Bernie, Rikki & Scott, I have no trouble using SGM180 or SGM128 on my Music Computer. I have 2GB of memory. When it comes to music the more the better!!! From an Auto Accompaniment perspective both the SGM180 & SGM128 sound fairly good. As you know I plan on staying with Bandstand which is a much larger wavetable but it uses disk streaming to reduce the amount of memory required.
