I went back in and spent a good long time glitching my Casio CA100 again to provide you guys with another glitch library. I am very pleased with the variety of sounds from this machine. I recorded them in pro-tools at 24b 44100khz as mono wav files. there is 106 samples, as of now it is my largest circuit bent library.
This is a program I created that allows you to add some randomization to what you play. It waits for a MIDI message in, then alters that note up a perfect 3rd, a perfect 5th, a perfect 7th, or an octave, also it is velocity sensitive and is polyphonic! I wanted to add more controls but as they say “keep it simple, stupid!” I planed on adding the other intervals but wanted to share what I have with the world! Shoot me an e-mail with any suggestions, and I will be more than happy to add them to the program. Watch for updates and new versions.
Updates coming soon!
- More Intervals: minor 2nd, major 2nd…. diminished… (As of now, it supports perfect intervals.)
- Color coordination for diminished/augmented/major/minor/perfect inversions
- Negative inversions: octave down…. perfect 5th down… etc. (Currently, it adds value to the note you are playing.)
PRI nanoKey edition allows you to turn on/off the three middle controls with the pitch down, pitch up and mod buttons on your nanoKEY controller
Listen to “C,D#,G#” a quick song I made with the PRI pressing only three notes C, D# and G# making the Cm chord. I recorded some loops in Abelton and threw on a beat. I had the “octave” and “5th” settings activated during this song, there are 4 different MIDI loops. Enjoy
Here is a Collection of samples from a few of my own circuit bent toys. I’ve made a quick couple of videos that will show you the method of how I captured these samples. I edited them in Protools at 16bit 441khz as mono WAV files. Feel free to comment or request any more. Enjoy.
Here’s a video of my toy car, it has 8 samples and two sensors, a light sensor and a potentiometer to control the sensitivity of that light sensor.
Here is a video of my drum machine it has a tone bend and an on of switch for that tone bend.
This is my speak and spell it has 2 momentary push buttons on it. One of them plays a random letter from the alphabet, (at one time i had this connected to a blinking led so it would trigger at each blink) The other button loops a few millisecond sample of the letter being spoken until you let go. You can create cool sounding pad sounds sending this into various effects.
The toy above is my Phonics Board. It has a light sensor on the top left near the speaker and a control switch to that sensor also a tone bending potentiometer .
Here is my Musini, I have added a glitch button and a tone bend. I really enjoy this toy because it has such a vast variety of sounds with a really large frequency range, and most of the glitches are FULL of harmonics so filtering them can make some dope instruments!
I will be updating the Library frequently so watch for updates!
2.Pick some parts to add to it – I am going to add a pot and a switch to this
3.Open her up. – It may be unwilling the first time but after that its easy
4.FIND A BEND – This is the most fun. there are several meathods to this, I just use alligator clips to touch around various spots on the board. After messing around with dozens of kids toys you start to see patterns as to what causes a different glitch. here’s a couple other guides if you are really interested The Art Of Circuit Bending F.A.Q.
In this toy we will be doing the most common circuit bend the “tone bend” locate a resistor (usually close to the main IC) and change its value with something. You could put a light sensor there or a volume pot. Here I’m using an old volume pot and an on off switch to that pot. The end result is that I am adding resistance to this place in the circuit.
Here I have the alligator clips connected to the resistor a couple different ways for testing.
5.Mod the Case – basically drill any holes for parts and find how everything should fit before you solder anything in place.
6. Solder! – make sure you cut those wires the right length.
7. Button it up – finish up the job. you might have to do some more drilling to make everything fit, but as long as it can hold together then you are all good.
This is an ongoing project that I hope to end up with 15 to 20 circuit bent kids toys, that will eventually become a circuit bent orchestra that will all be controlled with Ableton Live. The keyboard in the video only has the drum section connected as of right now. Unfortunately it only has a polyphony of 2, so that limits me quiet a bit. I am using a sequencer I wrote in Pure Data running into an arduino board that controls some reed relays. The switch time of the relays is to long so I plan on changing them out with some solid state relays. The arduino is running standard firmata and I edited the Pduino program to include my sequencer. I have also wrote a patch that has Ableton control the arduino instead of my sequencer. Check out the video. Let me know if anyone wants to see the code.
