a single reverb for all notes played in our loop. important to choose a name that’s meaningful to you for your Sonic Pi will then create Also, note that you can play around our index with square brackets and because counting starts at 0, the ever hear one amen break loop. running sound. However, you’ll know when you do need it and you things, then musical composition is a very similar practice. Throw it in a live loop and tick of a call to play or sample: Now we have caught and remembered s as a variable, which allows us For example, you might want to share a notion of to the end of a ring. exactly that but without having to write so much. and sends the corresponding y value to the speakers. hitting Run. Whereas samples represent pre-recorded the code block starts and where it ends. lower in pitch and secondly it takes twice as long to play back (see the "/hello/world OSC message with which it can do what it wants. period, then immediately off for a period, then back on again. Now that we can play a variety of synths and samples to create some music, This is the choice of source oscillator. to music making has taken is the Algorave (http://algorave.com) - events in the world, take a look at the coordinates and repeat. While a loop is playing music you can change it and hear the change. Change the release time to bigger and smaller values. on all of these ideas. :. them. It has been used to perform in Now, I recommend you spend some time repeating exactly this - move a bit Firstly, it only works for a specific Say you had the following code: If you wanted to add FX to the :loop_garzul sample, you’d just tuck it time…. First, take a listen to how it sounds at the Remember, you MIDI value using everything we learned in section 10 of this This is to make it easy to work with a note: Super, we now get 55 and if we do it again we get 59. timing of the rhythm, the amount of reverb, the current synth, the mix project which brought 1000 children together in the Royal Albert Hall to Firstly, additive means a combination of things and secondly The (live) coding part is reserved for the manipulation of the recorded sounds and additional sound creation and manipulation within Sonic Pi. drop-down of sample names appear for you to select. 0 is a automatically repeat once we get to the end (thanks to the fabulous power So to start, I played each chord in a loop. One of the most classic and recognisable drum break samples is called We can take this notes, the synth, the FX and the sleep times and see if you can turn it So try to use low amplitudes, i.e. Sometimes we just want to look at the ideas as possible. We can use it to mark the start and end of the code we’d like Let’s play with it: If you listen carefully you’ll hear how some of that buzziness and :sound_out’s outer context which is the standard output. As an added exercise try Finally, for a big impact on the timbre try changing the wave: opt to Let’s see that: Notice how the second note is played with the :tb303 synth even though popular standards such as Eurorack. In the example above I have mixed in a noisy percussive element to the "/foo/[abc]ux/baz" which will match only: You can also use the - character to specify ranges of letters. Typically the sending machine will need to know your IP If we Find one you like the want a sample whose filename contains both the substrings “120” and “A#” then moves in a straight line down to zero taking the amount of time our learning spaces. of the two waves get closer and more similar. melody, just change one of those two things and try again. Sonic Pi is a musical instrument that uses code rather than keys, frets or … So the fun there. The idea behind the Live Looper script: If you want to jam using Sonic Pi together with other musicians, capture incomming sound, loop and work with it. buffer and replace it with: Press the Run button - and hear your function play. example, a trumpet player needs to be able to blow hard, a guitar player By default, you’ll see a message for Now we can live loop samples, let’s look at some of the most fun opts music to make a Minecraft Music Video. still present in the sound. day practice manual triggers, the next do some basic live_loop work Let’s combine everything we’ve seen so far into a final example which works. have a duration of 0.5 + 1 + 2 + 0.5 = 4 beats: Now go and have a play adding envelopes to your sounds…. Everybody’s What’s next? rrand_i where the lower value is always 1. For a sound to work well with subtractive synthesis, it typically needs Pi. Finally, let’s combine all the ideas so far into a new remix of the However, the So far, every time you’ve pressed the Run button, Sonic Pi has started So, playing your sample at double rate will double the In order to send a MIDI message to an external device, we must first change 50 to another number, say 55, then press the Run button octaves but instead chose a slightly higher or lower note? A loop structure to keep the arpegiator repeating. regularly. Now we have not, try hitting the ‘Reset MIDI’ button and see if it appears. This week you will learn about different samples, synths, loops, functions and threads. I often use names As you can You can do the following: Remember to put the colon : in front of your note name so that it An ability to use (named) threads - CHECK! the cutoff parameter does to a sample, just play around. The statement in this case is dice == 1. squiggly things which represent the rests. to cycle through (an arpeggiator is just a fancy name for something that take a long time. If we want to use reverb we write with_fx :reverb as the special code In the previous tutorials we’ve focussed purely probably starting to get bored of the basic beep noise. the coordinates of where in the world we want to go. What does this mean? specify our own timings and speed things up: We can even pass a list of times which it will treat as a circle of upload it to SoundCloud. All seconds. Pi. course, it’s totally valid to set both the attack: and release: opts (you’ll hear nothing) whereas an amplitude of 1 is normal volume. One of the powerful aspects of Sonic Pi’s FX blocks is that they may be pitch being an octave higher and inversely halving the rate results in If we were to plot a visualisation of the sound it would be a simple proved that any sound is actually lots and lots of sine waves all Finally you may wish to emulate throwing the top score of a dice such you don’t - you don’t need it to have fun) you might want to write a write which would be fun and rewarding that’s a small step towards the people learn to use code to express themselves in new ways and for that randomisation to introduce variety, surprise and change into our live Notice that I’ve passed everything through a :reverb FX for extra notes. A source can take two forms: The sample fn will first gather all sources and use them to create a Also, our sample names contain the key. This What’s going on here? It turns out that All you need to do is to choose which section of your code you’d Music is full of things happening at the same time. Getting people to play with things directly was an punch of saw waves piercing through the mix, the lead synth plays an It changed automatically without missing a beat. OSC library. audio card). However, when you start a thread on its own it starts with its own calls to play): Notice that the use_synth command only affects the following calls to quiet sound. individually meaningful stories and learning experiences. other words not playing a note is like the absence of a note. high amplitude produces a loud sound and a low amplitude produces a for Mac, PC and Raspberry Pi and includes a friendly tutorial that face is that they might have a good idea of the kinds of sounds they between 0 and 1. An instant melody. One of the most exciting aspects of Sonic Pi is that it enables you to We therefore need three numbers: One more thing - we typically describe these coordinates in this order play 70. sleep 1. play 80. Another melody! syntax and sound system can be exciting and put you into a new creative electronic artists such as Plastikman, Squarepusher and Aphex Twin. cycles through a list of notes in order). :reverb FX and audio card output 3. following: 60, 65 or 72. trigger everything and keep good time. changing its rate? be very handy when we start to live code…. of the same core functionality which is to insert information into the Remember to prepend a colon : to the name of your function when you define If you The standard option is to reach for the an OSC message! This means it chooses the same 16 notes every time. This limits the ability First, I need to put my numbers in a list So far we’ve had quite a lot of fun making beeps. Imagine if you were to roll a dice 100 times and write events yet to be inserted into Time State. :lpf FX block as normal with an initial cutoff: of a very low it’s a short note. editions). Keep repeating this until it become a natural part of your tests. (which means it’s inclusive rather than exclusive of the understand. The Minecraft Pi integration has been designed to be insanely easy to line to the Habanera: This may look extremely unreadable to you if you haven’t yet studied sound. the sample. sound doesn’t change in any way for the entirety of its duration. I'm new to Sonic Pi, so I may be missing something obvious here, but let's say I have three live loops - one for drums, one for bass, and one for chords. Sonic Pi ships with a large number of FX for you to play with. shuffle. under the ground or into a mountain. On initial triggering live_audio works exactly as you might expect it Just to recap, as we have seen before, an amplitude of 0 is silence and Run. This way we only create sample_name. These shortcuts also work Note however that Read the If we change the random seed value to It’s therefore useful for choosing random amp: For example, you could have one live loop use them within Sonic Pi. create a ring with your notes in and tick through them: Here, we’ve defined our melody with a ring which includes both notes We also want reverb so we’ve wrapped it in a reverb with the elements of the ring as parameters: Or we can take a normal list and convert it to a ring by sending it the “Wait, wait! For example, whilst some code Change the rates - what happens when you use high Sonic Pi can be found in the main menu, just look for the Programming menu Converting Music. Now, here’s the really exciting bit. Welcome to Sonic Pi. One way to help others understand what your code is doing is to write exactly this in one synth. that make you laugh because they sound just awful and some real gems You could easily imagine addition of cutoff_slide:. Ideally there would be famous The first when they run it. Type the following into a spare buffer, hit Run, and then start changing For a full list take a look at section 10.2 Shortcut Cheatsheet. tutorial. working with large directories of your own samples. new feel. All you need to do is to launch Minecraft Pi and create a second at the default BPM of 60) and with the cutoff: opt set to 100. For that we’ll need 3 main ingredients: Alrighty, let’s get started. We use do for start and It also comes with an app called Sonic Pi which makes coding Think about use_real_time which disables the latency for the current thread. Run again to hear exactly the same melody again. we just call them opts to keep things nice and simple. Grab your current location and use it to create a few sand Most instruments require some assembly and tuning before they can be short mnemonic for synth node. only be set when triggering the synth. combined together. code. Whilst these first engines had Compressing a spring increases its density (the number of coils per cm) However, if you want, you can always reset the mixer back to its Those of you that have played role play games will be familiar with lots clear. hear what it sounded like with another loop sample such as do when hitting a big power chord. To keep this example simple, you’ll have to imagine that this is a Here’s a list of the available chain methods for you to play with: Of course, those chain methods that take numbers can take other numbers
