in case anybody skipped over the previous post because of its length...
it's a step-by step tutorial on how to use Continuous Controllers in Real Band to totally control a vocal processor (turning things off and on and changing parameters)
programmatically wherever you want the cahnges to take place in the song.

The same principles also work for other MIDIable devices, such as synths, many guitar effects, etc. Since most people on this forum are using sequncers to make music, and are often playing live with the sequenced songs, this information is VERY useful and empowering.
