Treated myself with Rob Papens latest synth Blue II. Really nice sound, but a real resource hog. I've got a MBP with a 2GHz i7 (4 real cores + 4 HT), 16 GB RAM and an SSD. On some sounds the CPU meter in Cubase hit the roof with only like 8-10 voices, despite it being the only instrument loaded. It's only v1.0 so hopefully it will be fixed in later versions. /Micke
