  • Two wavetable version changes on reset

  • Multiple invocations of AudioNode constructor - (?) Destroy on power off - (?) Make singleton

  • Power-on/power-off is resetting the plugs - [ ] Reinitialise OSC and LFO and redraw

  • Page transitions

  • Only redraw visible page

  • Use object.onload to cache radii

  • alt-click to use initial value

  • AA - [ ] alt-click: 24dB - [ ] include in settings

  • Restore settings - [ ] Make sure DD/wavetable also get initialised - [ ] LFOs start erratically - [ ] Optimise the controlsets restore - accumulate/set-all/clone-and-set ?

  • Restructure sn to generate an array of values - [ ] Optimize wavetable genfn for array - [ ] Use slice/shallow copy to map SAB to wavetable - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/slice - [ ] Reoptimise genfn - [ ] Commonalise parameters SAB - [ ] Commonalise DDS and wavetable

  • Load/overrun - [ ] Sort by level/onset and drop quiet/old notes - [ ] 'policy' settings - [ ] FN1: Use sine wave - [ ] Convert to Float32 throughout - [ ] Convert to TypedArrays throughout - [ ] Optimize envelope - [ ] Use frames rather than (potentially) erratic currentTime - [ ] Replace map/reduce with for loop - [ ] Update pre-allocated/static FloatArray

  • eventbus: publish in Promise

All The Other To Be Done Stuff

  • Rework eventbus using signals a la Motion Canvas

  • Initialise controlsets from HTML

  • Bar graph of note count and max note count

  • Format MIDI export data all nicely
