Hi there,

does any of you know how others handle it?
I like ACT mode very well. how does this work with other DAWs?

I believe ACT is Cakewalk specific and does not work with other software, but all DAW's have their own type of hardware integration
 
To be honest, ACT has been a bit tired and neglected for quite some time. You will probably find some other DAW's have smoother hardware integration. This is particularly true with DAW producers who also make hardware, such as Presonus.
