Harmonaizer=?

[R@bbiT]

Can someone tell me how the harmonaizer work? And it would be great if you could name some of harmonaizer pedals, i Would like to see a schematic of this device.

Thank you

check mark hammer's site, if I remember well there was an articol about an analog harmonizer.

I have a Boss stereo harmonizer pedal.  The concept is brilliant: two independent voices, with individual volume and selectable intervals.  A 12-position rotary switch lets you choose what key you're playing in.  It works fine (again, in concept) for major and minor keys, but if you're playing harmonic minor scales, you have to play the higher voice, because if you play the lower, the tracking makes as if you're playing a standard minor scale.

This pedal is pretty good for octaves, and I think fourths and fifths are OK too, but the tracking is waaaaaaaaaay too slow for other intervals (like thirds and sixths).  It has a nice detuning feature, though, which to me is what saves the pedal (I only use it for this).  If you set one or both voices on the center position (i.e., no interval) it detunes the signal slightly, making it sound like a chorus effect.  Really nice.

me too. that's the whole reason I bought the thing!

i would like to try having a harmonizer with (or modding a haromnizer) "harmonized" effects loop, so you can like run a chorus through it.

hmm perhaps the "ultimate" chorus would be multiple harmonizers each with a chorus line... but darn that would be alot of work. and its the same to work stompboxes anyway......

I wonder if anyone has tried that "ultimate" chorus... it would get expensive really fast, but it might produce some really cool sounds. I'm personally a fan of clean octave-ups or 2 octaves up (used somwehat sparingly)

It would be pretty easy to rig up using a wave editor or software such as Sonar/Cubase/Audacity. You might even be able to get it to work in realtime... but of course you'd be going through a PC. Just something to try before buying a few shifters.

thats true ! I havn't thought about it.

perhaps just recording a clean guitar part, then copying the same track onto different tracks and then adding effects to them. sure beats trying it out on a perfboard.... just to hear how its like !

The Boss Dimension C/D does more or less what Leandro described in the analog domain.  Look at the schem for the Dim C and you'll see that it employs two BBDs with individual clocks driven by opposite phase versions of the same LFO.  So when one BBD starts to decrease its delay time, the other is increasing.   The result is that the two BBDs essentially trade off with respect to which one takes care of the sharp and which takes care of the flat, such that there is always something sharper and flatter than the input signal.  This results in much less "wobble" than you find in a conventional single-BBD chorus, and decreases listener fatigue dramatically.  You can leave this thing on for ages and not mind.  Although the harmonizer doesn't do *exactly* the same thing, slight stable deviations in pitch produce a similar sound.
