Twilight? Pfft, Flandre Scarlet (Touhou) owns all over the vampires in that - that's right, your vampires were pwned by a little girl.
Now, 1AM rambling.
A seemingly irreplacable power transistor blew in my Casio CZ-1000 years ago, I bought a Yamaha DX-100 which was cool as it is effectively the same chip as the Sega Mega Drive and is patch compatible, despite how cool it was and the mini-keys (which I prefer) I always missed my Casio CZ. My DX-100 had failure recently, the board had cracked and the previous owner had reconnected the traces manually it appears, he did a good job but it seems to have cracked again and reconnecting the dead traces does nothing to help as it appears the ROM has become damaged.
I looked at controller keyboards in the hopes of them being cheap, all USB; no good to me, my gear is MIDI (MU-90R). They also cost >£70 for as many keys and controls as I wanted. I figured I might look for another DX-100, they cost hundreds now, might sell the parts from mine that still work.
I decided to look for another Casio, I've always bitched at enthusiasts for seeming not to like it. It paid off,
I just ordered this. It has broken volume controls, but if that is a problem I shall just stick the control in from my dead CZ-1000, I never threw it out in the hopes it could be fixed one day, it probably can't, but it can help this one, I wonder what it would be worth fully functioning. On second thoughts, scratch that, I plan to keep it and make sure it doesn't go the same way as the other one, though I suspect that was due to the crap 80's band that had it before me circuit bending it with a level of incompetence never before seen by humankind, seriously, masking tape with things like "need 330K here" stuck to a piece of wire bypassing some cut traces, I didn't know about this until it broke, I just thought the filter was broken and never used that much anyway.
