Hello: My system for reference: Apple Power Book G4 running at 1.25GHz with OSX 10.3.9 and 1.50GB of RAM, external HD, Logic Pro 6 and Spectrasonics Atmosphere. I need to know if someone has a similar system to mine (not so new, i.e. 1.25GHz processor) and having the NI's Akoustik Piano. As this is a plug-in and not a sample library for the EXS, I would like to know if it's running well and loose in the system, or if you had experienced some trouble with the timing and streaming of the plug-in at the time of playing it. I'm in the decision of buying it or not, and would like some advise from people with similar systems, or knowing others having a similar system. Thank you very much in advance for all your comments.
