I am using my compact flash and pcmcia adapter I use in the G70 and all the styles play fine. I'm even playing the extra styles that come in the internal memory in the G70 since version 2. The owners manual says that the E50/60 are using sounds from the highly aclaimed Fantom X series of keyboards. This is the same as the G70. The Piano in the E50 is called "Natural Grand" and the piano in the G70 is called "Grand X Piano" (or something like this). Slightly different I suspect, although it was very hard for my ear to hear because the G70 was played through external speakers and the E50 was both through it's internal, using the digital bass enhancer and external. I will check more today.
