Simple bends for the casio vl-tone

1. How to circuit bend a CASIO VL-TONE Circitfied http://www.youtube.com/user/circitfied?feature=mhee

2. Health & Safety ALWAYS USE BATTERIES WHEN CIRCUIT BENDING! Do not plug the keyboard into the mains when the case is open. Be careful when using sharp blades. Wear safety glasses when drilling holes. Solder in a ventilated area. If you are unsure about anything you are doing ask a professional. Its not my fault if you injure yourself or destroy your keyboard.

3. Tool List Soldering iron & solder Screwdrivers Pliers Wire strippers Wire cutters Drill bits Drill Solder sucker Ruler and marker pen

4. Component List 7 x variable resistors (pots) 100KΩ + 7 x nobs to fit pots 6 x single pole single throw switches (spst) ¼” mono socket with break contacts An enclosure to house the switches, I use mini-trunking Miniature wire Screws

6. First Bend Attach a wire to the positive on the battery. Touch the other end to pin 2 on LA6355. You should here something interesting.

7. Second Bend Attach a wire to ground (negative) and the resistor below C221.

9. Master Tempo/Pitch Bend To carry out this bend you will need to get to the board with the keys and master chip on. Be careful, otherwise you may stop the LCD from working. Cut out the 56KΩ Resistor. Solder a pot across the junction.

10. More Pitch Bends You can cut these off and use your own pots mounted on your enclosure, allowing you to crash the circuit, great for dubstep, or speed it up the tempo for some great speedcore.

11. Enclosure As the Casio is 300mm long it gives you loads of room to mount everything externally. I prefer mini trunking, it’s just wide enough for all the pots.

12. Line Out  Jack Out The line out is labelled on the circuit board. Use the solder sucker and soldering iron to remove the line out. Solder on some wires and then solder the ends to the ¼” socket. It may take some trial and error to get the right connections. Then try with some headphones to see if it works.

13. Soldering A Potentiometer In my Casio I have used a switch and a variable resistor (potentiometer). If you want to save money you can just use a pot or a switch with a resistor. 1)To wire up, solder a wire to one side of the switch. 2) Then from the other lug on the switch solder this to the middle terminal on the pot. 3) Solder another wire to another lug on the pot. 4) Solder loose wires to the circuit board.

14. More bends There are a lot more bends on this Casio. It takes perseverance. Wet your fingers and run them across the circuit board, alternatively use a bare wire, or your tongue! Press buttons at the same time or push the melody button. If the keyboard crashes turn it on and off. If it still seems a bit ill take out the batteries and reinsert them after 30 seconds.

15. ENJOY!
