YES, Shows created on the Masterpiece 108 can be directly loaded into the Masterpiece 216 with the Scenes only containing levels for the first 108 channels. Masterpiece 216 stores 8 Shows in it's internal battery backed 512Kb memory. Each Show can be recalled instantly by simple key presses. The number of Shows you can fit in a memory card depends on it's size. A Show is 64kB therefore the 128kB card supplied with the Masterpiece 216 as standard holds 2 shows.
Larger cards are available.
The 256kB card holds 4 Shows and the 512kB can hold 8 Shows in total. It's perfectly possible to use four 128kB cards for example to store all 8 Shows from a Masterpiece 216. YES, you can. From any Show to any other Show internally and externally in full or in part. The combination of having 8 Shows and the intended functionality of the Chase Generator means that the real power of Masterpiece 216 has been greatly expanded.
