GLM is a weapon that goes beyond many necessary benefits. It is a voice-bending program that changes the entire behavior of the voice structure more than many of you can really properly understand how many sound images or changes in sound rhythm are available. Yes, there are millions of changes available from the GLM settings, but many people are not able to separate them from each other very effectively using their hearing.
It is as if you were looking at a slow-motion swarm of mosquitoes near your face and could distinguish each individual to your advantage. Of course, following the behavior of the swarm, different shape variations often emerge. Everyone notices that in mosquitoes or birds or fish, because everyone sums up the perception of reality with the processing of your brain. But if your eyes or ears become trained over time, the perception of reality will emerge over time, better processed. The sound image and the tempo and rhythmic nature are better and of course easier to modify than if you are a novice music listener or a half-deaf person, or a man/woman too old to learn anything new and wonderful.
