Midify Operating Instructions

To configure Midify:

  • Hold down 5 keys that correspond to MIDI note numbers 48-52. The LED will start to blink quickly to let you know you are in configuration mode.
  • Press and release the key that corresponds to the config change you want to make. For example, note #58 would put Midify in poly mode. the LED will blink quickly a few times to acknowledge the command.
  • Release the 5 config keys. The LED will return to normal and your config change has been made.

To map keys:

  • Enter key assign mode by holding down the 5 config keys and pressing note #56. The LED will begin to double-flash slowly to indicate that you are in key assign mode.
  • Release the 5 config keys.
  • Do what you need to do to drive the desired output (now an input) “on”. If you are in active-low mode then you need to drive it low. For example, if Midify is installed in a GBA then simply hold down the GBA button you want to map. The LED will turn off to let you know that it sees the input.
  • Press and release the key on your keyboard you want to map the button to. The LED will blink a few times quickly to indicate that it has remapped the key.
  • When you are done remapping keys, press and release the 5 config keys to exit key assign mode.

A word about default key mappings

When it is shipped Midify is configured with the default 12-note key mapping. That means that MIDI note #60 controls output 1, #61 controls output 2, on up through output 12.

The other default mapping option is 8-note. This option starts at MIDI Note #60 and maps each white key to the first 8 outputs. The remaining 4 outputs are unmapped. This is useful for synth cartridges that only respond to one octave’s worth of natural notes.
