i havent spent quite as much time with it as id like, but have not noticed any issues as of yet.
FWIW im really digging it thus far. I feel its far easier to assign CV to FX than the sample drum and is therefore a bit more immediate in regards to departing from the original sound. Rample also feel a bit easier to load kits and get going. there is no set up time at all.
the SD will always win out in regards to slicing though.
