When you open the key editor in cubase there?s a lower window showing the velocity of the notes. If you go to the drop-down menu (that says "velocity") you can select a number of different other controlers. Some are allready named and this IS NOT the same in your Virus but behind the name is a controller value. You can choose these to control different parameters in your Virus (or any other MIDI-synth for that sake). Lets say you want to sweep filter 1 automaticly. Then you would choose the one called "Balance LSB" witch refers to controller 40 that is filter 1?s cutoff frequency in the Virus. Now you can "draw" the value (with a pen or a line) to make the desired sweep. The same goes for all the other controllers. You can actually make an intire patch from controller info and send it to the Virus and you will have the patch without having to save it in the Virus (but this is easier with SysEx). Now you may ask: "What the hell is SysEx". Well SysEx is a machine-code language that MIDI devices can use to "talk" with eachother. The benefit with SysEx is that it dosn?t "fill" as much as controller-data (controller-data is what we used in the filtersweep i just explained) and therefore is sent more rapidly witch makes it more suitable for sending larger amounts of data in one go. If you send large amounts of date as controller-info you may slow down he MIDI-transmission and the song may slow down or halt (witch you DO NOT want in the middle of your live setup). I hope this helped you and didn?t confuse you even more. Try reading some articles, webpages or books about MIDI. There?s tons of learning sites about MIDI on the internet.
