One of the the easiest ways to play a sound file in Csound is to use the diskin2 opcode. With it, you can loop samples, modulate the pitch, apply filtering and ring modulation, etc. You go really far with just this mini-sampler. It does have its limitations. The approach of the Beat Mangler X example overcomes them, but requires a more advanced design, which we’ll cover at some later point. Though for many situations, you’ll find that diskin2 is the perfect solution.

The listening example uses the amen loop used in the Beat Mangler X example, though you can easily use your own mono files by making changes to the score. Diskin2 supports stereo files, though this example only works with mono samples.
