Ways to change midi channel on Freedrum using Sensorware App


Is there a option for the Freedrums to have the capability to change midi channel like in those keyboard midi controller to control one app with the same midi channel. I want to play the freedrum with a friend who has a midi keyboard. The midi keyboard triggers a piano app and I can trigger a drums app . If you already can change the midi channel let me know as I want to use two midi device.Thanks
