When you select noise in the Bit Invader the wave is also refreshed/seeded again. If you select noise again the noise is refreshed once more while keeping focus but this doesn't work for automation. If you're working with a shorter wavelength it would be interesting to be able to refresh the wave with an LFO, equivalent to stepping through the waves of a wavetable synth.
I imagine it would be useful to add a separate refresh button to accomplish this or to simply fix this for the present button so it responds the same way when being pressed by an LFO as it does for a mouse click.
