OT Re: [sdiy] Bob Moog - Mini pulse widths

[kheck73 at aol.com]

I remember it was about glitches in the waveform from the core of the 
oscillators somehow related to limitations of the power supply.

I've listened to many, many recordings using the Minimoog and lusted 
for one since childhood. I thought that other synths allow detuning of 
oscillators, sound Moogish, so why spring for a Mini? Well, I recently 
took the plunge and got one with the old oscillators. I have to 
acknowledge that there is something magical here. I think part of it 
has to do with the pulse waveforms and how the higher harmonic contents 
phase against each other when the oscillators beat. Other synths I've 
played don't have as much of this going on even with the filter wide 
open. I don't know if it's the glitch waveform thing or whatever, but 
it is real and I can hear it plain as day. Also, I now know that many 
recordings I've heard do not fully capture the breadth of the sound.

Does anyone remember..was it Kevin or who that did a bit of research a 
while back and found that part of the charm of the mini is that it has 
somewhat sporratic pulse widths. And apparently at an intermittency 
that gives the sonically interesting dynamic timbre the pulse waves. 
They had analyzed 
why it did that too and it's been to long. I should 
have that information posted on my site....what did I do with the old 
emails..I just looked and can't find them...Harry? Tom? Anyone 
remember? -Bob
