Here’s a diagram of how I believe that the 1.03 structure works:
The pattern menu Reload from / Save to affect just one pattern. The Settings menu Load / Save affect all the patterns. All these operations afftect the Temp area, setting it the same as what is stored in +Drive.
Note that the Temp area, unlike the clipboard, has space for each pattern. You can save a pattern to the Temp area, go off and play with another pattern, save that to the Temp area, return to the first pattern, and reload what you stored at the start.
