First of all, Rolandfan is absolutely right. I tested the G70 and it is probably the worst sounding arranger in its class on the market. Secondly, the wave Rom size of 192MB is not the physical size. You will see �when expanded to 16bit linear� in small letters on all Roland brochures. The data is compressed and I assume the actual size of the ROM is 128 MB. Thirdly, you can fill 50 GB or more with useless poor sounding waves. The size does not say anything about the sound quality. That is like judging a book by the number of the pages.
