I understand, one thing is an audiofile (it means real guitar, drum?) which takes 7, 5mb per minute, but another one is software instrument file (track, song), which adds small amount mbs to the size of a project. Correct? So, if I will not use the real instruments, I don't have to worry about the use of a memory, OK?
Is track and an instrument the same, and a song and a project the same?
