ReplyDeletenone of them with the weirdo oscillators. would these be late production 100s then?
ReplyDeleteLate CBS Dual VCOs - production approx 1969/1970.
ReplyDeletethere are several minor changes to the 158 VCOs over the 5 or so years (1966-1971ish) of SFMTC/BA and CBS production... will outline them on my site one day.
The late model 158's with VC waveform aren't so terrible. To my unseasoned ears the saws are a bit more pleasant on the earlier SF Tape Music Center ones, but in a world of limited filtering I'll take the tradeoff.
ReplyDeleteyes, but there are no "graphic oscillators." when did don abandon this concept?
ReplyDeletewhat is a Graphic Oscillator exactly?
ReplyDeleteperhaps you mean the 132 Waveform Synthesizer. If so as far as I was told by Don he made 1 for the proto system but it never went into production... Buchla often develops modules that are never produced or produced in small quantities...sometimes even mock up panels were made for press releases but the module was never developed.
sorry, that was me posting above. all i mean by graphic oscillator is the sequencer clocked at audio rates. does the 132 operate on the same premise as the harmonic generator just with out the attenuating knobs, or is it a different concept all together. i've read that he said that type of implementation of additive synthesis is not particularly effective. the delay units, frequency detector, and brainwave module are in that vain of made but not produced so to speak.
ReplyDelete"the delay units, frequency detector, and brainwave module are in that vain of made but not produced so to speak."
ReplyDeletesort of.. they were developed for particular pieces/performances (232/277/272).. or development was started and never completed in the case of the 288
