Any of the above will probably work to play gigapiano 2 live, depending on what else is going on. I know I can do it with samples on the internal drive while using either Tascam usb122 or fw1884 audio interfaces. But I'm thinking of adding an external hard drive myself for increased capacity. Something like this:
Going external sata has the advantage of the highest performance and avoids conflicting with usb or fw audio interfaces. Just make sure where the power comes from... laptops don't provide a hard drive power connector: you'd need either a battery, an external wall wart, or perhaps a usb cable to deliver power to the sata enclosure.
Thanks for your response. I checked out bixnet and their site looks good.
I think SATA looks like a good bet. Wasn't sure because I got some contradictory info (from HP support, of all places) Otherwise I like my Pavilion.
I've been able to run GigaPiano OK but have experienced plenty of pops and clicks (and the occasional BSOD, but that was before 3.03). I decided to go ahead and invest in the separate sample drive, as recommended, along with another gig of RAM.
I also run Sonar 3. My MIDI/sound box is the m-audio Firewire Audiophile.
