Thesis:
This isn't such trivial because the powerline and the clock modulator runs asynchronously. This is relevant because everything is interconnected. Further could exact timings cause power tops?
To adjust frequency you need execution stack and the ability to synchronize. This is further the prerequisite to do capacity hacks!
Conclusion for Advanced Gtk+ Sequencer would be to feed the net. And its reliability would suffer therefor. One more it could be used to do measurements.
