Turn your QWERTY into a sensible music keyboard. Dependencies: gui/lib and rsound. Run: `racket program.rkt <root> <mode>` Where `root` is a musical note in all caps with `#` for sharps. And the mode is the mode 0-index, i.e. 0 is major scale while 5 is minor scale. There are eight columns on the keyboard that are used. For example the first column is the one made up of `1`, `q`, `a`, and `z`. Odd columns have four keys, while even columns have three (excluding the number). Every couple of columns make up 7 keys which make up the 7 keys of a diatonic scale. Therefore the first octave is accesible via 1,q,a,z,w,s,x While the second is accessible via 3,e,d,c,r,f,v etc...
