2RuleMidiSeq is a polyphonic arpeggiator and sequencer designed to transform chords into dynamic musical patterns. It automatically arranges the notes of pressed chords from the lowest to the highest pitch, generating complex polyphonic sequences that align with the beat grid. The interface features a circular note flow display, providing an engaging visual representation of the sequence in action.

Users can customize the playback with variable speeds, beats, velocities, and note durations for each chord note, allowing for expressive and intricate rhythmic patterns. The plugin supports octave adjustments for chord notes and accepts MIDI input from any controller, making it easy to create evolving sequences in real-time. Additional tools include a sync feature to keep sequences tight, a sequence matrix for pattern management, and randomization options to introduce creative variations.

2RuleMidiSeq also includes an integrated sine wave synthesizer for quick pattern audition without external instruments. It offers advanced velocity control options, including the ability to fix or use incoming MIDI velocity, enhancing dynamic expression. Users can choose between automatic note ordering or assigning incoming notes to the lowest available sequence line, giving flexibility in how sequences develop. This makes 2RuleMidiSeq a powerful tool for crafting lively and intricate polyphonic arpeggios and sequences.
