Everyone,
Thank you again fro your comments and suggestions.
I tested the combination save and load functions tonight and I cannot make anything fail.
Perhaps those of you who can only save the Positif combinations are using the wrong set of pistons on the console. The generals go from 1 to 12 while the division pistons only go from 1 to 6.
As for using a newer version of Piotr's sample set, the stop and coupler action improvements would make no difference as I have redefined all of this in my extension anyway. This is why I have so many more couplers, for example. I have impel,ented my own set of not fixes within the extension, so this also should not be necessary. I went through every pipe very carefully and patched any problems with level, releases, and tuning myself.
When I awn ready to do an update (to fix spelling, for example!) I will examine the latest version of Piotr's samples to see if there would be any difference.
