When I open up the EQ for a track, say a bass part, and boost a frequency range, then go to play the track, the frequency boost disappears onscreen instantly. Why? What gives? I also noticed that sometimes if I boost or cut on a track, and then view the EQ of a different track in the same project, and then view the original track's EQ, the changes I made to boost/cut are gone. Beyond this, how do you adjust a frequency range precisely in GB? If say I want to boost mids / upper mids (800Hz - 3kHz), is there a way to plug these numbers in for the boost range? Cause when I move the dot in the EQ, I just move the dot over to 1500kHZ and then move it up a little, but the little hill that forms in the EQ spans far wider than 800-3k. Maybe this doesn't really matter anyway, since EQ is both art and science.

Hi InFocus - I can't duplicate the disappearing EQ setting issue here -- try the usual tests (shutdown/restart, test in other Projects, etc).. Re adjusting EQ numerically, you may have noticed that when you hover over an EQ node [the dot] it shows you the settings for that band [Frequency, Gain, Q [bandwidth]] in the lower right of the EQ display; if you select that node [click on it] then you can go down to the numerical readouts and type in the precise values you want. To adjust the range [which is called bandwidth] for that band [the width of the "hill"], you'd tweak the "Q" setting to taste.

Thanks. So the Q is basically the range and the higher the Q, the wider the range of the eq boost or cut?

Yes, Q is the range, but actually higher Q values correspond to narrower bandwidths -- by way of reference, a Q of 1.4 indicates a bandwidth of 1 octave.
