[A6] A6 sine osc

[Kim Johnsson]

Hi!

I'm not particularly knowledgeable in analog circuitry, and I don't have 
that much experience with real analog synths, so that may explain my 
question...

I understand that basically analog synths don't produce "mathematically 
perfect" waveforms, and that's just the way it is. Different synths' 
"versions" of each waveform may also differ, and I guess this would be 
true for different manufacturers as well as different units of the same 
synth model.

Well, I just noticed that the sine wave of my A6 doesn't really sound 
like a pure sine wave (and I can lo-pass filter it, and the sound 
changes), so I recorded it in Sonar at a low frequency, and it looks 
like this: http://www.kolumbus.fi/kim.johnsson/temp/a6sine.jpg

So, is this the standard A6 version of a sine wave, or is it just mine 
that's a bit bent? And out of curiosity, if I would want an analog synth 
for the sole purpose of creating a nice sine wave (with it's 
oscillator), which synth should I get? Which synth is The Ultimate Sine 
Machine?

Oh, if I make the A6 LP filter self-oscillate, I get a *really* nice 
sine wave...

Just a bit curious,
