Create polyphonic chord generator

[oubiwann]

Go full music theory, more so than the other VCV Rack chord plugins.

Tasks:

• Design layout
  • trigger input
  • knob for trigger, trigger + hold (2 values) + CV input
  • knob for duration (multiplier of clock: 1/32, 1/16, 1/8, 1/4, 1/2, 1, 2, 4, 8, 16, 32, 64 - 12 values) + CV input
  • knob for tonic (ordered as circle of fifths - 12 values) + CV input
  • one or more knobs for roman numeral support?
  • knob for inversion (root, 1st, 2nd - 3 values) + CV input
  • selector for chord type (triad, 7th, 9th, 11th, 13th chords - 5 values) + CV input
  • knob for triad (maj, min, aug, dim, sus2, sus4)
  • knob for 7th (maj, dom, min, dim, minb5, m/maj, maj#5, aug, dim/maj, b5, majb5 - 11 values) + CV input
  • knob for 9th (maj, dom, dom/min, min - 4 values) + CV input
  • knob for 11th (maj, dom, min, sus, b5, b9, Select random input #9 - 7 valyes) + CV input
  • knob for 13th (maj, dom, min, sus, b5, b9, Select random input #9, b11, Create a better chord progression #11 - 9 values) + CV input
  • knob for adds (2, 4, b9, 9, Select random input #9, b11, 11, Create a better chord progression #11, b13, 13, Support safe async looping #13 - 11 values) + CV input
  • knob for drops (1, 3, 5, 1+3, 1+5, 3+5 - 6 values) + CV input
• Add sequence support
  • provide a row of buttons (16?) at the bottom, each supporting a new "screen" with its own settings
  • each button should have a light above it, on when enabled
  • each "screen" should have an "enable" switch
  • at the end of the row of buttons, have a register switch (12 values), essentially a sequence multiplier
• Define light color meanings:
  • red - active, currently being played
  • yellow - active, not being played
  • off - inactive
• Implement code for all of the above ...
