Comparing instrument sales numbers at all for influencing music is crap. It just takes one instrument to make a great recording that changes things. The famous 808 and 909 drum machines? Only 12,000 and 10,000 units ever made respectively. But I don't see song titles referencing the pocket operator :P The TB-303 was a commercial failure at acting as a bass guitar synthesizer. Then years later Phuture cranked that resonance knob and created acid house.
