My first keyboard was a Casiotone 501, not a synth but it did have a barcode reader so you could program in songs and it would play them for you and you could follow the notes and learn the songs.
I then bought a Korg Poly 800 (Series I) when I was 16 which was great fun to play with and lasted for about 10 years when the magical smoke was released after a relative (who shall remain nameless) lost the plug pack and plugged the wrong supply into it, fried everything on the board...
About 2004 I bought a second hand Korg Triton LE which has some really amazing sounds and pads but I have never gotten around to fully using it, my daughter now uses it to learn piano on
