as controller 14 uses the "fine mode", you don't neet to set controller 46. By setting contoller 14 to a value in the 0..16383 range, midish will set the lower bits in controller 46 as well. In your example you need:

oaddev {ctl fbq 14 33*128+96}

this will generate the two controller messages atomically.
