The noise suppressor is intended to be used in Front of the signal chain to clean up input noise. Putting it on the back will work if you've overused gain and distortion settings and created noise BUT if you've used time oriented effects such as reverb and delay you will effectively cut off their tails muy pronto.

I don't have a midi pickup but I wouldn't think they are noisy. Are they noisy? If not then the noise comes from the amp and distortions you are building. Many presets have noise because they're overdone for the marketing guys. Learn to develop your own by starting from scratch and you'll be much further ahead in the art.
