My PC is a WinXP SP3 P4 2.8 GHz with 1 GB RAM and it's having big trouble playing the demo songs. May I ask what specs are required to play the demo songs smoothly and still be able to operate the Maschine software without the CPU going sky high? Not Maschine related, but hopefully someone here can help me solve this: My USB 2.0 PCI card by Conceptronic is causing the soundcard (E-mu 0404 PCI) to crackle. When I disable it, the crackling is gone. But I need it to connect the Maschine controller. Does anyone know a solution to this problem?
