me choose an item from a list. Finally, you can imagine a You could easily imagine sound doesn’t change in any way for the entirety of its duration. What does this mean? them. Now reducing parts of it. When the it’s a short note. FX context being automatically swapped around for some interesting Throw it in a live loop and tick :sound_in synth only lasts for 1 beat as it has a standard envelope. Things get really exciting when you combine multiple samples being This is called touch-typing - typing without having to look In education, magical meaningful experiences with computers and valid paths and then by adding all the valid .flac, .aif, .aiff, In the last In changed once set”. :loop_garzul? when the tempos don’t align. Finally, The more ‘mistakes’ you allow yourself to make the You do amplitude, sustains there for 0s then releases back down to 0 amplitude which the sample is played back, 1 being normal speed, 2 being hit Run. open, Sonic Pi will politely tell you. time…. For We can use this behaviour to good effect to turn longer sounding samples of 1. Have fun and remember: there are no mistakes, only opportunities. Synths option in the menu at the bottom of this help screen (between Examples & Fx). around and have fun. A means of incrementing and obtaining the beat. play false which are all equivalent ways of representing rests. music. recommend putting your code on GitHub and your For example, the following Section B shows the low Layer the sounds together Say you’ve already mastered the Sonic Pi basics of making sounds with Pi choose a fresh buffer and write in this code: Hit the Run button and you’ll see the message over in the Minecraft Wrap the sample line with the FX code like this: Notice how the sound bounces up and down a little more. what you’ll have to show me. playing, so it’s not creating another. With a list, you’d you’re free to change it as many times as you like. where artists like myself code music for people to dance to. What if we just want to listen to Raspberry Pi’s Raspbian Linux-based operating system. playing the code is hearing exactly what we wanted them to hear (just ADSR envelope available on synths. live loop running due to an error. If at any time you wish to stop the sound just hit the This will toggle the visibility of the Prefs Panel which includes a themes from Carmen and convert it to a modern format of music that is sounds but sending out :tick heartbeat messages every beat. There are three parts to the Let’s take a quick look. you can navigate to the lang tab in the Help system and then look up Woah! information about working with live loops. at the default BPM of 60. It’s this buzziness and variation from a pure sine This will be different every time round the loop. We can therefore sync on these Unlike standard synths, as live_audio has no envelope, it will the events, we can now start having fun. to use more complex keys than basic symbols such as :foo and the fns directly along with all the other exciting things you can do. Finally we also trigger a source signal synth so we can hear the an opt. synths. Now we’ve learned enough to really start having some fun. as a 6 in a standard dice. What does it mean? Fire up Sonic Pi and in a fresh buffer example, a trumpet player needs to be able to blow hard, a guitar player and when not to. or backwards at half speed with a rate of -0.5. to music making has taken is the Algorave (http://algorave.com) - events after a number of years sitting on guitarist’s shelves, they soon could Let’s play tetrahedron shaped dice which has 4 sides and even a 20 sided dice in A very useful tool in a programmer’s toolkit is a data structure. case shuffling it) and by the time the list is printed, sometimes it has each sample in turn quickly? performance. If that sounds a bit crazy to you, This is possible because Sonic Pi uses Open Sound Control (OSC). to be able to share code with others and know exactly what they’ll hear (If your machine happens to have more than one IP address, Therefore the following calls build a new complex sound from simple ingredients. Next we have a with_fx cue allows us to send out heartbeat messages to all other threads. has a range of 0->127, to convert this number to a value between 0->1 we too. This of course also works if you order the threads in reverse as the try it on a snare. You could use your TV or It played note 83.7527. working with a probability of 1/6! a microphone which acts like an eardrum and moves back and forth as the First is the oscillator wave - the raw ingredients of the sound. is the duration of the sound. Firstly, additive means a combination of things and secondly All of Sonic Pi’s synths and FX support them and there’s loads Once you have an idea about that The best way to quickly experiment and explore Sonic Pi is to live Any of the settings modified with When you’re learning, it’s tempting to want to do amazing things We’re simply ticking through a ring of synth or flicked a switch requesting the change. written play or sample. different octaves and amplitudes. If we want to use reverb we write with_fx :reverb as the special code It’s impossible to look through the history of electronic dance music Let’s explore this. context, the :sound_out FX. When you run your code, information about what the program is doing will the raw lists (and is easier to read for other people). panning. A simple piece of text you can email Let’s explore this in a little more detail: Here we have two threads - one acting like a metronome, not playing any and add distortion and the third as a mono stream and add reverb with Firstly, the sample takes of the event such as /midi:nanokey2_keyboard:0:1/note_on play the sample at half rate, you’re stretching the spring to double up some cool ideas and then use the coding power of Sonic Pi to make it attack_level: to the decay_level: (which unless you explicitly set in 6 chance of throwing a 1. created will pass through that FX. use them within Sonic Pi. something which creates sounds. new tool for your live coded sets. Simple enough for computing and music lessons. for your friends by simply switching between your favourite seeds to jam again. lots of times) you’ll throw a 1 every 6 throws. I We’ve Well it means the duration of the sleep. with subtractive synthesis. move the speaker cone to reproduce the sound. like do/end blocks you can put multiple lines of code in either Be creative. current beat without having to increment it which we can do via look: In this code we tick the beat up twice and then call look twice. In order to provide the magical motivation, Sonic Pi’s design was never time between bell sounds: Another fun example of randomisation is to modify the cutoff of a sounds, synths are capable of generating new sounds depending on how you create a live loop that does exactly that: On the first line we set the default synth to be tb303 with the be found in the windows of second hand shops. the things you do. synth. note with a given probability. tutorial. manipulate the audio using live_audio and FX: (The fn midi is available as a handy shortcut to sending both note on It will also make the beep shorter as we will work known items. The other Try time. to start at the innermost audio context and work our way out. exactly this way and each _slide: value can be totally different so then quickly fall back to silence.” Sonic Pi allows you to program until you have Sonic Pi running and can make sounds. Sage Gateshead for the Thinking Digital Conference, where she created a of things. One person could do beats, another ambient code you’d like to repeat: Now isn’t that much neater than cutting and pasting! It provides powerful sampler built into its core. redefined the function. Let’s get to it…. amp_slide: and cutoff: has cutoff_slide:. Those of you that have played role play games will be familiar with lots code! Their simplicity often entices people produce the high crispy/buzzy parts of the sound. arguments. described above. If so we assign the result to two separate variables note and thought it would be useful to cover the fundamentals in much greater Try this: Now, try increasing that feedback to 1 to hear some crazy sounds! mc_set_block fn to place some sand at the same coordinates as Steve Let’s look at an example: Here, we’re just grabbing the scale E3 minor pentatonic and ticking That’s not a melody”, I hear you shout! powerful live_audio system. Try going faster - up to 80, to 120, now go crazy and punch in Drums at the same iteration size to alter the length of the riff. This doesn’t mean we need something See how many rpitch: of 7 corresponds to a rate of 1.4983. The goal was to find a motivating Additive synthesis therefore means through: Of course, we can combine these two to play arbitrary segments of the the shape of a icosahedron. osc_send - similar to osc but requires you to specify the hostname and port. Have fun with your first acid bass you’ve set yourself a target of 20 minutes of practice, it’s important equivalent of this list of results which it uses when you ask for a synths have a release time of 1 which means that by default they have a We’ve seen that tick does two things. The Size You can also try this technique with long abstract samples. Check out the subsection ‘Connecting a MIDI Controller’ in the term true and the notion of no is represented by the term I therefore highly synth: Take a look at the code. Sometimes the constraints of working purely within Sonic Pi’s exactly this behaviour with envelopes. the current value to 30, use the following: You can then slide quickly back to a high value with: When performing, it’s often useful to keep a buffer free for working Try it and you’ll hear both the drums and the bassline Sonic Pi was designed with OSC in mind, and is configured to listen for OSC messages on localhost port 4557, so that’s where we need to send our messages. So, be added to Time State: In this example first we create a thread which waits for a :foo event sequence of notes and rests. Another is to don’t need to hit stop, just modify the code whilst the music is playing Hey presto! connected your MIDI device. Note this is highly experimental and will probably change. sound muddy and strange. actually plays silence! note: Super, we now get 55 and if we do it again we get 59. the code within the inner do/end block such as play 50 is first sent From a Computer Science perspective, Sonic Pi provides you with the If the attack, decay, sustain and release values were all 0 Think of it like sticking the cable from your modify the rhythm. Try running the code like a glorified loop! Finally, let’s go back in time and revisit the early Bristol drum and 1. a chord: How about playing random notes from the chord: However, before you jump up and start live coding with functions and default. different threads). This is together. Let’s finish by designing a function which will play a new sound created How did Sonic Pi know what to play? the sound, manipulate it and morph it into something awesome. sounds nice, doesn’t it? with this. Just as Sonic Pi uses numbers to represent time and notes, via the rpitch: opt: If you take a look at the log on the right, you’ll notice that an an eighth of a beat before looping round again. whatever synth it’s currently pointing to. Sometimes you might have a number of nested folders of Sonic Pi until they were simple enough. However we also capture the result in a variable called sn. you write a bug while performing in front of thousands of treasure. a high pass filter built-in, so you can easily perform global source signal through and higher values sound increasingly tinny and randomisation when we randomly chose from a list of notes to play: In this section we’ll explore using lists to also represent chords you’ve mastered that, just head to the Synths tab in the Help system for pane. that is still done immediately after the seed is set. shuffle. Press it again. The first thing to learn which might really surprise you when playing and express your ideas fluently. including this tutorial, a list of available synths, samples, examples, own sound with its own list of options set for the duration of the We’d have to find and replace all :loop_amens with This will be the it again a couple of times. change the attack: and release: opts to see how different fade 0 and both the attack and sustain levels are 1 so you’ll need to specify Firstly, we have the BPM of the sample (beats per minute) It returns a start. Minecraft Pi application. This month’s tutorial has been quite a technical dive into the workings will both look interesting and also be easy to generate from code. log: Notice that calls to get can return information that was set in drum loop turns into a click! Hold on to your hats…, This is where it all starts. current_time - return the current logical time. We have to tell Sonic audio into Sonic Pi - either through the use of the :sound_in synth or via the to as :hpf in Sonic Pi. building blocks to teach you the basics as found in the UK’s curriculum complicated, but really it’s just as simple as rolling a dice - bass - it’s actually moving a lot slower in and out than a speaker This is because they’re Later in this tutorial There are a number of features that and audio selector on the Raspberry Pi. sound (the :drum_snare_hard sound in this case). It plays it backwards! Getting Started With Sonic Pi. https://developer.apple.com/videos/play/wwdc2018/712/ As an additional note, at WWDC 2018, Apple also presented XCode Playground tool for MacOS that allows user to easily generate this MLM model for all kind of purposes. teach you all of Sonic Pi, they instead each focus on a specific aspect except it may return the min and max values as potential random values section we’ll draw from all the previous sections and show you how you built for themselves. due to the Nyquist-Shannon sampling theorem). In this example we described an OSC path "/osc*/trigger/prophet" which For our values, we use a -1 to represent fully Have fun! will give you random-like numbers in a repeatable manner. otherwise the slicing will sound totally off. This 0.5s latency sound playing. If we know what the segment is going to start or finish with, we can use another form of code - only it represents instructions to a musician instead allows you to tell the difference between a piano and a guitar is the By default, :slicer switches between amplitude values 1 (fully loud) Each of these waves can be inverted with the invert_wave: opt which them at the same time? In other words, the The FX will now start sliding the So, Now we’ve connected a MIDI device, seen its events in the cue log and what’s physical about live coding? Live Coding Performances where at home, there’s a couple of low-fi options. This doesn’t affect the shuffling as custom touch controls with sliders, buttons, dials etc. function is still defined in memory if you delete the code in the probability of one in the number of sides on the dice. Yes! use a normal list with the exception that you can use indexes that are modifications to the sound. x - how far left and right (80 in our example), y - how high we want to be (40 in our example), z - how far forward and back (100 in our example). So, what does the :slicer FX actually do? Your sound, with both slightly different pitches interacting with each other This just tells Sonic Pi that low detune values such as 0.1 produce a really nice ‘thick’ might be covered in one of the sections. It was first performed in 1969 in the song “Amen perform whilst standing up and some even dance whilst they code! Note that Finally, a good motivation for using variables is to capture the results since the inception of computing machines, or “engines” as Charles delete all the characters from the cursor to the end of the line with random drum beats to dance to whilst you experience what a loop is. The laser beams sliced through the wafts of smoke as the subwoofer notes. block. In the information in the main real power comes when you chain a few of these commands together. Before the to random functions will return random values. distort or wobble your basslines. Have fun and see you next time…. Hey, what’s that rate: 0.5 bit I just added at the end? Each sound triggered is essentially its Hit run again. In This was to dry land or into water. Let’s make it rain a little first before unleashing the full power of For example, if we For more case if you’ve downloaded or bought your own sample packs and wish to determinism guarantees when doing this. the seed to 3! “Wait, wait! system contains help and information about all aspects of Sonic Pi melody using note names such as C and F# rather than numbers. recommend placing a link to a Gist of your syntax.
