Critic Reviews

Casio CT-6000 Keyboard (1984) | Wolf Review

wolfarchitects.design

The Casio CT-6000 exudes a nostalgic charm with its sturdy build and vibrant aesthetics, reminiscent of professional synthesizers from its era. The inclusion of MIDI and velocity-sensitive keys was groundbreaking for 1984, appealing to semi-professionals seeking more than a typical keyboard. However, its design isn't without flaws; the mismatched materials and awkwardly placed speakers detract from its otherwise classy appearance. Membrane switches, though visually appealing, can be cumbersome. Collectors will find its rarity and potential value increase enticing, especially when complete with original accessories. Despite its quirks, the CT-6000 remains a desirable piece for vintage enthusiasts who appreciate its historical significance and playful yet refined design.

Casio CT6000 (12T Oct 84)

muzines.co.uk

A promising leap for Casio, the CT6000 offers musicians a MIDI-enabled, touch-sensitive keyboard with a range of improved sounds and features, including a pitch bend wheel and stereo chorus. While the keyboard's touch sensitivity could be more dynamic, and the rhythm section lacks world-class quality, the overall voicing and sound palette show significant advancements. Its varied selection of voices, from vibraphones to synth bells, is commendable, though the muffled percussion disappoints. Despite its limitations, the CT6000 is a well-equipped keyboard with unique offerings for its price range.

Casio CT6000 (EMM Nov 84)

muzines.co.uk

Casio's CT6000 keyboard is a bold step towards bridging the gap between home and professional use, offering MIDI compatibility and improved sonic qualities. Its touch-sensitivity and after-touch features are commendable, delivering standout sounds like Funky Clav and an impressive string ensemble. However, it isn't without flaws; some preset voices fall short, and dissonant overtones in higher chords could hinder recording sessions. While not a professional-grade instrument, it's an enticing option for home users exploring MIDI and digital music. At £695, its value for pro musicians is debatable, but it marks a significant move for Casio towards more serious equipment.

grainy strings

The sounds in this thing are great. The string sounds, specifically, are lush and grainy like a vintage Italian string machine. It also has a "stereo ensemble" effect to make things sound even more cinematic, plus the keyboard itself is pressure-sensitive! This, in my opinion is the best-sounding model in the "Casiotone" line.
