No, I meant like an "always on" meter, like on the Axe itself.
You can leave the tuner window on at the FC, but it is not a "mini-meter" that is always there like on the FX and FM unit windows, it takes up the whole FC screen. It is my understanding that there are actually two different tuners on the FX and FM units. One is a simulated strobe tuner (accessed by going to the tuner function) and the "mini-tuner" which is something other than a strobe tuner and I believe a simulation of this is the one that shows on the FC screen (strobe simulated tuner always looks like a strobe wheel AFIK and only shows on Axe screen). Here are some quotes from Cliff off of the Fractal forum regarding the tuners (but not the FC functionality):

The strobe tuner and bar tuner use different algorithms. The bar tuner measures the average period of the waveform. The strobe tuner works like, well, a strobe tuner. It "demodulates" the signal with a quadrature oscillator. This effectively measures the fundamental ONLY. The frequency of the fundamental will not necessarily match that of the overall waveform.
So it's like having two tuners, a traditional tuner and a strobe tuner running simultaneously and, just as with separate physical tuners, the results may not necessarily be the same.
A guitar string is not perfect. The resonances of the overtones aren't always perfect integer multiples of the fundamental. This is exacerbated by the pickups which pull on the strings and cause the overtones to be off (in extreme cases causing the dreaded "stratitis").
Which measurement is correct? That's up to you decide. Some people prefer the sound of the strings being tuned to the frequency of the overall waveform. Others prefer the results of a strobe tuner.

The needle is a correlation tuner. The strobe tuner downconverts the signal to baseband and then displays the I/Q vectors as a strobe tuner simulation. Zero-crossing tuners are inaccurate.
If your strings are old the needle tuner will differ from the strobe tuner because the strobe tuner only displays the fundamental. When your strings get old the harmonics become out-of-tune with the fundamental.
