Great App but needs instruments

It would be nice to have a separate general area for band instruments. With the various amount of keyboard options, I thought I would find at least one simple marimba/xylophone/vibraphone sound but there was none. I saw the section on keyboards that had a brass ensemble effect but I was looking for a trombone by itself. I like how they use the keyboard to make effects for different instruments and not cluttering the app but think more concert band keyboard effects would be nice. And maybe concert percussion too... Also if there is a sound that I was looking for I still would like to argue to make the instruments more locatable .
