So, by passing sampleduration to our start: and finish: opts, we can find out the duration of a single slice. This might have not been too noticeable using Sonic Pi on modern computers that typically have incredibly large amounts of memory. There are samples and synthesizers loaded in that you can interact with in countless ways. Let’s combine everything we’ve seen so far into a final example which demonstrates how we can take a similar approach to combine randomly sliced beats with some bass to create the start of an interesting track. This means the code will execute concurrently to the following code after the call to in_thread. After sample you can enter the variable name containing the file path and then the name of the sample. You can use your Raspberry Pi to compose your own tunes or Sonic Pi can also use samples, which are snippets of music that you can manipulate, such as by changing their speed or adding effects to them. Sonic Pi is shipped with a default audio sample collection, containing musical snippets, sound effects and rhythm loops created by various contributors at freesound.org. We calculate the start position s by multiplying the sliceidx by the slicesize. However, I’m also interested to find out more about your use case that involves updating the samples in a given directory. in_thread(&block) Arguments Code block Description Runs the block of code in a separate thread. You can see an example of such a graph at the top of the image above. Before we play the next slice, we need to know how long to sleep, which should be the duration of the sample slice. You’ll get to know two new things: live_loop and sample. There are a wide variety of sounds that can triggered using the sample command, ranging from curious synths to recorded instruments. Build the ultimate media centre in The MagPi magazine issue #102. For example, maybe you would like to record something (like your own voice or guitar) and have it in Sonic Pi to use in your song.
