Erik Satie was a French composer who lived around the turn of the 20th Century and did a number of bizarre things, including the creation of a piece of music called Vexations which was not published during his lifetime but which has fascinated people subsequently. It's a single page of music, written with strange notation, containing an instruction that has been translated as "In order to play the theme 840 times in succession, it would be advisable to prepare oneself beforehand, and in the deepest silence, by serious immobilities." Although what that's really intended to mean is not clear, it's often interpreted as saying that the music on the page should be repeated 840 times, which makes a performance of the complete piece on the order of 24 hours long.

Electronic design is sometimes imagined to begin and end with the schematic. Whoever drew the schematic gets the "designer" credit; hobbyists search the Web for "free schematics" and just assume they will encounter no issues getting from there to a working build; and technical documentation for modules (including my own) focuses on displaying and explaining a clear schematic rather than giving much or any coverage to the PCB design.

The COVID-19 pandemic has made everybody interested in virology, and molecular biology more generally, and one of the cool things about living in the Future is that genome sequences have become accessible. Where it used to be the work of a person's entire career to maybe obtain just a fragment of the code for a single gene, now there are machines that can obtain a complete sequence for a sample in just hours or days. And unlike a lot of other scientific data, it's become the usual practice for gene sequences to be shared. Any ordinary person, not just a capital-S Scientist, can just go on the Web and download the sequences for genes. So here's one of my lockdown projects: using that public genome data for sonification. READ MORE

So, you want a simple digital logic function in a synthesizer. Maybe it's an AND gate, or a couple of XORs, maybe as much as a shift register. How will you build it? READ MORE

I'm preparing for the release of the Middle Path VCO. That should be announced in the email newsletter within a few days. There will be only a few modules available in the first wave so I'm probably not going to do the big public announcement until a few weeks later when I've got more supply; other things going on in the world at this time have created some supply-chain problems for me and that's also one reason I haven't written much new content in this Web log for a while. I'd really like to be able to sell out the first batch of Middle Paths on just the newsletter announcement so that I can use the cash to get more parts for further production. Anyway, one of the last steps in the release process is to write up sample patches for the manual, and I figured those would also make a good Web log entry. READ MORE

There's a lot of talk in modular synthesis circles about what people call "Euclidean" rhythms, which are claimed to exist in most kinds of traditional music around the world. Unfortunately, this concept is often oversold, and presented in a way that makes it sound much more complicated than it is. READ MORE

There are a lot of bad synthesizer schematics on the Web, and it doesn't hurt their popularity. As a designer who tries to get everything right, it's somewhat disheartening to see designs with obvious, simple flaws get built commercially and cited as positive examples - and it's even worse when someone has trouble with one of my modules because they tried to connect it to the latest popular whiz-bang box which has bad levels or whatever and does not play nicely with others. In this article I'm going to talk about some of the problems I see time and time again both in free schematics published for DIY hobbyists, and in commercial modules. READ MORE

In the last several weeks I've been working on development for my next product, which I'm ready to announce will be called the MSK 013 Middle Path VCO. It's planned to be a "complex" VCO design with two independent triangle cores that can be synced, and a special waveshaping section based on the Barrie Gilbert sine shaper modified to produce quadrature output; that makes it capable of some through-zero phase modulation effects even though the cores themselves are not through-zero. I've been posting pictures from my development process in other places, and this posting gathers some of those together. READ MORE

I get a lot of questions about ambient chord progressions. Actually, I don't get any questions about ambient chord progressions. What I get is search engine traffic from people who were looking for that on the Net, and end up reading my old article about fractal chord progressions, which may or may not be much help to them.

The Toronto Sound Festival starts tomorrow, November 22, 2019, at "Beverley Halls" (aka the Polish Combatants Association).  I'll be there as a vendor, with demos and sales of all my modules and kits.  There will also be a lot of other interesting stuff, with other vendors, talks and panel discussions, a "synthesizer petting zoo," a DIY workshop, and a big concert.  There'll be a lot of modular there, but the focus is broader, on all aspects of the art of sound.

The Tokyo Festival of Modular is coming up this weekend, November 16 and 17, 2019, and North Coast Synthesis is a sponsor.  I won't be attending in person this year but attendees will receive North Coast stickers and cards with an exclusive discount code.  If you're in Japan, this is an event worth visiting.

Newcomers who are just getting their feet wet with modular synthesis often ask for summaries of how to build a starter system. There are a few things to understand about that. READ MORE

I'll be exhibiting at the Toronto Pedal and Synth Expo on November 9 and 10, 2019.  Drop by to try out North Coast modules in person and pick up a sticker and a discount code. READ MORE
