New Korg synthesiser gallery opens at the Musical Museum

18 September 2024

The Musical Museum (Brentford, London) has opened a new gallery dedicated to Korg synthesisers and drum machines.

The museum's original collection tells the story of recorded and reproduced music. It includes a Violano, a combination of a violin and a 44-key piano which plays itself using music rolls. The Orchestrion from 1910 is a coin-operated mini-orchestra, performing music rolls with its built-in piano, xylophone, glockenspiel, drums, cymbal and triangle. The first thing you see when you arrive at the museum is a cabinet dedicated to Fisher Price toys, including the record player I loved as a child with its colourful disks of nursery rhymes.

Now, the collection has been brought up to date with a room packed with Korg instruments, many of which include sequencers for automating the playback of music parts. The killer feature? They're here to be played! A museum staff member said that you can ask for any of them to be switched on.

As well as modern instruments such as the Volca series of affordable and compact synths, there are classic synths such as the Korg MS-20 (with a wonderful oversized blackboard variant for use in Japanese classrooms), the Electribe sampler, and the Korg M1, which was used on Madonna's Vogue. At the launch event yesterday, visitors had an opportunity to try the PS-3300 recreation for the first time in the UK. This is an upcoming reissue of 1977's ultra-rare synth, used by Jean-Michel Jarre and Gary Numan, now with some added preset buttons to get you started.

The main gallery also has an original 1930 theremin you can play, and a concert hall with a Wurlitzer. This was masterfully demonstrated yesterday with a performance that included a song from The Phantom of the Opera and Queen's Bohemian Rhapsody.

The museum is well worth visiting if you have an interest in electronic music or recorded music. There are three main rooms in the museum, including the new Korg gallery, making it one of London's smaller museums. They are currently running a fundraiser and are interested in meeting new volunteers, so get in touch if you think can help.

Thank you to the museum staff and volunteers, performing musicians and the team from Korg for a great day at the launch event yesterday.

Play my album Artificial, which explores what happens beyond artificial intelligence when the machines get emotions. My novel Earworm tells the story of a record label that uses computer-generated music to manipulate both artists and fans.

The gallery is organised chronologically, with posters and promotional materials displayed above the instruments.

For the first time in the UK, the PS-3300 recreation.

A bank of Korg Volca devices you can tinker with. Some of these are also on sale in the museum shop.

The Korg MS-20 Blackboard version, mounted on the wall. How cool would it have been to have had one of these in your classroom?

Learn electronics and file handling in Python

29 July 2024

Issue 144 of the MagPi is out now, including my cover feature on getting started with electronics and part two of my Productive Python series.

If you're a Raspberry Pi user who's never dabbled with electronics, I hope my feature will give you the confidence to begin. It shows you how to wire up an LED safely and control it from Python. There is also a shopping list of useful components and a guide to follow-on projects you can find online to build your skills. The program in this article turns your LED into a Morse code transmitter. I've extended it slightly to take your text input and convert it into the flashing Morse code. The photo I've used to illustrate this on my site shows strips of paper with Morse code messages stamped into them. I photographed it at the Porthcurno Museum of Global Communications.

Last issue, part one of Productive Python looked at time travel experiments in Python, showing how to create clocks and calendars to help you manage your time. This issue, I shared two programs I've written to automate frequent tasks. The first Python program searches through PDFs (such as ebooks and magazine back issues). The other is a Python program to download web pages and put them into a Word document. The examples show you how to process files and web content, and how to save the output to text files and Word files. I hope these programs are useful starting points for readers as they think about other routine tasks they could delegate to Python.

If you encounter errors when trying to use pip install in an old tutorial (for example Raspberry Radio or ArtEvolver in my free Coding Compendium ebook), you need to set up a virtual environment. My latest Productive Python tutorial also walks you through the steps involved in doing this using Thonny. It's easy, but it's new, so I recommend you take a look if you haven't done it before.

The MagPi can be ordered or downloaded online and is available in newsagents, including WH Smiths.

Time travel experiments in Python

12 July 2024

For the latest issue of The MagPi, I've written a tutorial about creating new clocks and calendars with Python. I've been thinking recently about how Python can be used to improve your productivity, so for this article, I provided some examples of using the datetime module to represent time in useful and inspiring ways.

The article includes a "hello world" example that tells you how many days it is to Christmas. It then shows you how to make a calendar like the one shown on the right, where a bar graph shows how much of the current day, month and year has passed. (Or remains, depending on whether you're a calendar-half-full or calendar-half-empty kind of person). If you're working on goals with a deadline of the current month or year, this can help you to see how much of your available time has already passed, and how much is left.

The second example is a countdown clock, made by wiring up a four-digit seven-segment display to the Raspberry Pi's GPIO pins. By setting this to the end of the work day, you can see how much time is left at any moment. This helps you to choose the biggest task next that will fit in the time available, or can inspire a mild panic to get you moving if you are on an end-of-day deadline that's closing in too fast. With magazine listings, the idea is to keep the code simple. One enhancement I thought of, but didn't include, was for the clock to have different finishing times on different days, because some days I finish at different times to others.

You can download the code for these examples here, and can find issue 143 of The MagPi online or in your newsagent.

You might also be interested in my pomodoro timer for the micro:bit, which also features in my free Coding Compendium ebook.

Issue 143 of The MagPi also includes an article I wrote about Spin, a DJ deck that plays AI-generated music. You use buttons to choose the parameters you want for generating the music and can scratch it using a real record deck.

New 3D Amstrad game: Anaglyph Aliens

19 June 2024

I've written a new listing for the final issue of Amtix CPC magazine, which has just been published. It's a game called Anaglyph Aliens that uses 3D red/blue glasses to make aliens fly out of the screen at you.

I've long held an interest in 3D effects. One of the first articles to go live on this website more than 25 years ago was about stereograms, and my book Cool Scratch Projects in Easy Steps showed you how to make 3D games using Scratch (and included a pair of the glasses).

I was curious about whether it would be possible to create a 3D game for the Amstrad. It all came down to how well the machine's built-in colours matched the lens colours in 3D glasses. While there was some ghosting as a result of colour leakage, the 3D effect worked. I wanted to make sure the game design used the depth as a gameplay element, and not just background scenery, so the aliens fly towards you.

I also wanted the program to make sense as a listing, intended to be read and typed in. In the 90s, listings often had lots of sprite data, which was boring to type in. This wasn't really questioned at the time because there was no other way to get the software, other than buying it on tape which was unviable for most short programs. Now that we can easily download software, there's little appeal in reading or typing in a listing that is unintelligible.

To that end, this listing draws the aliens in BASIC, and then uses a tiny machine code routine to convert them into sprites. I really wish I'd had this idea in the 90s. It would have made Fishtank a more interesting and shorter listing, for a start, even without changing the experience while it was running. Anaglyph Aliens also uses the small machine code routine as music data, so that it's possible to have a (strange) jingle before each game, without needing to type any music data in. (I didn't include this line in the mag version, to save space).

It surprises me when I find myself thinking of a new coding technique on the Amstrad, given I've hardly used the platform for years. It feels like my old programming knowledge from my well-spent teenage coding years is still there, but enhanced by the things I've learned since about user experience and the time I've spent programming in Python and Scratch.

Play Anaglyph Aliens in your browser now, or download the disc. If you don't have a pair of glasses to hand, you can order them cheaply on eBay, or find a pair in Cool Scratch Projects in Easy Steps.

As I said, issue 12 is sadly the final issue of Amtix CPC. For this last issue, I've also written a short history of the CPC seen through the final issues of the major magazines and a Flash Back review of Highway Encounter. Over the last few years, the magazine has published 12 issues, plus an annual, coming to a total of about 750 pages. It's been a joy to read and to write for. Thanks to the publisher Chris, editor Colin, the contributors and the readers for making it happen. If you have any gaps in your collection, back issues are available here.

New free ebook: Coding Compendium

03 June 2024

I've published a new ebook that compiles more than 100 pages of tutorials I've written for Raspberry Pi, Scratch, Python, and the micro:bit. It's called Coding Compendium and it's free to download when you subscribe to my newsletter.

The ebook compiles the articles I've written over the last ten years for publications including The MagPi, Hello World, Raspberry Pi Geek, micro:mag, and my website. A single PDF compilation seems like a more useful resource than having them languishing in the archives, including for me when I need to refer back to a previous coding project to remember how I did something.

In compiling the ebook, I took the opportunity to update my article on using the Python turtle (a great way to move from Scratch to Python), and added a new article about getting Scratch 2 projects working with Scratch 3. Some of the older articles were created with Scratch 2 and there are many great resources available for Scratch 2 (including some of my books which haven't been updated). There are just a few small differences between the two versions of Scratch, so projects from Scratch 2 will work fine on Scratch 3, but some of the blocks are in a different place in the user interface.

I hope that the ebook also promotes the magazines where the articles were first published. While the magazines' licences allow anyone to share their contents, I try to share them in a way that respects the magazine's investment in the work. I don't share PDFs of articles until the magazine issue has long gone off sale, so that there's no risk of my site competing with the magazine. You can support The MagPi by subscribing or by donating when downloading the magazine's PDF edition, and can subscribe to Hello World for free (in print if you're an educator, and in PDF for everyone).

This is the first time I've gated content, by requiring people to sign up to my newsletter to download it. Social media has collapsed over the last year or so, as a way to reach people with new articles and books. I hope that this ebook will help me to build a list of people who are interested in the kinds of things I make and write about, so I can keep them informed with occasional emails.

See more information, including the table of contents.

New EP: Songs About Coding

02 May 2024

I've just published a new EP called Songs About Coding, created with artificial intelligence.

In the last few years, we've seen the rise of generative AI, including ChatGPT that generates text and tools like Dall-E and Stable Diffusion that create images. I combined them for my Bedtime Stories project. Now an app called Udio enables you to create complete songs based on a text prompt, including the lyrics, melody and musical performance.

It's more audacious than I dared dream when I was writing my novel Earworm, originally published in 2007. In the book, a record label comes up with a way to create computer-generated music, tailored for each fan. The book predated the rise in generative artificial intelligence, so the story uses a combination of technologies including lifting blog posts for lyrics, using melodies created with a decades-old type-in program, and naming bands after spammers, who were prolific then and often had highly amusing names.

Crucially, in my story, there still needed to be a human element. Is that the case now, with the rise of AI?

I tasked Udio with creating a series of songs in various styles about coding. In particular, I prompted it to create an 80s pop song about programming the Amstrad CPC computer, an acoustic song about debugging, and 1950s style songs about the Raspberry Pi.

The results are impressive. I did do some editing to fix the song structure, but I've featured some of them without any changes (apart from mastering).

Technologies like this are empowering for people who want to make music and don't have the skills to do so. You can give Udio your own lyrics, so if you're a lyricist without a collaborator, you can still create finished songs. As a musician, you can create music or loops that you incorporate into your own creations.

However, it seems likely that this will take work away from some professional musicians. Those working in library music and commercial commissions seem most vulnerable. Illustrators who are members of the Society of Authors are already reporting that they're losing work to AI.

Listen to the EP here! It's a fascinating demonstration of what AI can do today and it raises many questions. I woke up this morning with one of the songs in my head, so they're quite catchy, at least after a few listens.

New visualiser for Out of Mind

22 February 2024

I've released a new visualiser for Out of Mind, one of the most popular songs on my album of electronic music Artificial. The album explores what happens beyond artificial intelligence, when the machines acquire emotions. The visualiser provides a convenient way for people to play the song on YouTube. There are now videos or visualisers available for Out of Mind, Broken Shell, Input/Output, and the near-final ambient track Waiting for GOTO. See all the videos and play the album here.

I also released a companion EP of tracks that didn't belong on Artificial. That EP Is called Artificial Additives and includes an early poppier version of Out of Mind. I made a video for the track Do This that shows my film of the lifeboat coming in at St Ives.

Both the album and EP are available to buy and currently available to stream at all the usual places.
