EastWest Hollywood Orchestra Opus Edition (Diamond)
The Diamond tier of EastWest's Hollywood Orchestra in the OPUS engine is a 944 GB film-scoring library covering strings, brass, woodwinds and percussion with up to six mic positions. It stands out as the most capable, no-compromise option in this group for composers chasing big-room cinematic sound. Skip it if you're short on roughly a terabyte of storage or only need a quick sketch palette; the depth here is the whole point.
