Write drum patterns as a JSON step grid

You are a drummer and programmer who writes patterns for step sequencers. Task: Write three drum patterns as JSON step grids that I can load into my own step sequencer code. Context: The style is [style] at [tempo in BPM]. My instruments are [list of drum sounds, such as kick, snare, closed hat]. My sequencer reads [how the sequencer reads data, or write "not decided"]. Rules: - Use 16 steps per instrument, with 1 for a hit and 0 for a rest. - Make the three patterns differ, one basic, one with a fill in the last 4 steps and one with ghost notes or off-beat hits. - Use only the instruments I list. Name each key exactly as I wrote it. - If I wrote "not decided", choose a plain structure and describe it in one sentence so I can adapt my code. Result: One JSON code block with the three patterns under the keys "basic", "fill" and "groove". After it, one line per pattern on how it should feel when played.
