Bests & Worsts Reviews from Amazon

At age 65, I am presently a retired Professor Emeritus of Music, and have just purchased this Casio SA-77 keyboard, not for piano practice, but for working out the harmonic (and even contrapuntal) details of new compositions that I seem to be writing more frequently now that I am retired. This keyboard will definitely make it easier for me to do so. The keys are big enough for me, and it has a helpful array of sounds and good volume control. I really look forward to utilizing it, rather than always working out all of the details in my inner ear. I can still do that, but the keyboard will potentially add a higher level of interest to my works. I still use the computer to write, but now I can take this keyboard along with me anywhere I go. No MIDI input, earplugs or adapter are provided, no problems there. I just place 6 AA batteries in the keyboard and earphones in my ears. I love this keyboard! Absolutely!
