Clicking sound on recordings

[JanCK]

I am attempting to make a "quick and dirty" video recording a song using an iPhone connected to an iRig device so that the sound will come directly from the keyboard and not an external mic.  I thought I had this working, but then yesterday every "take" included a regular recurring clicking sound.  Any idea what this could be and how to avoid it?

Well, I've got the "dirty" part perfected thanks to the click, but the "quick" part is a total bust!

Any suggestions?

Can you send us a recording? It could help us understand better.
