3.2. Arpeggiator Mode
The arpeggiator allows you to animate chords with ease. It includes 8 modes (up, down, inclusive, exclusive, 3 random modes, and note order). Use the 'Hold' function to sustain arpeggios while adjusting parameters. You can layer up to 4 octaves above or below for dynamic soundscapes.

3.3. Sequencer Mode
Experiment with intuitive step-sequencing or live recording. The sequencer supports ties and rests, and allows for appending or replacing notes at any point. It offers 64 steps with 8-note polyphony per step. Up to 8 sequences can be saved and switched on the fly. Adjust swing, gate time, and tempo subdivision during playback.
3.4. Chord Mode/Scale Quantization
The enhanced Chord mode transforms single notes into musical chords. Choose from multiple voicings, instrument-like strum effects, and velocity settings. Quantize notes to a list of standard or user-defined scales. The LED strip above the keyboard provides visual feedback, indicating which notes are allowed in the selected scale.

These knobs allow for real-time control over various parameters in your software or hardware instruments. Visual feedback LEDs above the keys indicate the sequence's progress and which notes are currently playing.
3.6. Tempo and Transport Controls
Dedicated buttons for play, stop, and record functions, along with tempo control, allow for easy management of your performance and sequencing.
3.7. Universal Connectivity
