I'm guessing, but if it's got the usual triangle/square integrator- 
based LFO, it could be that some of the square wave is leaking into  
the triangle output. That'd cause a regular ticking at the LFO rate.  
The best way to check would be to have a hunt around the LFO with a  
scope.

Hope this helps,
Tom
