Graphic Waveform Generator Model 268e

traffkin · Post by **traffkin** » Fri May 18, 2018 6:17 am

We here at Keen Association, are very proud again to introduce our Graphic Waveform Generator Model 268e, the module we've been designing, experimenting with and improving during last two years.

The main idea is a virtual tape upon which any waveform is drawable, by hand or automatically. Possible everlasting phase-shifting makes the sound vivid and mercurial.

268e is a quad system so the user gets four oscillators, freely configurable. We started to design it as a compliment to our Model 220 but later realised that it fits perfectly in any controller paradigm.

the run is 20 units, as usual

people who interested, please pm me

Hey !

looks fantastic.

any idea of price yet ?

Does it work with the 200e preset manager?

Yes it does work with the 200e preset manager.

been repeating to myself "must. not. start. a. modular."
this looks really cool

You've been repeating that since 2011?

yes it does

I have been blessed with the gift of willpower. Which has been slowly decreasing the more I visit threads like these...

Looks great. Really cool that it responds to the preset manager.

Can the pitch of the 4 oscillators be addressed by a 225e over the 4 channels of the 200e internal bus?

no, sorry, we prefer analog patching

but in some future, who knows...

I think the "Drawing" your own waves is cool,
but is there an easy way to call up SINE, SAW, etc?

traffkin · Post by **traffkin** » Sun May 20, 2018 5:35 pm

isn’t there quite a lot such oscillators with such capabilities?

ONLY ABOUT A MILLION!

well, speaking seriously, there'll be "reset to sine" feature in a while, pretty useful for various modulation stuff

I remember reading some things like ten years ago about something called "scanned synthesis" but didn't see much on it after that.
Is that what this is based on? It seems similar, and really cool!

traffkin · Post by **traffkin** » Mon May 21, 2018 3:16 am

i have not read anything on that but it is interesting, will try to find the info.
my idea derived solely from the cardiographic tape i watched once upon a time several years ago

Here's a paper on it:
https://pdfs.semanticscholar.org/61f4/4 ... c7b45a.pdf

Quite interesting and apparently similar. They use a physical model of a string to generate the wave shape and let the performer manipulate the string in various ways to change the timbre. This quote near the end is perhaps relevant:

Since the scanning process is independent of the computation of the string shape, it is possible to stop modifying the string shape (freeze the string) but continue scanning and hearing the now unvarying spectrum. The effect is dramatic. Within seconds after the string is frozen, the timbre becomes dull and uninteresting.

I seem to recall there was a Eurorack module a few months ago that claimed to use a variant on scanned synthesis, but certainly nothing so visual as the Keen module.

thanks, i'll have a look!

similar but not the same definitely, i don't have a buffer and can't scan anything out of what is on the screen which is not literally scanned but just played back. when the "tape" stopped the spectrum and phase gets frozen otherwise there's permanents phase shifting. but the idea in the paper is very interesting and promising! thanks again

I’ve just installed mine tonight and got some rich sounds out of it. I still don’t fully understand the device and will dive into the menu this weekend.

Classy and well-thought-out product, Alex

it is not too much in the menu yet but it will grow

Right you are. Menu is simple. Oscillator is complex and rich. Wow! Such an interesting & novel addition to the 200e. See/listen below.
