Literal [monome web]:
the monome 40h is a reconfigurable grid of sixty-four backlit buttons.

buttons can be configured as toggles, radio groupings, sliders, or organized into more sophisticated systems to monitor and trigger sample playback positions, stream 1-bit video, interact with dynamic physical models, and play games. button press and visual indication are decoupled by design: the correlation is established by each application.

applications span all forms of media and data. the 40h uses usb and talks serial, midi, and open sound control.

all software and firmware is open source. we aim to facilitate a community of shared exploration.
