exactly, on my definitive midibox
i will tinned the pads 
and varnish each pad with a varnished conducting.
here is my testing board, if it’s help !? (10x15cmx300dpi)
the circle is approximatively 9cm.

NOW ITS ALL CLEAR
;D ;D ;D
NICE WORK !!
would be great to see it when its done !
Salut mec!
When i saw your cool Camambert board it struck me: THE ULTIMATE REASON REX TRAVELLER! ;D
this circular trigger pad is going to revolutionize my musik making too, i’ll use it to trigger REX slices in any way or order i want.
I etched a quick board to play with,
but I have the very same problems as you describe:
Notes seem monophonic and are quite noisy too.
how did you fix it in the end? thanks in advance, Alex
ok good question !
and i have the solution 
excuse my english, if u don’t understand something
it’s surely because of my expression, but i try.
1- the first problem i have encountered is when i touch a sensor
the message 0,127,0,127,0,127… was send in loop
to resolve this problem i have simply connect the 0v of the midibox
to the ground.
2- ok at this stade, when i touch a sensor it send correctly the values
like a button. (but very quickly and intuitively)
but when i touch to or more sensors, there’s no more message send
or messages are send randomely.
to fix this problem, i simply plug myself ;D
with a jack in the belt directly to my skin
connected to the ground ;D
Now my body was perfectly at 0v, the computer
& the midibox also !! and i can touch 32 or more
sensors, without any problem, like a button.
i search a better way to solve this problem, but for now
i plug (myself) & play ;D
Now i’m on way to design my definitive midibox
with two circular “camembert” of 7 & 9 parts
and some linear touchsensors of 12 parts… 8)
From where come this purple colour of your board ? ???
HI!
ok, thanks for the info!
I guess i’ll stick a JACK up my nose from now on ;D
The board looks purple because I took the foto with my mobile phone…
Have fun!
Alex
ooh yes neo-lo-fi picture !! 8)
yes stick the jack in your nose
and ready to play :-*
Bionic synth implants!
6 million dollar man?
Maybe 6 Million hertz man ;D
any idea if it’s possible to use this kind of design for a fader/pot, or is that just not possible. another idea is to take the legth of the fader and making 127 little pads and somehow getting mios to recognise it as 1 fader/pot.
i think is impossible, but don’t know
for sure 127 sensors, are not easy to build
and a linear slider, it’s surely a better way..
Would be easy to have a detented encoder send info depending on it’s position. However many pads you wanted would be how many detents you’d need on the encoder. Using a nice big jogwheel style knob would probably have the desired effect. Just a bit of MIOS code to write.
