Whether or not buffering is necessary depends on what you're doing. When playing a normal MOD you don't need it, because you simply load all the samples before playing the mod. When you're generating the samples in real time, then you do need to use multiple buffers so that you can fill one while playing the other. The same applies to playing samples that are too large to fit in memory (for example a WAV ripped from CD).
