you're both right, but Rikki is a little righter

Willum, you're right that a pad in a sequence is an event that requires either the correct preset pad to be present, or the correct user pad to be loaded.
Rikki is also right that the pad has two tracks available for rendering in apc to smf convert, so any pad can be simply easy recorded and then sent to two sequencer tracks where all the individual notes are there available for midi output. I was once asked to make technics pads for yamaha owners by this route in the days of the KN6000, and the principle is used in the practical editing exercises in the 6k book, including using the sequencer to make 3 (or more) track pads etc.
