Has this been done before? I wanted to experiment with a phaser with delta oscillating between two values. Is this an effect that already exists? Seems like it shouldn't be too hard to implement as a mod to an existing phaser (was going to test in software before I go doing surgery on an MXR Phase 90) for sinusoidal oscillation. Anyone played with this sound before?
Once I built Tube Screamer with some funky changes to the tone section that resulted in the phase oscillating "directions" when the tone knob was dialed just-so. Which is to say the characteristic "shark fin" shape would invert back and forth, but I could never figure out why it happened. It was either a faulty part or some dynamic capacitance in the germanium diodes I used. Sure made it sound like a bubbly phaser.
geo, I think I understand your question, but I have to tell ya, there already are two oscillators in there - one to shift the nodal frequencies, and one to time that shift, as controlled by the "Speed" knob. If you knew exactly where to look in order to hook up a 'scope, you'd find that the timing oscillator's output wafeform is triangular in shape, not sinusoidal or sawtoothed ("shark finned").
What is it that you wish to accomplish, please?
