It has been a couple of months since it has been released, but I never did the shameless plug in here so here it goes:
I have gathered the outcome of my FAWM 2008 participation and put it on a nice CD format and it is available for sale through CD baby. So… if you are feeling adventurous, why not buy it? is cheap!
Here are a couple of full tracks, for your enjoyment.
The Gakken SX-150 is a really inexpensive analog synth (about $50, now available at the make store). This synth is included on a Japanese magazine (I wouldn’t expect less from them) so that makes it 2*2 times as cool.
Since its release, someone already has created a module to add midi support to it using the atmel attiny2313, but I’ve wanted to use an Arduino board to do it, to keep things easy to prototype and hack.
My implementation uses a single DAC IC chip, the MCP4921, which sells for about 2 bucks from Mouser. The current version uses the Arduino, only to read one byte, as a midi note, from the serial connection and sends that to the SX-150. I could have created the full midi circuit to make it a standalone solution, but that increases the cost and complexity of the physical connections. I’ll probably do that on a later revision.
So, in order to receive midi data, I wrote a small Processing sketch that receives midi, and sends the note information through the serial port to the Arduino.
The Arduino connection diagram looks like this:
And the final connections, like this:
And.. the whole thing sounds like this:
On the video, I’m using Ableton Live to send midi data to the processing sketch using a Network Midi connection on the Mac. On windows, you should be able to use Midi Yolke to accomplish the same thing. Then, I make sure that the processing sketch receives midi on that same virtual midi connection and sends the data through serial to the arduino. So, depending on your system configuration, you might have to tweak the Processing sketch a little bit to make sure it is reading and writing to the right midi and serial ports.
The flow of data from the sequencer to the synth looks like this: Ableton Live => Virtual Midi Connection => Processing Sketch => Serial Port =≶ Arduino => DAC => SX-150
So I started learning a little bit of Processing and as a first exercise, I wanted to do a visualization of the midi data from one of my songs. The most common midi library used with processing was not able to detect midi inputs on my mac, so I had to write my own class. I’m putting the code in here hoping that it can help someone else.
FAWM (February Album Writing Month) is a yearly community challenge to write 14 songs (a complete album) in February. 14 songs, that’s a song every 2 days, at least. This is the perfect excuse for me to produce stuff, no matter if it is good or bad. Here’s what I’ve done so far (this list will get update as February goes along.)
IDE’s: you either love them or you hate them, but there is no question about it: they do make a developer’s life easier. Developers that are really good with such a tool can seriously count on them being an extension of their body, an invisible limb, a partner. They physically hurt when the IDE crashes, they clean it, take care of it. But is this good or bad? Are developers leaving part of their brain on software? I think so. The worst part if they leave it there for too long they might not get it back.
Technology changes way too rapidly for programmers to develop such a strong relationship with a tool like this. Is this relationship beneficial? Absolutely, but you have to be ready to dump your software partner at a time when you least expect it. I know of stories where broken software hearts means having to change jobs.
The beauty of this relationship is that cheating on your IDE does actually benefit you as a developer. Besides, the IDE won’t get mad at you, even if it finds out. So my fellow developers, free yourselves. Play with other IDE’s, languages, techonologies and don’t be afraid. Times change rapidly, embrace change.
I just came back from another great High Sierra and saw some excellent bands, but the ones they always stick up are the ones that do something unique. This year, the uniqueness prize (i.e. ultra-super-freak) went to That1Guy.
His main instrument is a home-made invention he calls “The Magic Pipe”, an industrial looking steel pipe contraption that has two ends, where he either plays bass or lead (and he is pretty damn good at both). The 2 strings have an amazingly natural envelope filter like sound, which comes out just as if he was playing a synth bass.
Apart from the strings on the pipe, he has an assortment of midi sensors. There are 13 of them alone on the Magic Pipe and who knows how many more on bass-drum-pedal-driven-cowbells and a single snare that gets no compassion during the live show.
His music is a refreshing mix between crazy funk and industrial, that can easily drive a crowd insane. And, the lyrics are a perfect extension of his instruments: definitely nuts. Don’t believe me? check out this video.
I wrote this little game a couple of months ago and get a kick out of it every I see the main page. It is a clone of the JawBreaker game that comes with PocketPC, but I changed the “balls” with some friend’s heads. If anyone wants their own custom version (with the heads of _your_ friends instead) drop me a line.
