What is Chirp?

Turn your laptop keyboard into a MIDI keyboard controller. Capture musical inspiration on the go without having to lug along a hardware MIDI keyboard. Just use your laptop's keyboard or mouse to enter notes and chords in any music software requiring MIDI input or providing MIDI output. Use Chirp to audition soft synth patches in your favorite DAW or recording application. Want to write that masterpiece or work on that string part in your DAW during your cross-country flight? Chirp makes it both possible and easy. The keyboard is resizable on the user's display, and the computer key mappings are shown as labels on the piano keys and trigger pads/controls.

Chirp Detailed Information

Chirp turns your computer or laptop keyboard into a virtual MIDI keyboard controller with 18 piano keys, 10 drum triggers and all the control you'd expect from a piece of hardware. The program produces no actual "sound" itself - instead it produces MIDI notes and messages, which in turn "drive" any music software application, MIDI instrument or plug-in soft synthesizer capable of generating sound from MIDI input. Many music software applications and soft synths include some virtual keyboard capability, but very few allow the MIDI notes to be generated using your computer keyboard. Many limit input to a mouse click, which makes chord entry and real-time playing virtually impossible. Chirp accommodates up to 7 notes on the keyboard to be played simultaneously and in real-time, allowing for even complex 9/11/13 chord entry over 2 octaves.

Chirp was designed to be a low latency controller capable of both supply MIDI notes and displaying played notes from any music application with MIDI I/O capabilities. We envisioned the primary computer platform as a Windows or Mac laptop, and most likely in a remote environment where the use of a physical keyboard is impractical, such as an airplane seat, bus seat (or even your desk at work!) Chirp allows the user to choose which computer keys are mapped to the piano keyboard keys, as well as assign the trigger pads to any MIDI event.
