C::NTR::L is a free, open source Human-Computer Interface for audiovisual live improvisation exploiting the physical computing technology. Developed in PureData by Marco Donnarumma aka The !S.A.D!.

C::NTR::L transforms your standard musical instrument - electric bass, guitar, violin, piano, trumpet, etc. - in an augmented instrument, an audiovideo controller without exploiting a specific external hardware or MIDI technology.

C::NTR::L is Plug&Play. Once you connected the instrument to the sound card of your computer, C::NTR::L  starts to recognize which notes you play. This is possible trought a complex structure of band pass/low pass/hi pass filters which automatically separate the core frequency of the incoming audio signal.

Then C::NTR::L analyzes the duration and the RMS of each single note and finally translates this data in order to control and trigger a set of audiovideo efx.
