A melodic step sequencer: draw a line on a pitch grid, and Linestep plays it as MIDI notes in time with the clock. It makes no sound itself, so connect it to any instrument.
The idea
Pitch runs up the grid, time runs across one measure, and a piano keyboard along the edge shows which row is which note. You can paint notes by dragging, set each note's velocity, record from a MIDI keyboard, or let one of two generators write a line for you, then edit the result like anything you drew.
Nothing you draw is thrown away by a setting change. In Monophonic mode, a column with several notes plays only the most recently drawn one and shows the others in grey; switch to Polyphonic and they all sound again. Division works the same way: the pattern keeps detail down to 1/32 notes, so choosing a coarser view hides fine notes without deleting them.
