unwanted noise

[Kansas]

While recording on tascam analog deck Im getting a low popping noise as the LED registers a very low signal. I'm recording with a keyboard and this problem is only noticed on sustained notes but it is very annoying....any help would be appreciated.

Could you post a short mp3 of noise so we can hear it with our own ears and try to figure this out?

Cheers!

Thanks for responding...I'll post mp3 as soon as possible.
