Re: Best way to use Digital Performer (MAC) and giga.
You basically need to buy a PC and turn it onto a sampler. It would then operate much like using any hardware sampler with Digital Peformer and a Mac.
The PC needs a quality sound card (preferably one with Lightpipe outputs that could connect to MOTU hardware digitally) as well as Midi inputs and outputs. There are options from RME Hammerfall that are excellent.
There is also pretty good documentation on the Tascam Giga Website.
