My Grand Adventure pack has a couple South American flute based tracks. You can hear one of them here. There's a clip from another in the video trailer for the pack...
I don't think I have anything Middle Eastern in my packs, but I did compose quite a lot of that for my soundtrack to Renaissance Kingdom Wars, so I have instruments available for that style. Surprisingly, I have not done a whole lot of angelic choir music, but I have plenty of choir instruments to work with. If you are on Discord, friend-request joelsteudler or email me at joel @ joelsteudlermusic.com and perhaps we can work something out!
