Note
If the Delta you are modifying was created using memory modification (therefore having
both absolute and relative values), the relative values always relate to the value in the
source memory. Example: the Delta derives from memory 2. In memory 2 the original
value for channel 2 was Full. The delta was created when channel 2 was modified to 50%,
therefore the delta consists of an absolute value of 50 for channel 2 and a relative value of –
50. If you modify the delta, assigning 75% to channel two, the delta will contain an
absolute value of 75% and the relative value is updated to –25%.
