Tutorial Re: Schematics Archive

Hi Gene:

I'm sorry to hear that your tutorial wasn't a rewarding experience. I did 
find the internal description of the OTA very useful. I did get a bit bogged 
down around the bottom of page two (where you suggested a new type of OTA) 
since this seemed to be directed towards the EEs on the list (ie, out of my 
league). I guess with tutorials and FAQs, we users all to often don't bother 
to think of the amount of work the author has put in to them.

When I suggested this as being a good use of introductory DIY space I was 
thinking specifically of your OTA tutorial, the (extremely helpful) capacitor 
FAQ, and the "what do I need to get started?" FAQ that is (was?) at the 
Synthtech site. I'm sure there are others that I can't remember at the moment.

I still think that a programmed tutorial geared specifically to the needs of 
the audio and synth building novice is a worthwhile project, but I can 
understand that it might not be worth it to the author if their work was not 
given adequate appreciation. However, I would be very interested in your 
insights into opamps, VCOs, and expo converters, etc.

BTW, I'm really enjoying the thread on sound and perception, I now see why 
Martin was asking for recent books on psychoacoustics a few weeks ago.
