Piano roll Help needed please

After making the selection, enter the new channel number in the Event Inspector module.

You guys are great. Thanks for the sharp reply :)

Greetings and welcome to Music Creator.  
 
You stated, "My problem is that I want total control of everything." and "I want the same compositional control I had with Anvil but with the enhanced instrument quality I hear in Music Creator 7. Is this possible?"
 
We need additional information to try and help you.  What tasks do you want to do?  Is there a specific Anvil Studio feature you're looking for?

I use a very simple CAL program, mapped to a key shortcut.   
 
Copy this into notepad, save as "set_channel.cal" in your "Cal Scripts" folder under Sonar Platinum (or whatever sonar you use).   If you use it often, map to a keyboard shortcut in Preferences.
 
 
; set_channel.cal  Set Midi Channel for selected events.
;;

(do
    (include "need20.cal")    ; Require version 2.0 or higher of CAL

    (int new_chan 1)    ; New Midi Channel number
    (int i 0)        ; index for moving through

    (getInt new_chan "New Midi Channel: " 1 16 )
        (-= new_chan 1)

    (forEachEvent
        (do
                (= Event.Chan new_chan )                              
                (++ i) ; this counts
        )
    )
       
    (pause "Adjusted " i " channel events!" )
)

Yes, the script only affects whatever midi events are selected, so your selection can be as complicated as you like: select only certain tracks, note range, time range, controller, etc etc.
