Hi does anyone know where i can find a guide for doing the pitch mods for the tr-707.I know this has been asked before on this forum but all info on this mod seems to have vanished.
I have established that it use 555 oscillators.I have know idea how one would go about making these .So if anyone has a detailed 'how to' it would be greatly appreciated.
