John,
The line out shouldn't change with the volume adjustment--it should remain constant. The headphone out, at least with most keyboards, is directly effected by the main volume control. There is an input adjustment on the Zoom-H2 for both the mic and the Line-In.
Hi Gary,
I am afraid you are wrong there. I know that normally speaking a line out should not be aligned to the volume knobs etc. but believe you me it does with the Micro, and to the best of my knowledge it does so with most Korg keyboards. I just double-checked in my own set up where the Micro is coupled to a Yamaha PSR900 and like I said, also the Line Out of the Micro runs via the volume sliders.
In a way this is a bonus to Deane, cause as I mentioned earlier on this way he can trim the recording level to perfection in two ways.
regards,
John
