KORG FISA SUPREMA C (Buttons) - Compact 92-Button 120-Bass Chromatic Digital Accordion with T2L Motor and Built-in Speakers

The KORG FISA SUPREMA C Buttons version packs the experience of the standard SUPREMA into a lighter, more portable package, without sacrificing any of its power or expressiveness. It retains the sonic heart of the T2L (True-to-Life) system—developed in collaboration with Dexibell—and the latest-generation bellows response, but optimizes the cabinet and interface for everyday use: smaller built-in speakers , 12 physical switches with access to 14 registers , and a simplified right-hand keyboard (this Buttons version offers 92 velocity-sensitive buttons ; the Piano range uses 37 keys). The result is a mid-sized chromatic digital accordion , comfortable on stage or in the studio, with a wide, detailed sound and immediate handling.

Its architecture combines a maximum polyphony of 320 voices with 45 accordion types , dedicated organ sections with Virtual Tone Wheel technology (Upper / Lower / Pedal), Orchestra , Orchestra 2 / Soloist / Synth and a complete drum section . The effects engine includes reverb / delay / master EQ , two multi-effects per part , rotary , vibrato / chorus and organ overdrive . For modern integration, it adds Bluetooth A2DP (RX audio) and MIDI BLE 4.2 , plus 24-bit/48 kHz USB audio / MIDI and dedicated analog ports for treble, bass and headphones. The included rechargeable battery offers more than 9 hours of autonomy and the integrated speaker system delivers up to 70 W max. at THD + N < 0.1%.
