I bought Omni yesterday but am still open to checking out Zebra again....I spent some time with it a couple of years ago & wasn't a big fan of many of the patches.Kaboom75 wrote:Zebra is the most versatile. Omnisphere is great if you want ready made presets and less options than zebra.
Something to bear in mind is that playing a wind controller isn't at all like playing keyboard....lots of sounds just don't work on wind controller, especially with how breath control needs to be configured. Omni seems to offer me a bunch of great sounds "out of the box" with very little tweaking needed to get them working well with breath control.
Kontakt has also been a staple of mine for a few years, especially with the relative ease of configuring breath control. I've found some great lead libraries over the past week and will probably invest in some of those too.
