Reply to Ableton Master Tempo Adjust

Hello all. I realize that this is mainly a Traktor community , but I can't seem to get anyone to even reply to my question on any other community s, so I thought I would try here, as it seems this community is always willing to lend a helping hand.

I'm trying to figure out how to do something on my Launchpad using MidiKatapult, and so far no luck. I posted this question on the community s there, but not even on reply after several days.

I have been racking my brains trying to figure out how to do this, so any help anyone could give me would be greatly appreciated.

All I'm trying to do is set up 2 buttons on my Launchpad. I want one to decrease the master tempo in Ableton in 1 BPM increments, and another to increase the master tempo in 1 BPM increments. I've tried everything I can believe of, and I can't make it work. I'm hoping someone here has the expertise to help me with this.

Thanks in advance for any help that can be given.

Michael
