I suggest improving the tuner on the Quad Cortex. It’s slow and sluggish! This obviously makes it less useful in live situations! I think this is something that can be largely solved with some new updates 
I have the latest firmware…
Interesting, I actually find the tuner to be very fast. I remember an older update had made it lag a little, but they seemed to fix that. Unless the newest update has changed that to have the lag again?
Ohh yes the tuner is slow… and it have lag! 
For me (and others I have asked recently), the tuner is locked on, doesn’t drift and seems to be as accurate as my Peterson tuner.
Locked on? What do you mean? I noticed that even if I play a string and tuning it 2 seconds later it is out of tune or in any case different from how it was before… it is not very fluid… this makes it very uncomfortable during a live!
Are you saying that the tuning of the string drops lower after the string rings for a couple seconds? Because that’s a more so an issue with the guitar itself
Can you verify it’s only set to one input? My bandmate had trouble when it was inadvertently set to an input pair.
Also helps to pluck repeatedly instead of just letting one note ring out
Obviously I know my guitar well and I did the test at the same time with a clip tuner and with the tuner of my kemper… the one of the Quad cortex has very annoying lags…
Thank you for your answer… the Quad cortex is set only with an input (input 1) and of course I repeatedly play the string while i’m tuning…
Just saying if it’s dipping in tuning as the string rings out, that wouldn’t be a tuner issue
Unfortunately it’s a problem with the Quad cortex tuner… with the kemper or my clip tuner I don’t have this problem…
Show us a video of what you’re talking about, seems like nobody else is having tuner issues on the QC.
I would love to see an update to the tuner. I currently run a Peterson tuner next to the QC because I don’t like the onboard one. I am sure they could easily improve the tuner, maybe add a strobe function.
The issue is that the QC tuner shows the pitch dropping flat as the string rings out? The headstock tuners usually don’t display that unfortunately, since they’re not as sensitive. I’m saying that having used much more accurate tuners such as Peterson and Kemper rack, which do show that pitch dip.
Unless you’re experience a delay with the tuner registering the note. Just a little confused on the exact issue
I mean that when I use the tuner, it locks on to the note very quickly and doesn’t drift. I used to have to pluck the string continuously in order for the tuner to lock on to the note, even then it was always accurate and drifted just every now and then. Currently, I have successfully tuned hitting the string once or twice when tuning and it matches my Peterson strobe. I do agree with having a strobe feature which is what you requested initially as I do see the value and prefer the strobe style tuner. I would also like to see support for Buzz Feiten offset tunings as well as others.
Seems to work totally fine with my trash guitars..and my trash playing. I have a strobe tuner as well and shows the same readings almost immediately.
I have to agree a little bit here. My polytune 3 it’s very fast and extremely stable. The QC tuner is slow and take it’s time to wonder around before it settles. It does seem to be pretty correct though, once it’s decided to stop.
Interesting. I can’t stand the Polytune. It’s so slow to react to the note and always jumped weirdly when it thinks you’re playing all the strings, so the note just flashes on the screen
I tested the QC tuner with the Kemper (which is an extremely fast one) and they read at the same speed/accuracy…..
Oh… I don’t feel that at all. It’s really fast, very stable, don’t move around at all and it holds the tone until it’s totally ringed out. The QC on the other hand takes it’s time to settle and dies quicker. I think it was the d or g string I have to hit pretty hard to even get it to read anything at all…
