Yamaha A5000/A4000/A3000 Samplers From the Yamaha A series User Guide
"Ease and elegance are the first two words that come to mind when working with and getting to know the A4000/A5000. The A-series is truly as at home with traditional musical instrument “multisamples” as it is in the world of techno/hip-hop and dance “loops” – break beats. The capability to expand the on-board RAM to 128 MegaBytes with on board effect processing at this price point is a breakthrough (MSRP is $1595/$2295). This is a very big deal for those that understand, in sampling or computing - you can never have enough RAM or processing power. And the capability of burning your own music to CD or creating your our own CDROM Libraries makes these samplers very creative (and profitable) tools." This group seeks to provide information, experience and advice for the Axk line.
