Default monophonic sequencer has one voice whose steps match .steps.

test_polyphonic_voices()

Polyphonic sequencer with N voices.

test_steps_is_voice_zero()

The .steps property is an alias for voices[0].steps.

test_voices_trait_synced()

The voices_data trait contains step lists for all voices.

test_set_step()
test_set_step_voice()

set_step with voice kwarg targets a specific voice.

test_set_step_out_of_bounds()
test_toggle_step()
test_toggle_step_voice()

toggle_step with voice kwarg targets a specific voice.

test_toggle_step_out_of_bounds()

test_add_track()
test_add_track_sets_sound_source_routing()

add_track sets session_id and channel_index on the sound source.

test_add_multiple_tracks()
test_bpm_sync()

Transport BPM propagates to all sequencers via traitlets.link.

test_play_sync()

Transport play state propagates to all sequencers.

test_remove_track()
