I select "5-Drum Rack" as my destination in the upper "midi to" drop down. By default the lower drop down selects "Track In". Everything works fine like this.

If I now select "Drum Rack" in the lower drop down... everything is still fine.

The problem comes in here. Select a specific destination in the lower drop down... for example just the kick drum slot of the drum rack and a bunch of noise is now introduced to the drum sample. It makes the sample sound bit crushed and very lofi.

Can anyone reproduce this? I've sent a bug snapshot.
BTW I've just dragged in one shot drum samples to cells on the drum rack, so samples are playing from the default simpler. Original samples are 16bit 44.1 and Live session is also at 16bit 44.1.
