Hi, I was looking into the Emagic MT4 USB midi interface for PT LE then thought perhaps it might be best to get a Digi 001 with it's built in midi port. The PowerMac here is a G4 466Mhz, 133bus speed, 256Megs, OS 9.1 and my concern is for latency and midi slop. Emagic says they have cleared the USB hurdle, and it has 2 in/4 outs. The 001 has single I/O via the PCI card. I only need the one that works right. Thanks.
