I often define a range and then insert a series of controllers or pitch bend events. This can seriously bog down the CPU because Sonar inserts too many events (e.g., 8-12 pitch events per tick at 120ppqn). One 1/8 note bend can have 720 events, and if I am doing 3-4 tracks of steel guitar, that is 2,880 pitch events on one 1/8 note. I have to use the Thin Controller or Thin Wheel CAL command.
For me, a simple way to change the default number of events inserted per tick or per quarter would solve the problem. If this were in Preferences or in an INI file, that would be great.
