a lot, esp from early 6ixties would prolly use individual oscs for each 
key.. at the time, RTL single flip flops were pretty state of the art and 
cost loads [late 60's] imagine trying to implement things like /239 for 
proper TOS dividers? easier to make nice osc for each key if its 
polyphonic..
