[Solved] Using my MIDI controller how do I stop Cakewalk from playing two VSTs at the same time?

[kday]

When I play one VST in Cakewalk using my MIDI controller keyboard, the other VST plays also. How can I trigger just one VST module at a time?  It used to play only one VST when it was selected, but now when I leave that VST track to go to another, the old VST track still plays when playing from my Midi keyboard controller.  Is there a switch that I un-selected?

It used play only one track at a time, and when I left that track the old track was silenced and only the new VST track played, but now every new VST midi track selected keeps on playing at same time? So now every track plays the same midi notes. How can I play one track at a time?

Thanks for any help
