The Medeli MK401 Millenium Series Keyboard combines a standard 61-key playing layout with dynamic velocity control to deliver an authentic touch for learning players, music students, and desktop musicians.
Built around full-sized piano-style keys, it offers the physical response needed to build expressive finger technique and fluid control across a variety of musical styles. Combined with an extensive sound engine, interactive lesson tools, and versatile computer connectivity, the Millenium MK401 provides a comprehensive workstation for both structured practice and creative home production.
Touch-Sensitive Piano-Style Keys
At the centre of the keyboard is a 61-note keybed featuring touch-sensitive piano-shaped keys (PSTK). The velocity response mirrors the acoustic dynamics of a standard instrument, enabling subtle shifts in key pressure to produce natural volume variations and nuanced tone. This realistic action ensures developing players cultivate proper finger strength and dynamic control right from their first lesson.
Expansive Sound Engine and Accompaniment
Loaded with 450 instrument voices and 150 automated accompaniment styles, the Millenium MK401 lets users explore diverse genres ranging from traditional classical to modern electronic arrangements. A 32-note maximum polyphony maintains smooth note decay, while 10 onboard reverb presets add natural acoustic depth. Integrated pitch adjustments, including transpose, octave shift, and fine tuning, work alongside an onboard metronome adjustable from 5 to 320 BPM with tap tempo capability.
Dynamic Acoustic System & Audio Output
Onboard audio monitoring is delivered through two 12 cm speakers driven by an internal 2 x 2.5 W amplifier. An integrated Dynamic Acoustic System (D.A.S.) automatically optimizes the overall frequency spectrum relative to master volume levels, preserving clear bass response and crisp highs during quiet practice sessions. For uncoloured monitoring, the D.A.S. processing can be easily toggled off.
Lesson Functions and Digital Connectivity
Designed to support self-directed learning, the keyboard features an onboard Music Tutorial system paired with 120 built-in songs to guide skill development. A multi-function USB-B port provides combined USB MIDI and digital audio interface functionality, allowing simple recording directly into software on computers or mobile devices. A 3.5 mm (1/8") stereo headphone jack supports silent practice, while a dedicated 6.35 mm (1/4") sustain pedal jack accommodates standard expression pedals.
Power is supplied via the included 12V DC power adapter, or through 6 x AA batteries for complete mobility away from mains electricity.
