I currently own a Korg SP-500 digital piano. I should have purchased the Korg Triton Studio 88 but did not have that much cash at the time. The Sp-500 has around 400 digital sample but some of them are pretty cheezy and will not cut through the sound of other instruments when played live. The organ samples in the SP500 are very weak. I wish to purchase a sound module/synth and am looking for some recommendations. I have an IBM Thinkpad PIII/700 laptop and I know there are a great number of software synths available. Should I look at the software option? The Korg Triton Studio sound module looks good but pricey. The Yamaha Motif sound generator looks good too and is priced better. I just need something with a variety of good quality sounds primarily organ(Hammond B3/B4would be nice), pianos, strings and brass. I need to be able to program the instument changes to presets on my keyboard so I can trigger the changes during live performances. I play in a band. We do mainly 70's rock and blues. Any advice would be greatly appreciated. Regards, Bruce Holm
