Discussion about the Korg PolySix synthesizer

Some reason you don't want to read voltage and frequency off the screen of your scope?

One pin of the oscillator will look more sinusoidal.  The other will look more like a square wave, but they will vary from one chip to the next.  Sounds like it's oscillating, at least.  Probably the oscillator is fine.

 so i scoped the pins on
 the 8048. pin 2 gave me a pretty healthy looking hf  sine
 wave. pin 3 gave me a rather lumpier looking sine at about a
 thurd the amplitude. pin 20 gave me nothing at all.... no
 offset ... and  pin 40 gave me a healthy dc only offset.
 
 
  i could hazard a guess at
 the voltages but channels 1 and 2 on my scope dont agree at
 all and also dont agree with my dmm when measuring a AA
 battery... (throws hands up)
