Bc2000 (for the BCF2000 & BCR2000)

HI ALL.  this is my first post here.  I recently purchased a bcr2000 to control my mks 50 and i have no idea what im doing when it comes to sysex. could someone please explain how i go about seeting a knob on my bcr2000 to contro0l lets say the filter frequency for example.  I dont get how to set up the sysex info.  do i need some type of software to send sysex? cant i just just share that info between the bcr and the mks50 without any other software? im really confused on how to do this.  please be as specific as you can as im new to this.  Thank you all for any help you can give
