New upload: Buchla 291 filter + Schaeffer design
2004-01-04 by Jeffrey Pontius
Hi all, I've uploaded a Schaeffer front panel design for the rendition of the Buchla 291 filter that Scott Stites and I have been working on for the past 6 months. It is in a new folder called Buchla Type [I find it much easier to search for panel designs based on the module than on the designer] with the file name Buchla291_mixoptions.fpd. You can view a photo of the Schaeffer panel, along with Scott's custom panel design, descriptions of the filter and our added features, sound samples from Scott's breadboarded version, and a schematic of the 'core' of the filter, based on Mark Verbos' version of the 291, on Scott's excellent website: http://mypeoplepc.com/members/scottnoanh/slsdiy/id11.html. Schematics of our added features are not yet posted. I would like to publicly thank Scott (the electronics expert in this project - certainly not me) for all of his work on this filter. It is really a neat filter. It is a 3U motm style panel, I've tried to keep the cost reduced and still, hopefully, instructive. Note that the pot holes are smaller than those required for Spectrol or Bournes pots. The socket holes are for Switchcraft 112, and the switch holes are for NKK. Jeff
