Rytm sample tuning not functioning

I never really use the sampler with the rytm (dont think I have since i upgraded the OS). the tuner knob has no effect on my samples right now. Is this a known bug? Confused as hell

what knob - have you turned on the toggle so that samples will also be affected by chromatic playing ? (Fn+Sound then Chromatic = Sample or Syn+Samp)

but the +/-24 tune parameter on sample page should always make a difference

Yep - it was the paramter knob on the sample page. I reloaded the kit and now its working. However the looper in the sampler isnt working. I can see on the new wave display screen that the loop is running but I hear no looping audio.
