Hello.............I downloaded the mp3 samples and they sound very good. I have been using a similar program called the Roland Sound Canvas Pipe Organ Project (SCPOP)and have been very pleased with the results. The SCPOP requires a Roland sound module......at least an SC55. I have a SC88 and have no problem running the latest release. After downloading your samples I went back to download the program, but couldn't link up. I'll try again later. I'm curious how your program will sound thru a generic Yamaha XG soundcard. I'm also curious how it will sound thru the SC88. What soundcard did your samples come from? I have 2 keyboards and a homemade midi pedalboard. Your site recommends a midi merger.........can a midi thru box work as well? Thanks.
