Latency is a bitch. If you want anything to run on real time with zero latency, then it means everything, including those pretty large sample data, has to be stored as close to the processor as possible. Compressing/decompressing takes a shit tonne of time and effort, and to keep both delay down and fidelity up, you have to pay in absurd amounts of RAM to the DAW shrine.
