If I use a preset I like which is tuned to say G and press Keytrack and put the midi note on F is it now tuned to F as I type this question I would assume so but just making sure.
If you use a preset that is tuned to G - with keytrack on, then it will playback G when you are playing middle C.
For it to play F, you would play B - confusing? If you are going to use keytrack its probably best you tune it to the key you are pressing. i.e. play G on the keyboard and then tune it to G
