Arduino Pedal Fighter project I’m looking into building a MIDI foot controller that works something like the MIDI Fighter but for your feet. The idea is to use momentary arcade-style buttons just like the MIDI Fighter. There are a few problems with doing that though. One is that the arcade buttons are not very low profile. They are designed to…

Tube circuit experiments Here at Audiodestrukt, no esoteric and potentially aurally destructive technology goes unexploited, even those technologies that are over 50 years old. Well, in this case the parts I’m using are modern versions of the early stuff, but it’s still pretty cool. I had some 12AX7 preamp tubes on hand and after running across this tube headphone amp…

Guitar tech – Ibanez Artist I just got my Artist cleaned up and put back together again with the Gibson humbuckers that I got for it a few years ago. This project has been sitting around on my bench for a long time now, so it feels good to get it all done and out of the way. The back…

Korg – the old new thing I’m digging some of the new stuff that Korg is putting out. They have always been one of the most innovative gear companies in my opinion. I’m not a shill for them, I’m just looking out for cool stuff. Some of the boutique synth makers like Dave Smith instruments might have some flashier stuff,…

Duncan amp schematics I have been rooting around in my files to find all of the stuff that I gathered years ago for the Seymoure Duncan amp project. I have some schematics that are the same as those found on the diyguitarist site, but there are 2 that I found that I can’t find on the net, so I scanned…

Duncan convertible amp restoration I’ve had a 100-watt Seymoure Duncan Convertible amp head in my collection for a few years now. A friend of mine convinced me to pick this amp up on eBay since he had one and loved it. My particular amp was working but in need of some love. Well, I never got around to doing much…

MIDI over Websockets with Socket.IO In my last post I outlined how I used curl to send MIDI data over HTTP to a web app. The problem with this design is that HTTP has a lot of connection overhead that contributes to latency problems. To address the latency issues, I set up the Node Web application to use Websockets for…

MIDI over HTTP with using ALSA and Curl A few weeks ago, I created a small Node app called Dub Siren to demonstrate playing audio under Node using SDL. My plan was to expand the idea into a more fully-featured (musicalinstrument">sampler). One of the things that I wanted to check out was the audio latency) between the time a request…

SDL audio in Node.js I was looking around for a way to play sound from Node.js and found out that there is now a mixer/">SDLmixer module for Node.js. Previously I had looked at Irrklang and the corresponding Node module but I never felt that crazy about Irrklang. A while back I was following the development of JSONLoops, which is how…

Barebones Arduino While waiting for my Arduino Uno to show up, I thought I’d explore the Arduino ecosystem a little bit. I had an card.asp?partid=3301">Atmega48 chip lying around and I wondered if I could get it working to play around with AVR development in the meantime to familiarize myself with things a bit. After some research, I found that I…
