Someone searched on “sequencer different time grids” to find this blog. While I’ve been obsessed with different scale types, I never thought much about the implications of different time scales in grid sequencers.
Currently, this blog comes up second in the Google search.
The first hit is a discussion of an interesting-looking sequencer for Atari computers. Looks like a very early grid sequencer. Oddly, it’s a 17×24 grid. One of the 17 is “off” instead of just allowing no selection.
It looks like it’s evolved a bit and gotten less intuitive. But might still be fun to play with.
