Got another circuit bent Speak on ebay, this time a Speak & Math. Check the demo. If anyone outside of the UK wants to buy it for £90, I'm happy to send it as long as they're on XLT. Thanks, Future Image |

how much would you charge me to bend my rolf harris stylophone. this isnt a joke btw. |

You can't I'm afraid. It's analog and with analog equipment you can't do much. The closest thing to a bend I've found is holding the stylus tip hard with one hand then touching the keys hard with the other. It makes some weird drones and stuff. The harder you hold, the higher the pitch. You could add filters and stuff to a Stylophone, but you can do those kinda sounds with a simple synth. |

stop breaking innocent toys! just because you hate math don't mean you gotta "get back" at the math toys! what's next? circut bend a Speak and Girls? |

actually, you could do a hell of a lot with a stylophone... you just have to know a couple of things about electronics and not just mess around with a soldering iron and randomly adding wires and crap. You could add a TL074 and make a nice sallen-key low pass filter with resonance, or add a distortion/clipper stage or whatnot. I'd rather have a stylophone than a digital toy, all you can do with digital is glitches, unless you really know what you are doing and get down to bit bashing. |

"You could add a TL074 and make a nice sallen-key low pass filter with resonance, or add a distortion/clipper stage or whatnot. " But surely you can do exactly the same with a freeware softsynth? |

awesome.tho i know fuck all about electrics,or anything for that matter. |

see i should of said electronics. *hanal gets his coat* |

no a freeware softsynth requires a computer and mouse and all that crap. my idea needs 1chip, a few resistors and capacitors and two knobs. Also a label marked cutoff and resonance if you're really fancy! I thought the whole idea was to get away from computers. I can get a glitch VST, timestrech, looping, etc on a computer, so why should I spend £90 on your ebay thing? |

ok i pimped mine. version 1,sounds just like the original. |

version 2,tastes better than the original. |

The Glitch VST won't make all the sounds itself, will it? It just effects the input. What I'm selling makes sounds that are hard to create elsewhere. |

Do you have schematic of that? I might use that in my |

A glitch vst might not make all the sounds itself. But try messing with maxmsp, it will. Personally, I love the idea of curcuit bending anything (not that I've done much myself), particularly analogue synths, since you can do plenty with some passive elements, and maybe a few opamps or something. Its all experimentation. |

haaahah! |

Mind I don't really call the analog stuff bending, more modifying. |

Ok, quite lazy, but you should be able to fill in the gaps: http://en.wikipedia.org/wiki/Sallen_Key_filter gives idea about sallen-key filters. make the caps and resistors the same value to make the equation for cutoff frequency Fc=1/(2*pi*R*C). now make the two resistors variable resistors, by using a dual-gang potentiometer.(this is cutoff freq control) For resonance take the output of the filter, through a non-inverting opamp amplifier back to the input, and set the gain to above unity. Put a potentiometer (variable resistor) between the output of this amp and the input of the filter stage, so that one end of the resistor conencts to 0V and the other to the amp output. The wiper selects the amount of feedback from 0V to the amp output voltage. (this is resonance control) For distortion, a nice trick is to do an inverting opamp amplifier and use an two LEDs connected in inverse parallel as part of the feedback network to clip the signal nicely.... so you have the input resistor, then from the output terminal to the inverting input you have the feedback resistor. Now connect a LED in PARALLEL to the feedback resistor, then connect a second LED in PARALLEL again, but the opposite way round and there you go. Links to wikipedia to help out. http://en.wikipedia.org/wiki/Sallen_Key_filter http://en.wikipedia.org/wiki/Operational_amplifier_applicat ions#Non-inverting_amplifier http://en.wikipedia.org/wiki/Operational_amplifier_applicat ions#Inverting_amplifier Hope that kinda makes sense. If you want more help tell me your email and I can send you a mail with diagrams,etc if that is easier. I hope you have fun with electronics, but I hope you do less random wiring and more thought-out stuff, the benefits are huge. Instead of being able to offer 120 different types of glitch, you can add marvels like a mic input to set the filter frequency to level of your voice (hello fenixfunk10) or other such fun things. maybe a visit to http://www.paia.com/ would be of interest. above all, I hope you e |

stupid character count.... just wanted to say I hope you enjoy yourself. P.S. for the sallen-key ignore the other equations, just worry about the Fc=..... one. that gives you the cutoff frequency in hertz. good luck |

Well, I am kinda working with Synth DIY aswell, mind I guess my creations so far have been more luck based (the Black Box linked earlier was me rewiring a flashing LED circuit) so.... I'll try a few of the Wiki schematics and spend some time tomorrow working those equations out. I'm taking GCSE (and maybe A-Level) electronics mainly to learn more about these equations, etc. Thanks a lot. |

Yep, I give up. Just spent about 30 minutes trying to work out a schematic and I've got pretty much nowhere. My email is futureimage@hotmail.co.uk so feel free to send any schemats there if you've got time to. Thanks a shitload. |

The thing went for £26. The last bent Speak went for £66 and had fewer bends. Shit. |
