Fine I and Fine II - The sliders have a selection of ranges, namely, 1.0kHz, 2.5kHz, 5kHz, 10kHz, 25kHz, 50kHz, 100kHz and 200kHz. There are Fine and Hot controls at the right hand end of these sliders. Clicking on these controls provides a quick and easy method of changing the tuning range and mouse wheel step settings without going through the Program Options menu.The Fine I slider is visible all the time. The Fine II slider can be disabled via the Show Fine II selection from the menu but it is handy to have as it can be given a different tuning rate to Fine I.
