[sdiy] Roll Up & Go Piano

[Tim Heffield]

I found it in the clearance area of the toy department.  The sound is pretty
good considering it's a toy.  The 128 instruments are mapped to the General
Midi standard so it makes we wonder if there could be an unused midi output
lurking on the PCB somewhere.  The processor/audio generating IC is an epoxy
glob top device so interfacing to it would be a challenge.  The one in the
picture at the Amazon link looks a little different than the one I have.
Mine has a larger black enclosure and the sw/knob layout looks a little
different. Ever since I watched the Pink Floyd - Making of the DSM video I
thought it would be neat to make a sequencer with keyboard entry like their
old sequencer.  BTW the mylar ribbon cable coming from the keypad has 63
connections on it, if I counted correctly.  It looks like it maybe setup
like a 49 x 14 matrix.  It is polyphonic but I am not sure how many notes
you can play at once.

I checked our Target and couldn't find any.  Just curious ... where was it?

Electronics?
Toys?
Entrance clearance bins?
