What are your idle RPMs at?
Each friction plate has a pin on it, which sticks into a groove on the clutch basket. The gap between those pins and the groove they slide into, is where the noise is coming from. The metallic clutch plates make a "ting" noise when the clutch is pulled in. Its the noise we're all very familiar with when riding dry clutch bikes. The moment you put it into gear, everything rattles and thats why you hear that noise. Yes, its coming from the hub, not the basket since the basket is always spinning. But the noise is pretty much normal with dry clutch Ducati's and basket/clutch pin wear.Clutch plate pins? Are those like tangs?
There are groves in the basket from the plate tangs, but the plates themselves are not deformed.
