I am curently in college and as a project i am proposing to create a sound installation. The plan is to use piezo sensors that detect movement
and these sensors will communicate with ableton to trigger a clip/piece of music. Am a total novice and have been reading some of the posts. Do i need to use a Arduino board to bridge between sensors and ableton? im using max for live within ableton.
Also can anyone direct me to a patch thats needed? i really need some help on this and any help is gratefully appreciated
Thanks
Shane

For whatever type of sensor you want to use you’ll need some kind of ADC (analog to digital converter). The Arduino is a very cheap and easy to use version of this. You can also use Maxuino and do all your programming straight in Max (without having to touch/write Arduino code).

within Ableton. i never heard of Maxuino but im going to look into it. My question is how exactly do i get these sensors connected to the
board and connected to Ableton? i have Ableton suite 8 with max for live.
Thanks

Still not sure what you mean on the physical side of things. Like you want a couple piezos attached to the floor in a room, and people walking will trigger it?

When
someone walks or steps on the sensor this will trigger a clip in ableton lets say a loop. and lets say someone else walks into the room and
stands over another sensor, another clip will play. if 5 people are in the room and stand on sensors 5 clips will play and so forth. i just want the sensors to trigger the midi clips and when the person steps off the sensors the clip ends.

I used some Yamaha and Alesis modules, and it was always rock-stable system. Moreover old MIDI drum modules are not expensive (if you have a luck…).
