TOS


YouTube Uploaded by organfairy on Nov 29, 2011

"or Top Octave Synthesizer. In most electronic organs - and some synthesizers - from the 1970's the notes were generated by an integrated circuit that could make the top 12 notes from a single master frequency.
In this video I make a version of the TOS using only standard components. I will use it for something later...

The music is something I made in 2003 using Yamaha HE-8 and Technics SX-C600 organs, Roland JX-8P synthesizer and CR-1000 drum machine."

    Nice project! I'm going to build this. I see 68 and 72 for the B and Bb dividers on your main number crunch sheet, but its marked 64 and 68 on the first 2 swapsheets which confused me at first since the C also had 64. 2 notes using 64 and none using 72? The 2 circuits do seem to divide by 68 and 72. So I think its just the labeling. The mixing # and b in the note labels kinda threw me too. Even when I know you can C# or Bb.
