Childish whining on Analogue Heaven?!?  The hell you say! ;)

>design a synth for less than $50 worth of parts from the DigiKey catalog!!!!
>(assume some old f*cked organ keyboard available, and power supply)

It needs a keyboard??  Anyway, what is the definition of "synth" ??  Is the
competition to build the best synth for $49.99 or less, or is it to build
the cheapest thing that is a synth??

Does it have to be able to accurately sound notes that it is told to play??
If so, you would be dealing with all of the tempco/exponential converter
problems in building VCO's that are a perennial topic on this list.

If not, you could get one of those cheap music generator chips they put in
answering machines and such (hey, it has its own sequencer :)  Add a
battery and an output stage and you have a device that satisfies one
definition of a synth for only a few bucks.  Then again, I don't know if
these are in the Digikey catalog.
