Groove Agent 4...Only able to hear in the right channel

Hi All,

I am facing with a very tricky issue with Groove Agent. Only right channel is audible, very less sound comes out of left channel. It does not happen with any other instrument. For example I tried halion 5 drum kit it works fine for both the channels.

Can you please help me?

My configuration: windows 7 pro, cubase 8.5 pro, absolute 2

Thanks and Regards
