Anyone know how to control KAOSSILATOR via Breadboad Wiring?

[metamorphfly]

Does anyone know how to take a KAOSSILATOR apart so that it can be controlled via a breadboard and voltage?

I'm referring ONLY to the following:

1. Program Change
2. One of 3 areas pressed
3. And the pressure level for each.

don't think the kaossilator responds to pressure, so i'm not sure what #3 means?

for touchscreen hacking i suggest this page

program change is just a rotary encoder so you can probably just send a pulse to the proper place.

Thanks man.

It definitely responds to pressure, I've been using it for about a year many times a week and it responds to at least 2 levels of pressure (perhaps its view of aftertouch on keys).

And of course 2 fingers, it does some kind of differential.

Same with 3, some kind of differential possibly triangluar.

4 fingers doesn't matter.

What should I do with my KAOSS Pad now?

Not only is it just a year old, but the power input is loose in the back and just shuts off randomly.

Plus, it seems it's nearly worthless compared to the KP Pro.

Maybe get it repaired under warranty and sell it on eBay?

I don't know. Do you have a page on controlling it's surface?

Then because it's outdated it would be worth the risk of taking it a apart and doing a breadboard with it first.

Couldn't find anything.

I'm of course familiar with the arduino duemilanove and the MAKE Controller kit through my work with Cycling '74 products, but nothing showed up for KORG even in the search or KAOSSILATOR.

Most website search engines don't even work.

Got any other references? Thanks in advance.

sorry but you're wrong.
it does NOT have a pressure sensor - just like the kpro does not respond to velocity, neither does the original kaossilator.
how many fingers you're touching the screen with has absolutely nothing to do with pressure.

frankly i think the kpro is essentially worthless. not sure what about it makes the kaoss pad obsolete since they do completely different things. i think 10-15 years down the road the kp3 will be a classic, and the kpro will be more or less forgotten.

you're not going to find a simple page with how-to instructions made for a kaossilator if that's what you're hoping for. there are a few ways to circuit bend a kaossilator that i can point you towards but they are not the same as what you're looking for.

best to understand how the screen works and use that knowledge to hack in what you want. the touch screen carries the x-y coords on two of the wires, you could send data from your arduino to those points instead.

Not only is it just a year old, but the power input is loose in the back and just shuts off randomly.

If you're talking about using a power supply - use rechargable batteries instead.

kaoss pads don't take batteries?
unless he's talking about the kaossilator?

It doesn't take batteries.

Just the KORG AC Adaptor DC12V.

It's not the Adapter that's the problem.

It's that little two-prong insert that basically shuts off unless it is pushed a little to the right or left. Basically not a tight coupling.

This is my only Major Complaint about the unit other than being outdated so quickly (at least for my purchase).

The KAOSCILLATOR I have not complaints about whatsoever.

But the fact that it's not integrated into the KP Pro really irks me because that's atomic for stage performance.

If you're talking about an original Kaoss Pad, i.e. a "KP1", then yes, of course it's outdated.
I agree with Mr. Anagram in that the KP3 and KPro are very different devices and even that the KP3 will be a classic in time. Although I do not agree that is worthless. Aside from using Ableton, there's only the Electro Harmonix 2880 looper that has the same (similar) looping capabilities as the KPro. As a "synth", it's only really an improvement on the original because it has twice the number of sounds. I do agree that it won't be a classic like the Kaoss Pads but at the moment it seems to be the only hardware looper in its class. Correct me if I'm wrong anyone.

To the OP, I suggest getting a new adapter or fixing the problem another way and using the Kaoss Pad to its potential. Whichever one it is, it can still be used to very good effect. No pun intended.

Well, a few things are clear,

1. It does have Programs L.00 - P.99

2. Each program deals with X and Y access a little differently.

3. Most use it for Note on the X axis, though others for various DSP effects for Patterns in P.XX

4. Most use it for another DSP effect, some times 2 depending on which region you're in for the Y Axis.

5. Obviously you can use 1, 2 or 3 fingers to define the placement of where the contact point is, it appears to just calculate this linearly for 2 points, and for 3 probably angle bisection of a triangle.

6. When it comes to PRESSURE SENSOR. All I can do is go from observation, perhaps as one presses a finger down, it expands the surface area of your finger point into corresponding sides of the aimed point - that would be a perceived effect of pressure.

Either way my Goal is the same. I'd like to be able to control, using the Arduino, a safe voltage going into the "2 Wires" mentioned (If anybody has a photo of the Board and can indicate to me which are the 2 wires I'd appreciate it.

One way I suppose to find out the safe voltage ranges, is to use a DC voltage meter. Anybody have any links to a low-cost one for small units like this?

I'm not concerned about Program Name, Scale or Gate Arpeggio at this point, though it would be nice to know.

Here is a complete KMOD kit that includes schematics etc.

But I am only interested in controlling the X-Y touch point.

Does anybody have a part name or URL that provides an Arduino protoshield pluggable mini-din connector...essentially you would have to intercept the mini-din 6 and then pass it on.

But which wires and which voltages to apply to begin a sound on any of the specified X and Y ranges...I'm unsure of.

For the Arduino, I imagine if these are ranges in voltages I can map the ranges to a list of enumerations using the built in, I believe it's the vector function.

Thanks in advance for any tips.

look, seriously, no offense, but there is not a pressure sensor. there just isn't. it has a touch sensor, they're different things.

you're going to have to do some trial and error to achieve what you want, and you'll probably have more luck getting help on an electronics hobbyists forum.... i'd help you if i still had a kaossilator and some time on my hands.

but there should be 4 wires coming off the touchpad, one of them will be positive voltage, and one will be ground. the other 2 will be what you want. you're simply going to have to have a poke around in there and see which is which.

i'm more of a circuit bender/hacker than an knowledgeable electronics nerd, so i can't help you much.

most digital devices have an internal voltage of either 3.3V or 5V.
