I'm also Cakewalk Sonar refugee, and really miss the abilty to set an outer loop, and an inner punch-in/punch-out "loop".
Even Harrison's Mix bus allows you to set the two independant of one another...
Maybe V4 has added that feature?
Can a Studio One user please chime in?
How does one set punch-in, and punch-out points, and also set a loop around them for looping back to hear pre-roll???
