troubleshooting

If you get an ‘error: init’ on load, then make sure you have a Grid plugged in. The script doesn’t function without one. If you have a Grid plugged in and you’re still seeing this error then post below with details of what Grid you’re using and how it’s connected to your Norns.

Version history

v1.7

Added MIDI output. It works just like regular output, except that moving along the up/down axis of an attached grid no longer changes filter cutoff. Instead it changes the MIDI note length. Near the top you get plucky 0.01-second notes, at the bottom you get sustained 3-second notes. You can customise this by editing the midilengths table near the top of gridofpoints.lua.

v1.6

add “magic mode” where random notes are played over time. To engage and disengage, press the four corners of the grid at the same time. The pace of forgetting past notes has also been slowed.

v1.5

gridofpoints now checks if a grid is connected and displays an error message if not

v1.4

button-press memories now fade with time, rather than with action (pressing keys)

v1.3

gridofpoints remembers which keys you pressed, though memories fade

v1.2

Fixing inverted Crow outputs 3/4 Added support for grids that aren’t 16x8

v1.1

Reversed x/y mappings on grid, and output one and two on Crow Also added a faint echo on grid of the last note you pressed, so it’s easier to remember where you were

v1.0
