Seems to be straightforward, but I cannot find this information anywhere, it has been asked in forums, but the question was either missed or intentionally dodged.
Is CTC-1 using internal oversampling? If not, how does it avoid aliasing? Especially in a full mix context, when you have a collection of all frequencies, aliasing is very easy to happen with anything that adds a few harmonics, avoiding those is a must to avoid that fake digital sound, with unrelated harmonics mushing everything.
