reproduce it with the Eminent sampled library now.
Actually not having a real Solina, I don't have its chorus, so I don't know what to use for getting closer to that sound.
Do you have a real ARP Solina? Or you used an emulation?
Reverb before the panned clean source>delay Jarre's trick?
You mean in serial routing?
I read this also in some other thread, and I was going to ask...
normally people would put reverb as a parallel send of the clean source
or as a follow up to delays and other FXs.
When I've finished to modify my cover-replica sounds and fill the missing parts I'll upload an updated version on Soundcloud (For now there is the previous one).
cheers
