I'm into building synthesizers from scratch. I've recently built a low frequency oscillator as part of an instrument which works well, based on a TL074 quad op amp. However, it uses a heck of a lot of components and is rather 'clunky' as it requires a great deal of switching to allow 4 different waveforms (rising saw, falling saw, triangle and square).
I've been trying to improve this circuit by cutting down the components required so it can fit on a smaller piece of stripboard.
I found this image on google, with no context or explanation. Caption says it's just 'an idea'.
I have several 4069 chips and would like to try it. Before I commit it to perfboard, can anyone tell me if this schematic will actually work? And if so, what will the P-P amplitude of the waveforms be?
