Medeli AK603 Digital Workstation – 61 Touch-Sensitive Keys and 750 Sounds

The Medeli AK603 from the Arranger Pro Series is a professional digital workstation that offers serious musicians an impressive blend of power, versatility, and ease of use. Inspired by the flagship AKX10 , the AK603 offers many of the same high-quality features in a more compact and accessible format. The keyboard features 61 velocity-sensitive PTK II keys with professional response, an exclusive German Grand piano sound, and a powerful speaker array (2 x 25 + 2 x 15 watts) that guarantees a rich and dynamic sound.

With 750 tones, 280 accompaniment styles, 256-voice polyphony, and a comprehensive effects suite (including compressor, reverb, chorus, and master EQ), the AK603 is ready for any genre. Creative features like the Phrase Pad, Break, arpeggiator, harmonizer, and extensive Performance memory (6 x 32 banks) offer maximum expression during live performances or studio recording. Thanks to USB-MIDI/audio, audio recording and playback (MP3/WAV), a built-in 16-track sequencer, and compatibility with GrandSuite editing software, this workstation is fully equipped for modern music production.
