Heya all,

What is the Xth Sense?
"is a biophysical musical instrument. You can build your own and produce music with it using the sound of your muscles.
It is free and open source, and it was named the “world’s most innovative new musical instrument” by the Georgia Tech Center for Music Technology (US, 2012). Its name is spelled ecsth sense (not tenth sense!). But it’s way easier to call XS."

The Xth Sense (software and hardware) is finally available on-line, get binaries, DIY documentation, and tutorials at:
http://res.marcodonnarumma.com/projects/xth-sense/

The digital interface is developed in Pd; there's a main software for the computation of incoming muscle sound (and virtually any sound input), and the xth-sense-lib, a collection of 120 objects (and help files) ranging from specific muscle sound methods, to everyday Pd patching needs. It also includes a lot of GUI stuff, to facilitate building things.
Wanna the source? Here you go: https://github.com/marcodsad

With the XS you can also control other software on your machine (video, audio, light systems, etc.), send Voltage output to hardware, or control a prosthetic arm.
Hacks are encouraged by the design of the instrument itself. For some ideas see:

We have a (newly born) user's forum, courtesy of Create Digital Music/Motion; the forum lives at:

We are on also on Facebook (imagine!):

if anybody works with it, let me know!
We have users and works in Australia, Sweden, US, UK, Ireland, Spain, Vietnam, Germany, Russia, Netherlands, and Italy, so far

hope it is useful to some of you,
cheers,

hey!

[line3] is in /extra/flatspace if you're using pd-extended 42.5 it should be there.
Or are you using another version?

as for the 80Hz, is it coming from the sensor hardware, or you are using the software only?

hey,
sorry for the bad explanation of the problem... too excited to try out Xth Sense.

The line3 issue is on lubuntu (12.04) pd version 0.43.1
No flatspace in my extra folder (??)

The 80hz sine wave issue is related to the [efx.pshift.ssb~ 80] object.
When I connect this object to the output the sound starts (80 hz or the inlet freq) it doesn't just trigger the input signal, it always keeps going on
On windows (pd 43) a lot of error messages but it seems something is working too. (I know it's not for windows but I had to try). Here I have flatspace lib so no line3 error.
[efx.pshift.ssb~ 80] issue is similar but I quite solved it reducing the incoming gain... (still studying the matter on linux)
I'm using some external mics (electrect, piezo) I didn't create the silicone part yet.

I tryed gui.delay and gui.bubbler fx so far but it will be a very long study...
cheers

no worries, happy about the excitement

re: line3, the fact that flatspace is in pd-ext 43 on windows, but not on Linux, is indeed a bit weird.
Unfortunately, I don't have a machine with pd-ext 43 at the moment. Should get one soon to test dependencies myself. I remember using one in Berlin though, and there was no problem.

On Linux, can you type in a shell:

locate line3.pd

and post the output (if any)?

re pitchshifting: the object itself does not produce any sound, only processes it.
This means the noise is coming from your input. This could depend on a variety of element: your soundcard input, a too high gain, etc.

Be aware that the system is designed to work with the mic model which is indicated in the Xth Sense parts list. If you use any other mic, I can't guarantee it will work as it should. The silicon case is critical too.
Also, you don't want to use a piezo mic with the Xth Sense, unless you're purposely trying to use piezo.

let me know,
cheers!

no reply for locate line3 in xterminal
I manually searched in /usr/lib/pd-extended/extra/ too but no flatspace... dunno why...

I believe there was discussion a while ago about getting rid of flatspace because it just consisted of objects in other libraries and was, therefore, redundant. After looking around it looks like [line3] is part of the nusmuk library, but I don't see that in my Pd-extended 0.43 install, either.

The nusmuk sources are here if you want to try and compile:

http://pure-data.svn.sourceforge.net/viewvc/pure-data/branches/pd-extended/0.42/externals/nusmuk/

alright, thanks for the useful info guys.
Well, at this point I'll code a similar object and include it in the xth-sense-lib asap.

will keep you posted.

meanwhile, attached [line3] binary for Linux (working on Lucid 10.04)

Yop,

very interresting. Is it very sensible to ambient audio loudness ?
I imagine the quality of the silicon (or whatever material) will matter...

Is it reasonable to think about using in a very noisy environment ?
Won't my muscles resonate with the bass kicks ?

Thank you very much,

Nau

hey Nau,

the software comes with filtering and thresholding designed to avoid any feedback and sounds from the outside. If the silicon case is well pressed against the skin, you won't have any problem.

I usually play in the middle of a quadraphonic or octophonic system, and recently started playing along with a friend drummer (with a traditional drum and live electronics) and it works well.

Thank you for these good news !
