I have used the Zoom H2 with my Tyros 4 several times and used the line in from my T4 headphone output and it worked great. The Korg KMA headphone output level is a lot hotter than the T4's and it seems to overwhelm the H2 and all I get is horribly distorted recordings. I am experimenting with various recording levels on the H2 and will post my findings when I finally get a solution. I think others here also use the H2.

The Korg KMA has a lot more power output than does my T4. I run my Bose speakers a lot lower for the same sound output when using the KMA.

John, no offense taken.
Donny, got your email - thanks.
