# Sample Parameters: Amp and Pan

As we saw with synths, we can easily control our sounds with parameters. Samples support exactly the same parameterisation mechanism. Let’s revisit our friends `amp:` and `pan:`.

## Amping samples

You can change the amplitude of samples with exactly the same approach you used for synths:

    sample :ambi_lunar_land, amp: 0.5

## Panning samples

We’re also able to use the `pan:` parameter on samples. For example, here’s how we’d play the amen break in the left ear and then half way through play it again through the right ear:

    sample :loop_amen, pan: -1
    sleep 0.877
    sample :loop_amen, pan: 1

Note that 0.877 is half the duration of the `:loop_amen` sample in seconds.

Finally, note that if you set some synth defaults with `use_synth_defaults` (which we will discuss later), these will be ignored by `sample`.
