May seem odd,but could come in handy.Seems alot of people here in the south (Florida) have become accustomed to playing music at slower speeds.
Variable speed control on motor?
Processor Mod.??
Need input!

do you mean the songs like tommy mckinnie uses?most ppl just uses software to slow them down and than burns them to a disc.i've used audacity you can slow them down,add bass or about anything you want to. http://audacity.sourceforge.net/
With oldschool CD players you could change a clock crystal, or inject a signal from a variable frequency source. I tried that with my old Philips CD-150 deck, and it worked (using fixed crystals). Elektor magazine published plans for a variable frequency source for pitch-controlling CD players; it looked useful, but by the time I came across the article the PC board and EPROM were no longer available.
These days, the smart thing would be to just use a laptop, or get a cheap DJ CD player. Or a DJ add-on for an iPod.
But, if you like messing around, get a cheap/old CD player, build some kind of variable frequency oscillator and substitute that for the crystal oscillator.
The only external mod I can think of would be a gizmo that changes the pitch without changing the tempo, like some karaoke processors have.
