To measure the pitch I am using a single note and running it from my amp through my boss guitar tuner pedal. I have done the same with my Keyboard. My pitchbend wheel is centered. i have a Casio Px-3 I have written to casio to fix this because I have found that I can move the pitch down by -4 cents and it comes in tune, although only from C2 to C6 lower than the c2 and it’s getting flat, higher than the C6 and it’s getting sharp again. (Almost like a real piano) They have provided me with instructions on how to reset this and keep it (currently everytime I turn the keyboard on I have to shift it -4 cents).
As for the actual sounds, I don’t often use the Steinberg VST sounds I mainly use Komplete. I chose a plain sound to test this on, just a single piano note because some digital tunes using polyrhythms etc you couldn’t really get a reliable tuning off. I figure once I have sorted out whatever is causing the pitch issue is sorted all of the sounds will then be ‘in pitch’ -4 cents isn’t much but when all the guitars and bass are set to 440Hz and the keys are at 444Hz it just doesn’t quite sound right as you can imagine.
I will test whether shifting the Keyboard down and then plugging it into the midi changes the sound in the midi editor. If so I will post this as the fix and just have to go back over all the midi sections and re-add in a note with the keyboard midi at the right Hz.
If it hasn’t fixed the problem I’m not sure where to from there. Guess I’ll find out this weekend once I’ve road tested the above.
Thanks everyone for your replies
