Yeah! Well I guess my point is DON'T PANIC- and don't just throw something out- a keyboard especially when it's just the keys not making contact. (I failed to mention I also found a couple of dried up crushed ladybugs inside under the keys) You might even pick something up cheap or a trash find that can still be made functional. After all, this unit is about 25 years old, and still going strong otherwise. Gee I wish I could just insert a picture or two here.
The progression of the Casio boards is interesting- this WK-1200 was the first I think to use this kind of platform, with a lot of voices and drum kit sounds, and it records 5 tracks but only stores one song at a time. By the time I bought the WK- 200 in '08, that was up to 5 songs of storage. The voices had changed in selection but still about the same quality.
I bought the WK-6600 5 or 6 years back because they had by then upped the quality of the sounds, and added the synth editing functions at a greater level. I see they still sell that same model, but they also now have a WK7600 that stores even more user edited sounds.
Anyway- they aren't a weighted board, but decent sounds and 76 keys for relatively low costs- so besides my Baldwin Hamilton Studio Upright, they are good boards to practice and get creative on.
