Sunday, April 24th Peter updated the code for single-note play. Multiple notes will play, but their amplitudes will be added without proper normalization, so there is distortion and intermodulation.
Monday April 25th Peter added a draft of a lesson plan on Binary encoding.
--------------------- NAME CHANGE EXPLANATION ---
Arduino (Processing) Development Environment requires the main source file name and directory name match, and also does not allow hyphens in sketch file names. Thus, it was necessary to change Alan's initial Repository/file from GHC-piano/piano.pde to GHC_piano/GHC_piano.pde
Now it is possible to say:
$ git clone email@example.com:splatspace/GHC_piano.git $ arduino ... and open the sketch "GHC_piano/GHC_piano.pde"
Authors: Peter Reintjes, Alan Dilpert

Goals: 12 binary inputs representng an arbitrary musical scale, multiple simultaneous notes, Variable attack decay, waveform modification for natural sounding tones.
Scale, range, dynamics, to be selected by creating a binary pattern under the reader and pressing the reset button. For example, nine of the twelve bits can be used to define the following parameters: Scale: Major, minor, harmonic minor, melodic minor (two bits) Fast/slow attack (one bit) Fast/slow decay (one bit) Zero, even, odd, all harmonics (sine,triangle,square,sawtooth) (two bits) Variable/Fixed Timbre (one bit) Variable/Fixed Amplitude (tremolo) (one bit) Variable/Fixed Frequency (vibrato) (one bit)
Current: 12 binary inputs representing the chromatic scale Four simultaneous sine waves (e.g. No dynamics or timbre)
