Regarding scat voices - I wonder if you are aware of the "Jazz Singers" Performance already provided?

If you need to have more choices - there may be something. Requires more research. There's also the possibility of reconfiguring the underlying waveforms for your own custom Performance.

When doing a [CATEGORY SEARCH] - find all of the vocal Performances and see what's there. "Pad/Choir" main category, "Choir" sub-category.

My apologies. For some reason I haven't seen this patch! OK! Jazz Singers very beautiful patch!
I somehow earlier sampled omnisphere but manually i'm never happy with the result.

btw please advise me waveforms to mix the crystal glass sound like D-50 classical patch sounds.
Some bells, steel and oberhaim strings? Any ideas! Natural timbres are too recognizable it's not very good they need to be mixed somehow cool.

Is it "Fantasia" you're after? I see a Performance called "Fantasy" and another "FM Fantasy" under the main category "Chromatic Perc" and sub-category "Synth Bell". They are right next to each other in the Performance list (Data List document). I haven't listened to them so I don't know how close they are to "Fantasia" - but it's fairly typical that names inspired by other gear is thinly veiled. Still, about a 90% chance this sound doesn't match what you're after.

If you don't want to discover first what you already have inside your instrument (I would do this first) - there's a set of D50 presets sampled and assembled for the Montage or MODX. An internet search will lead you there. It's not distributed through official channels and I haven't looked into these sources. There's several different packs it seems. There's also a player who claims to sample his own stuff. Some packs are free and some are not. The D50 pack happens to be free. There's a lot of free choices seemingly as teasers for the more extensive packs.

So if you look around - there's a lot of choices for D50. I would tend to think without purchasing a pack - and without using samples - you can get pretty close with what's in the presets already.

Thank you, Jason!

MODX Fantasy is good!
I like sound GX1 and Sci-Fi although they are not fat enough

It’s not that I’m looking for the D-50, but it’s like landmarks where to go and approximate direction.
