Drew: Here are my part search notes, May 2008. (Note, I think analog mux plus on-board ADC's might be a better option) Digikey, in-stock search, Package with 64-128 pins, reveals three ADC…
This design is for two digital switches per key. 2 Arduino outputs - 4 bit Binary Counter - 4 to 16 Decoder (really a couple 3 by 8's ) - 16 x 11 diode matrix - 11 Arduino inputs. Leaving one pin…
Some Fatar Keybeds have used a conducting spring that can come into contact with two conducting rails as a keyswitch. Since the spring is used as an electrical contact, it is advantageous to…

The action of the keybed is what provides the mechanical interface between the musician's fingers and the keyboard. At one extreme the action could be as simple as a momentary pushbutton switch. At…
The actual arrangement of the keys can have a significant impact on how difficult it is to learn to play a keyboard instrument, and what musical styles are possible even for those skilled at the…
The key scanning circuit provides the electronic interface between the key switches and the micro-controller. Digital keyboards have many key switches. At least 88*2 are required for a velocity…
Key switches provide the interface between the mechanical and the electrical portions of the piano. Rubber Membrane Keyswitches The vast majority of commercial keyboards use rubber membrane…
Key Designs DIY Keyboard keychain This keychain was generated from Rhinoscript code that is stored in the repository. The key is defined parametrically, so parameters like the keychain height and…
This page posted by Drew Wagner One way in which most digital pianos are thoroughly deficient compared to their analog counterparts is in the quality of the pedals provided. For example, for the P85,…
