Hi,
The VCO's of the eml 101 let you sweep the waveform continuously from triangle to square to saw. This is done with a center tapped pot but these are very difficult to find.
Would it be possible to mimic this behaviour with a single or double ganged pot and some opamps? I would like to build a module that morphs 3 audiosignals with 1 knob in a similar way.
Thanks!
