This service specified in this page is aimed at beatmakers or composers who wish to focus on their productions and to delegate the mixing work of their compositions.
The tracks must only contain sound sources from music instruments (virtual or not).
The goal here is not to modify the mix after the "Rec" session. It is rather to develop a composition so that its author can promote and expose a neat work.
The file that will be provided for the beat maker's mix will be in .wav format with 16 bits 44100hz.
Combined with voices, it can also serve as flat work before the actual mix (which in turn will be performed with separate tracks).
