Does anyone own this drum machine? if you do hopefully you can help me.

I want to have a different tempo on one pattern than the tempo on another pattern. So on pattern 1 i want a tempo of 100 but on pattern 2 i want a tempo of 150. when i go to change pattern 2's tempo to 150 it changes pattern 1s tempo as well. is there any way of changing the tempo on different patterns?

any help is appreciated, thanks.
