I assume you are talking about pads on a Arturia controller.
You should be able to use the Pads on a Arturia to send Bank and Program Change messages. The messages work for presets in Concerts. So you should be able to program a pad to select a certain preset in your concerts. You can also use buttons for this.
A Bank messages should select a specific Concert (number 0-127) and the specific Program change message (number 0-127) should select a specific preset in that concert.
I don't have a Arturia controller, so i can't test it for you. But in Arturias Midi Control Center i can see, that pads can be set to send those messages. Just select the Program Change option in the MODE drop down menu, and set the needed messages.
