Mark Hammer![]() | Re: Octaver Effects The E&MM Harmony Generator project at my site (http://hammer.ampage.org ; scroll down a few pages) does precisely this. This is a project by Paul Williams that appeared in Electronics and MusicMaker quite a few years back. It uses a 4046 chip as a tracking oscillator to generate a note well above the actual pitch of the note you play (like most octave dividers, this is a mono device). That note, in turn is divided down by a counter chip to yield a variety of intervals, including fifths. There is a PCB layout included in the PDF files. If you want to build the project, though, you will need to: a) digitally tidy up the PCB layout with a paint program of some type, b) rescale it so that its spacing matches that of the chips, and c) flip it mirror image if you wish to use press-and-peel or some other similar method of transfer-based etch resist. I've never made it but apparently it works fine from reports. |
