What Flo said.  If you can, it's probably the easiest for you to
record the click track once and mute as needed.

The Click plugin resets to time zero when the host calls its
activate() function.  Although it cannot tell the current transport
position, it should never stutter.  If you've found a way to make it
stutter, please send me a recording of its output and/or detailed
steps to replicate the problem.
