Thank you. Melodyne has been helping me get somewhat 'forensic' in my working with audio samples for over 20 years now - it's the real "detective" here, lol.
Just discovered that with Syz Dim Violins 1 & 2, I can get them sounding phasey in unison if I have Humanize switched on in one of them but off in the other. When Humanize in both is switched off or on, there's no phasing! I'm pretty sure VSL has been very crafty as well as very pragmatic, and my hat is off to them for that. I can think of certain tricks that might be in use but since I've no wish to risk giving aid to VSL's rivals, I'll keep shtum.
Oh yes I know what you mean about auto-suggestion in this line of work - sometimes it's like having a built-in comedian who gives me a good laugh at myself; other times it's good anti-gaslighting practice for dealing with pesky narcs, lolol.
The case of Syz Appassionata Violins 1 & 2 seems to use different crafty tactics: mostly borrowing a sample from an adjacent pitch - see attached Melodyne screenshot (same arrangement as with Dim Strings testing above, but here with a few more notes in the chromatic scale).
I've never looked into this Violins 1 & 2 situation before and I'm grateful to you for having pointed it out. On the one hand, VSL have used their crafty tactics so well that I've never had cause to investigate it (and have unknowingly benefited from the price and storage advantages which come from these crafty tricks). But on the other hand, now that I'm aware, I'm prepared to find ways of going the extra mile in pursuit of even better realism whenever I feel a need for it.
Good to know you're still here and interested and bringing to bear your well-seasoned expertise, Plowman!
