I own a Korg M1 Plus and the Trinity Plus which are both good boards. I know the systems in and out but I don't know why people are making such a big deal over the PBS-Tri option. You can't sample nor can you edit the samples unless you're running a pc along with your system. The bottom line is that if I'm gonna do anything kind of music that I'm going to have to sample or use a sample, I'd rather purchase an Akai MPC 2000, ASR-10 or another model. You can't go wrong.
