I am a proud father of little girl who was born in february 2008. I just found her a kids toy synthesizer at a local flea market for 5 euros. Now it seems that I am the one who enjoys playing it more. It has these ridiculous cheap unrealistic sounds like piano, guitar, banjo (my favorite), flute etc. There´s also buttons for funny little sounds like frog, dog, bird... But hey, that´s not all. There is also a set of pre-programmed rhythms like rock, slow rock, waltz, tango etc. which you can slow down or speed up. The best of these pre-set rhythms is called 16 bit which is a killer low fidelity-trash-dirrrttty electro beat! (loop sample here) Drive it through distortion effect at 110% volume and you got a nice punky disco beat.
I´ll probably use this marvellous little toy somehow in my future projects, unless it breaks down before that. My daughter´s playing style is more punk than mine, meaning she likes to beat it real hard.
