The Casio PT100 In Circuit Bending 101: Getting More Out Of Your Synth

August 21, 2007
In this week's Circuit Bending 101, there are more ways to get sound out of a synth than just the keys

Circuit Bending 101 continues with this demonstration using a Casio PT100. Dan Demchuk works with Allison Lake to get unique sounds and bends from Allison's PT100.

To get more out of your synth, Dan and Allison go over maximizing space, exploring the synthesizer's possibilities, and installing switches. Stay tuned for more circuit bending tips and tricks at Gearwire.com.

The circuit bending workshop is a weekly event thrown by DJ Demchuk in Chicago.

synth plans

By: bholland
There's a lot underway here right now to expand that, and we're waiting for a bunch of synths to come into the studio. There should be some good in depth stuff coming soon.

circuit bending workshops

I'm no professional tech-head, I'm a DIY Circuit Bender. At Circuit Bending Workshops I offer people a chance to learn the bending basics free of charge and use that information to go where they may. The majority of workshop attendees have never done any electronics work in their lives. If you'd like more information on attending one yourself, visit going.com/circuitbend .

This whole series stinks. I know you've heard this before, but-yes-I have done better. Some advice you give is sillY--nooo it's lame.

I'm sorry but this video

By: Anonymous Coward
I'm sorry but this video seres is completely uninformative. The guy seems like a dumbass and says nothing a 5 year old couldn't guess about the topic. Chances are, if you vaguely know what circuit bending is then you've probably imagined that you take apart the device add switches etc. (which is pretty much all these lame videos mention, all while you have to listen to this nasal-voiced idiot who can't put a hat on straight let alone tell you anything helpful.)

Keep up the good work

By: Anonymous Coward (not verified)

I'm new to this, have just found a Casiotone on ebay and want to get started. These videos are great.
Unlike most muso forums where everyone's an expert (see previous posts...) your videos don't make that assumption.
Keep it up, I'm avidly watching.

This is a good soid introduction to circuit bending. Not too much technical BS to ruin the fun for nubies.

thank you

By: bholland

yes,

I keep meaning to do some serious bending on here, but haven't gotten around to it. However, we are sending a correspondent to Bent fest, so there will be more soon. I might show off my homemade circuit-bent vocoder that only cost me 75 cents to make.

Ah the PT100 - my very first

By: McMayhem (not verified)

Ah the PT100 - my very first bending project. If you need more room take the speaker out entirely and install a 1/4 inch jack. Pretty good bends on the PT, mostly distortions, but i did manage to find a frequency glitch that i wired to a linear pot to use as a pitch bender. Working on my CZ-101 right now. Good Luck

DAN DEMCHUK: Hi. I'm Dan Demchuk, again with the circuit bending workshop. Right now, I'm working with Allison Lake on one of her really cool Casio keyboards she found.

ALLISON LAKE: This is a PT-100. It's a fabulous Casio.

[ALLISON LAKE CIRCUIT BENDING ON A CASIO PT-100]

DAN DEMCHUK: She's really getting some amazing sounds and bends off this Casio keyboard, and what's really good about using a keyboard for live performances is that you can really create your own sounds. You know, having this synthesizer that you can control in so many different ways is really good for live performances. You know, a lot of people that do live PA are just using keyboards and making all kinds of beats with their laptops. Right now, you've got all kinds of unique sounds that not only have you made and found yourself but now you're playing too on the keyboard.

[ALLISON LAKE CIRCUIT BENDING ON A CASIO PT-100]

DAN DEMCHUK: She needs a lot of space to install her switches, so what you want to find is negative space on these things. Speakers tend to take up a lot of room, and the speakers themselves are acting out as resistors. This one here is marked. They're usually plainly marked. They're anywhere from 4-ohm to 58-ohm resistors that the speaker themselves are. Hers is a 4-ohm so we can always take that out, put it in a smaller one, and then we've got plenty of space now to add more switches and buttons to control all these amazing sounds she's getting.

After you find these points that make these sounds, you want to mark them with a Sharpie marker so that you don't lose track.

ALLISON LAKE: I like marking all the little hot sports and then later on finding the best glitches and drones and adding switches to them.

DAN DEMCHUK: Allison just said that she thinks that this is going to be a really good body contact. What you're going to want to do when you're adding those in basically just solder and wire to whatever points these are, and then run that wire out to anywhere from like a screw or even one of those cool metal spikes from like a spike bracelet back in the day. Install one of those, touch those two points on the outside, and you're going to get those body contact tones, and literally the possibilities are endless on these things.

Again I'm Dan Demchuk with Allison Lake here at the circuit bending workshop.

I need awesome gear... I'd like a free gear catalog!
My opinion is awesome. I'd like to take a gear survey
