Firefly's tone generator - clicking sound

hi all,

i was playing some with tone generator of firefly but there is annoying clicking sound when the frequency changes every time. is it normal or is it about my system? i was also about to upload a sound sample but it seems it’s not allowed.

i am getting same clicking sound with just a slider connected to tone generator, but i uploaded my file here also.
