The short answer is Yes.
The long answer is that you need to extend the lowest octave of an 8' set of samples to 16'. To do this with high quality you need to do a synchronous FFT translation for all the samples of each note. This is tedious because for a wet surround set that means the front and rear sustain samples as well as all the front and rear release samples. For the Velesovo that is 12 notes times eight samples equals 96 translations. It's especially tedious to use this new rank in Velesovo because it is not easily used in CODM since the samples have a non-standard naming convention.
