Released in 2022, Casio’s 61-note Casiotone CT-S1 was immediately recognised as one of the best keyboards for beginners, and it remains so today. Rather than release a direct successor, then, Casio has launched a sister product, the 76-note CT-S1-76.
The obvious benefit here is that the greater number of keys gives you scope to play a wider repertoire of pieces, but that’s not the only advantage that the CT-S1-76 has over its smaller sibling. There’s also a more powerful dual 6.5W speaker system - the CT-S1 has a dual 2.5W setup - that includes Casio’s Horizontal Bass-Reflex System. This is said to improve the sound of the lower end frequencies.
