MOTM

I have to admit I'm somewhat bewildered by this discussion.
Most resistors in MOTM modules have a tolerance of 5%.  For 
capacitors, the tolerance is 10% or higher.  The effect of 
inductance and capacitance generated by the lead wires inside IC 
chips is infinitesimal in comparison to the variations due to 
tolerance.

Every module is going to be slightly different.  In some cases there 
are trimmers to minimize these differences.  In other cases the 
difference does not matter.  Isn't this what we want as musicians?  
Does every Martin Guitar sound like every other?  Does every Les 
Paul sound the same?  It is that way for every musical instrument.

I remember a few years ago I bought a Yamaha Grand Piano.  I went to 
the warehouse and tried out a dozen different pianos.  There was one 
that most definitely sounded better than the others.  That was the 
one I bought.  They were all different, even though they appeared to 
be exactly the same.  

If you make a sound with two VCOs they will both have slightly 
different characteristics.  This is part of what makes them sound 
analog.  If they sounded the same you would say it sounded Digital.

My 2 cents.
