Controllers
Controllers are the MIDI events such as volume, sustain pedal, and pan that you use to change the sound while you're playing. You can enter controller data from within SONAR, or record them from external devices such as MIDI keyboards.
Controllers let you control the detail and character of your music. Say you're playing a guitar sound on your synthesizer, but it sounds lifeless and dull. That's partly because a guitar player doesn't just play notes one after another--he often bends or slides on the strings to put emotion into his playing. You can use controllers in the same way, creating bends, volume swells, and other effects that make sounds more realistic and more fun to listen to.
Your computer can work the controllers on your electronic instrument by sending MIDI Controller messages. The MIDI specification allows for 128 different types of controllers, many of which are used for standard purposes. For example, controller 7 is normally used for volume events, and controller 10 is normally used for pan. Every controller can take on a value ranging from 0 to 127.
The Piano Roll toolbar contains several dropdown lists that let you choose the controller you want to see and edit. The contents of these lists depend on the output and channel settings and on the instrument assigned to that output and channel. Different instruments use controllers in different ways.
that can import 50k midi files...but the volume is way too low...and it is the same in Sonar too, even though each of the tracks shows a volume level of 127.
Anyone has better word ? Sorry, I'm a bit cold tonight...
