North Coast Synthesis Ltd.

This is Part 2 in a series that started with Part 1. READ MORE

The Solstice is rapidly approaching and I'm doing my usual routine of putting off making any plans until the very last moment, then panicking, buying a bunch of random gifts, and handing them out with little regard to who's receiving what. I've come close to the point of That's it, everybody's getting Sine Bank kits! Whether they are into SDIY or not! already a couple of times and it's only December 3rd. If, however, you would like to do things in a more careful way than I do, and if you have a modular synthesist on your list, then you may appreciate these gift suggestions. READ MORE

My mother asked me to explain what I'm up to in one sentence, for inclusion in the annual Christmas Letter, and I said that I'm making electronic musical instruments. That's a pretty good summary as far as it goes. But people often want more detail on what modular synthesizers are all about, and this is the first of several postings I'm writing so that I can have a place to which I can direct the curious. It's largely based on a series of postings I made in my personal Web log about a year ago; the version here will be updated a bit to take into account subsequent developments in the modular world.

Modular synthesis involves a lot of on-the-fly experimentation with the hardware, but if you're going to make music in a preplanned way, there's a good chance you will end up involving a computer and connecting it to your modular via MIDI. Here are notes on some of the software I like to use for that and related tasks. I'm focusing on stuff that will run under Linux, but many of these packages are cross-platform. READ MORE

The Leapfrog VCF does not actually go "ribbet," at least not without some effort. But after being told by one friend I showed it to that most people don't want to make real music with their modulars but just want something that goes "uuuuuuuuuuuLAAAAAAAAAAAAARGH" (which, let's face it, is true) I've added a demo highlighting that. Uulargh? Yeah, we've got this. READ MORE

It's just one thing after another with the Leapfrog. I'd been hoping to have them for sale by now, and I am getting close to that point. I actually have the stock of the first batch on hand and ready to sell now. But there's still a fair bit of writing to do on the manual, final checks to make sure all the drawings are up to date, a press release to write, and so on. I'm working on an ambitious demo track with about 20 multitracks of different instrument sounds all made with the Leapfrog, and that's taking longer than I had planned, but I'm learning a lot both about the Leapfrog and about synthesis in general doing it, so I thought it would be fun to go through one of the patches I'm using. The score calls for (General MIDI) "tubular bells"; here's my take on a sound something like tubular bells made with the Leapfrog, and some notes on making bell sounds in general. READ MORE

You've probably noticed that although resistors and capacitors come in many different values, some of which seem like they could be randomly chosen, there's nonetheless some sort of logic to it. You'll see power-of-ten sizes like 1kΩ, 10kΩ, 100kΩ and it's understandable that those would be "round" numbers it might be convenient to use and manufacture... but for instance there also seems to be something special about the number 47, so you see many resistor values like 4.7kΩ, 47kΩ, 470kΩ, and capacitors like 0.47µF and 470pF. Why 47? Why not 46 or 48 - especially when 47 is a prime number and 48 has many small divisors, which would seem like it might be convenient? Here are some notes on the commonly-used numbers and where they come from. READ MORE

The panel contractor says they dispatched the first production batch of MSK 007 Leapfrog VCF panels to me on Friday, and those are the last remaining physical items needed before I can launch the module; so I'm still hopeful that I can aim for a launch by the end of the month.  That means I need to finish up the last few documentation items; one of them is a description of the exponential converter temperature compensation circuit, and that's an interesting enough item to be worth a Web log posting of its own.

I've spent most of this week working on the second and third prototypes for the Leapfrog VCF. I'm hoping to have this product available for sale by the end of the month - maybe in time to have some kind of spooky Halloween tie-in for the launch. READ MORE

Here's a diagram of something called the CNO process, encompassing many of the nuclear reactions by which stars shine. READ MORE

For this week's Web log entry, I'm digging into my back catalogue again to look at some of the geometry behind the Black Swan Suite. This is all written up in a PDF file with some musical notation and stuff that doesn't work well in HTML; read that if you want details, but I'll give a taste of the construction here. READ MORE

North Coast's first fiscal year ends with this month, and I have a bunch of small news items and progress updates. READ MORE

I make a lot of music that is intended to be "ambient": something you can put on in the background and have it create a mood without demanding conscious attention in the foreground all the time. I'm also interested in automatic generation: I'd like to define some kind of pattern or structure and then have machines expand that into a complete composition, and have it be interesting all the way through, without too much human supervision. In this week's entry I'm going to go through a piece called Dharmapala which I wrote a couple years ago using a fractal chord progression. I've used this same technique in several other works, with varying success; I even built a mode for it into one of my homemade modules for realtime performance. But so far I've gotten the best results applying it in offline composition with a lot of careful planning and experiment. READ MORE

This week I'm planning to order the prototype boards for the Leapfrog Filter, and it makes a good opportunity to go through some common questions beginners ask about shopping for PCBs. When you go to buy PCB production services you're typically hit with a form asking you to select which features you want, and it's not always clear what the consequences of the different answers may be. In this entry I go through some of those options, and give some other notes on shopping for PCBs. READ MORE
