# How Do I Make a Simple Sound?

To produce a sound, you need to do the following:

1. Load one or more digital signal processor (DSP) instruments by calling `LoadInstrument()`.

   DSP instruments are programs that run on the DSP. They provide the functionality of oscillators, filters, envelopes, sample playback, and so on.

2. Connect the inputs and outputs of the instruments by calling`ConnectInstruments().`

   This action is similar to patching a modular synthesizer.

3. Connect to an instrument that can make the sound audible, such as `directout.dsp`.

4. Call `StartInstrument()` to start executing the DSP instrument.
