[A6] Some waveform observations

[Robert Skerjanc]

Hello all,

I made some strange observations, possibly some of you have an answer to 
that:

1. the basic waveforms of the VCOs look very strange, when you see them 
on an oscilloscope. "Saw" is not a saw wave at all, also the other 
shapes are not mathematically geometrical, but they sound as they 
should. Is this a specialité of the A6?

2. The VCOs have linear and expon. type of FM. Normally the linear type 
is intended for the modulation to stay in tune (negtive slopes detune 
the carrier in same amount as positive slopes), like the DX7. However 
linear FM on A6 stays not in tune. Possibly the reason are the weird 
waveforms mentioned above?
