[sdiy] More on the AN299 VCO

Okay, for some reason, I'm only able to post once a day. I've been trying to send this for about 24 hours now. So here's try #umpteenth.

To Samppa - 'You don't specify any figures for the drift.' - I didn't think to take measurements when I did it. The drift is pretty slow, I'd guess about 1Hz every 2-3 minutes after warming up. On the other hand, that's ludicrously fast for musical purposes! And it never stops.

I just remembered a few things:

The extra components on my schematic vs. the National schematic come from attempts to stabilize the thing. Most came from suggestions that were made the previous occasions this topic came up on Synth-DIY. I highly recommend the SDIY Searchable Archive: http://search.retrosynth.com/synth-diy/index.html

The saw standardizer is from  ‘Musical Applications of Microprocessors’ by Hal Chamberlin.

k, I think that’s it…
