It's not a circuit that you just send in a sine wave and get out all the harmonics though. It doubles the triangles using a full wave rectifier and multiplies by 3, 5 , 7 and 9 using wave folders. Then converts all of those to sines individually.mark verboshttps://www.blogger.com/profile/15906807282825175531noreply@blogger.comtag:blogger.com,1999:blog-5421148049293839355.post-30365039862827433802008-10-24T16:42:00.000-04:002008-10-24T16:42:00.000-04:00Mike, doesn't the 148 make its harmonics with wave...Mike, doesn't the 148 make its harmonics with wave-folding in the first place?Reedhttps://www.blogger.com/profile/11308063223339426472noreply@blogger.comtag:blogger.com,1999:blog-5421148049293839355.post-47834638009105654452008-10-24T09:12:00.000-04:002008-10-24T09:12:00.000-04:00Cloning this oscillator would definitely be an int...Cloning this oscillator would definitely be an interesting project, i'd like a couple of boards for sure!Quadhttps://www.blogger.com/profile/17634466071872660780noreply@blogger.comtag:blogger.com,1999:blog-5421148049293839355.post-58425404937221494522008-10-24T00:48:00.000-04:002008-10-24T00:48:00.000-04:00If you reissued the Music Easel I'd buy one. :-)If you reissued the Music Easel I'd buy one. :-)B+https://www.blogger.com/profile/15966774138172656802noreply@blogger.comtag:blogger.com,1999:blog-5421148049293839355.post-76994585271015502582008-10-23T23:34:00.000-04:002008-10-23T23:34:00.000-04:00Also, while we're playing 'what-if...'That 208 Tim...Also, while we're playing 'what-if...'<BR/><BR/>That 208 Timbre control? Okay, apply that to the sine fundamental coming out of a 148. Only it's a 148 that maybe goes beyond 10 harmonics, and maybe the harmonics can be detuned (because we don't want horrible Hammond-style ET or simple whole-integer harmonics-just a few cents either way would make a big difference).<BR/><BR/>Now, wouldn't that be lovely? Programmable harmonics with adjustable tunings and levels, the coolness of the Timbre folder, either/or, and then a CV could sweep between the two.wavingpalmshttps://www.blogger.com/profile/04065024875871294182noreply@blogger.comtag:blogger.com,1999:blog-5421148049293839355.post-70570327542433595912008-10-23T23:14:00.000-04:002008-10-23T23:14:00.000-04:00I'll say it again: wonderful service you're provid...I'll say it again: wonderful service you're providing here. I've been fascinated with his way of doing things since first reading an interview with Buchla reprinted in the copy of Tom Darter's 'Art of Electronic Music' in my high school library, around 1991...<BR/><BR/>Recently, I was one of the lucky ones that scored a copy of the Easel manual in that eBay auction, and that's gone a long way towards clearing things up... your blog is doing much more than making up the difference.<BR/><BR/>Again, thanks- wonderful work you're doing here.wavingpalmshttps://www.blogger.com/profile/04065024875871294182noreply@blogger.com
