I just found the article here....

the E&MM harmony generator. I have not yet been able to pick through the article (I need the right head for that)...but I havent seen much info on this stuff around here. Are there any other projects/articles out there? has oneone built this one?
oops, :icon_redface:
If you do a search on E&MM Haromony Generator, or just "Harmonizer", there will be at least one post on it. If you don't find it, let me know, because I have a hard copy of it, and can tell you the post number. Anyway....there was a guy on that thread who had actually built the thing, and said it worked per the schematic. I guess each 3rd, 5th, octave, etc., is a separate feature, and you can only dial in one at a time. Â I looked around on Mouser, and different places, and the chips are still available for it. I had a parts list made out and everything, but I got involved in some other circuit, and didn't follow through with it. I think it would be a lot of fun, and a challenge to build too!
it recommends 0.4w resistors?
Its only for a mono synth.
I actually did find _some_ other info...

is that the thread you were talking about? The search was filled with people talking about octavers...not really what i was looing for. The search for E&MM yeilded no build reports :(. Anyway...The whole 3rd -5th up seems pretty cool...
maybe this winter, if I have some extra time :-D.
I guess that's another thread (mine) although the basis comes from one of the files on Mark Hammers page as well. A very advisable project if you want to learn a lot about harmonizing and the difficulties that come along with it. If you intend to have great results I'd strongly disencourage you to go for that project. I'ts difficult, contains errors, and is out of tune and very glitchy in the end. ;)

How about this one?
Check out RickL's posts.
I spent the evening playing with the midi control of the digitech wammy pedal. I had a sequencer plugged in. Very cool to play one note on my bass and have crazy 2 octave arpeggios playing!...
doh, found that one, but somehow skipped over it. I think becuase of the second post lol.
Good info...I'll absorb it all soon :-D.
Dirk - Thanks for the advice. "out of tune and glitchy" lol
that 2nd post "oopsed", coz I fell over the BBD-"harmonizer", and couldn`t completely delete it... :icon_redface:
The 33038.0 post is the one I was referring to that SolderBoy referenced. It had Rick Ls explaination of the circuit on there, and a great disertation on harmony generation by Mark Hammer.
