			==Little Bug Note==
			After running the OpenBCI Module with 16 channels and SampleBlockSize of 25, in the timing window, there's latency of around a minute after which it shows the expected output (or straight) line by default. This needs to be resolved.

	In case you are experiencing problems by higher sampling rates (e.g., data loss, jerky display, etc.), increase the SampleBlockSize so that you are updating the system less frequently (usually, updating the system 20-30 times per second is sufficient for most applications), and increase Visualize->VisualizeSourceDecimation. This parameter will decrease the number of samples per second that are actually drawn in the Source display.
