Topic says it all really. Rendering, sampling and mixing.
Hard? Easy? Can it do it already? Did I bother to check it out? No? How?
Renoise running 96k/24bit would put it in pro league for sure. Maybe even 196k sampling… if yer brave.
It renders in 32bit/96 khz plus it has Argurus legendary “sinc interpolation” (!?!?).
It damn well kicks the butts of the finest already 
Not all soundcards support 32bit float appearantly but IMHO 24 bit is old fashioned and it consumes more cpu power since 8 bits per cpu cycle have to be wasted. But programs don’t waste it, they interpolate it up to 32 bit or truncate it to 16 bit. 24 bit is obsolete.
