I typically use Phil Flood’s STAX kits - especially V1 - great piano sound and full punchy bass but when I do non-BB work in the studio its Session Horns. Phil has commented on his libraries in the past. Of course in cases such as Session Horns multiple combinations of individual horns are possible - far more than BB could handle. BB would need captured combinations.
Its tough after I’ve spoiled my ears in the studio when I try to transfer the key parts via Reaper so we can do a song live. I might try to substitute Santana Piano & Organ (another favorite of mine from Phil) or some other.
As a reformed horn player the sounds so far in BB are limiting. Staying low in the mix adds some grit that works on some songs (e.g., Into the Mystic, She Caught the Katy) but not much more. Keeping within the limits of BB are there any new kits to incorporate that sound more like real sax/brass sections? It seems the handful of channels might be enough but maybe the limitation is availability of .wav files?
