There has not been a good Jazz orchestra VI, that I am aware of, in a good number of years. This is a demo from a project in the works. I am keeping my eye on it. I love this sound! I am betting I am not alone on this one.

Have you looked at the following:

There are others but this hopefully will help.

Good luck

I’m using SWAM instruments by audiomodeling, after a long search in which Mario helped.

Info on this Diamond Jazz Orchestra product was hard to find, except for ‘coming soon’. Sure, it will be fun to check it out when there is more info. Thanks.

I once had the garritan jazz and big band - but this goes back amost a decade or more and I lost it on a computer change. However, the new releases of the bigfish products, I totally missed. I really need to get out more. Thanks.

The idea behind Garritan was to keep CPU load low. For solo voices that meant low quality sampling, but a good ensemble sound, nevertheless. It’s dated…

Big Fish takes a different appraoch, now that processors and Ram have improved so much. Sounds impressive to my ears!

Nothing beats audiomodeling for solos, trumpets and saxophone, I think. With a keyboard or EWI, these can’t be beaten. Expensive stuff, though.

I’d love to own it all, but then my wallet says No!

I hear ya. I have the trumpet and saxes and they are the best sounding solo instruments. However you can stack them and make your own big band.

I'd like to have more also but my wallet is just like yours!

. . . and, here's a fur-lined rabbit hole:

There's more but I have to stop. My brain is starting to hurt.
