Storing a large multidimensional array of booleans for the grids was quick and easy but

  • 3 channels
  • 3 layers
  • 16 quarter notes
  • 24 pulses per quarter note

multiplied out to 3,456 bits which is more than the 2048 (2KiB) of RAM available on the ATMega328.

Thankfully there are 1024 8-bit bytes of EEPROM and the grids needs to be stored anyway, but that will also slow things down. Fix all these at once.

#7 Grid now operates as 1 EEPROM byte per step

...though now the module is acting as though it has died!

#7 excellent progress on weights

reading and writing are working again. Apparently, don't use uint8_t on for loop iterators! Now cleaning up some data corruption.
