Hmm very bizarre!- Could it have something to do with Yamaha's Middle C being 
different to other manufacturer's middle C's?- How out of tune is the korg? 
is it semitones of microtonal?- I know the AN can sometimes be a pig to tune 
to other things. It may be that one of your controllers is set to output a 
control while a receiving parameter on the Korg is assigned to that midi 
input which is corresponding to pitch- try turning off all controller outs on 
the AN and seeing what that does. (I had to do this once as I also had a 
similar problem- I think that when Yamaha set up the factory sounds, they 
also program in a whole load of midi assignments too- This can be initially 
confusing.

good luck!

This is a very good point. Double check you haven't inadvertantly 
assigned PB or a VCO1 or VCO2 Pitch adjustment to an Assign 
Knob, Pedal or Wheel that you hadn't intended too (see p. 9 of 
the Data List for Control Change numbers.)

 I would first check the Ctrl Device and Ctrl No. settings under 
UTILITY/SETUP - assuming the problem is global, i.e., it doesn't 
matter which Voice is active on the AN1x for the Korg to 
misbehave. If the problem occurs with only specific Voices then 
troubleshoot from the Ctrl Matrix settings.

What makes this rather bizarre is that its not a pitch bend but a 
semitone out on only certain keys. C and D are in tune over the whole 
6 octaves while E,F,G A and B are not. All the black keys are in 
tune. Its global as in it does not matter which voice I start up with 
on the AN1x. I guess this rules out the controllers output otherwise 
it would be over the whole keyboard, or would it? Can you please 
advise how to turn off all controller outs and I will try this.

Further clue. With everything switched on and the Korg still out of 
tune, I disconnect the midi in cable coming from the AN and hey 
presto the Korg is back in tune. So this means it is definately a 
signal from the AN that is causing the detune. Any ideas?

Sorry, could you explain this in a bit more detail for me and what is 
this Data List you mention?

Have checked the Ctrl Device and Ctrl No settings as described. There 
are lots of them. What am I looking for?

Thanks

Hi Alan,

It's a kind of an interesting problem you have there!

>>

not.

The only thing that I can imagine to cause this are either:

A) Some form of microtuning setup on the Korg.

B) Some form of Key Aftertouch setting being sent to the Korg which is
configured to cause a pitch shift.

Neither of these is likely to be transmitted from the AN1x.

That's interesting. I really doubt the An1x is sending any form of
controller message on a permanent basis that is holding the Korg in the
detune state. Much more likely is that the AN1x is sending active sense
messages (most Yamaha keyboards do. It's a message that tells attached
equipment that the keyboard is still alive). If this is the case, then
unplugging the MIDI IN cable from the Korg will stop the Active sense
message from arriving. Most equipments response to the loss of active
sense is to stop sounding all voices and to reset all controllers!

Hence the clue in this operation is that the detune is almost certainly
caused by a controller setup on the Korg. However it does not
necessarily follow that the AN1x sent that controller. Simply that
disconnecting the An1x forces the Korg to reset it.

Have you tried different combinations of turning on the Korg and the
An1x to see if all produce the same effect. Have you checked using
different patches on the Korg or even performing a factory reset etc. 

Sorry I can't be of more help....but I'm interested to know the cause
when you find it. Please make sure you post the solution to the group
;-)
