Hey all. I really need some help with this issue. I am currently recording a song on my Fostex MR-8 and I started to lay down the keyboard line by using a cable running from the WK3000 Line out/Sustain Pedal jack to my MR-8 line in.

All I get is a pop everytime I press a key, no actual keyboard. It's vital I can record with the WK3000 using it's line out. I checked my MR-8 Line In and it works perfectly with my guitar. ANY help, or anywhere that you can direct me for help I would appreciate VERY much. Thank you all!
