I know.... It is a ridiculous built-in TUNER plugin, but it is annoying... My Korg DTR-2000 is in a rack in my live rig, and I just hate not having this little handy dandy tuner available on an insert. (metering>tuner). Seems as though it worked fine in Logic 9.0....hmmmmm This plugin simply does not respond...it loads without issue, there is a signal on the channel that it is inserted on, but does not respond. It does not work in standard mode, or precision mode. However, it looks pretty ....however it doesn't see the incoming signal from guitar or bass. FWIW, I generally have the channel record enabled by the time I get around to tuning.... I am sure it is something simple and stupid that I am overlooking, so lay it on me, and thank you all in advance!
