You can use a program sequence, but only one (or two) fundamental frequencies run at the same time. For remote, we want the sequence to repeat within 4 hours - although 2 is better. We also tend to group like programs together, so if we want to work on several different issues at once, we use multiple remotes.
Another reason is that we typically do not modify any Presets that have programs already loaded in the software, so each of these that we want to run will be in one generator.
