Hi there,
i've been searching the internet for several days now, to build a ultra-compact midi controller. Doepfer in Germany produces a similar product to Midisense, but the controlling software is less adjusted to calibrate resistors and the price is fairly high (starting with 75 euro, 100 USD).
MidiSense seems to be what i am looking for, i just wonder what the difference in implementation is between the analog board that is not yet released and the resistive sensor board. A sensor is just another type of potentiometer, isn't it?
Anway, i want to implement a touchpad or multiple touch-sliders into a small controller. A midi signal should only be send when the device is touched or released.
Is the actual board enough for me, or is it better to wait? Do you have an eta when the new board is ready?
resistive sensor versus potentiometer analog board

thanks for your quick reply!
I was thinking of using one of these: http://www.voti.nl/shop/p/S-Touchpad.html for example. It is just an ordinary pc/laptop pad with the ps/2 connector cut off. If it doesnt work, a direct connection to the pad. (I guess it has 2x2 wires leading there?)
Alternatively, i was thinking of opening an old/broken korg kaoss pad with a working touchscreen.

hmm according to this datasheet http://www.voti.nl/docs/touchpad.pdf and this website http://instruct1.cit.cornell.edu/course ... chpad.html
it seems there is only a ps/2 signal going out... which probably doesnt work too well... hmm

this looks like a REALLY nice solution http://www.spectrasymbol.com/linearposition.html . It's a bit like the qslide, but just a pure resistor as far as i can see without a controlling ic. Seems like a great solution for the analog input board to me, its just that i need to find a retailer... I requested a sample from the site, hope they can send me a resistor to test it. I will keep you all informed.
