Here are some photos of an oscillator design that I have been working on recently.
I came up with a simple design for an oscillator using an op amp, a capacitor, and four resistors.
The object of this project is to get some good oscillators working to use in a synth.
The schematic for the oscillator is included in the photos.
If you have any questions about the project, don't hesitate to ask!

you will get a square wave out of that end. It would be a good idea to use a buffer (unity gain amplifier) to amplify that signal first (so that the filter itself doesn't interfere with the frequency and characteristics of the oscillator).

alternatively,
If you want to use a "shark fin" wave, you'll have to put a second (preferably unity gain) amplifier on the positive node of the capacitor. then the output of that second op amp will be where you would connect your filtering circuit.
