Hey, these are great! Thanks for putting them up. In the "up" file, your frequency shifter sounds a bit like a ring modulator when it gets really high, but otherwise, it's not like any effect I've heard before. If it was kept to smaller ranges, it could almost pass as varispeeded tape, minus the speed changes. I'd be curious to hear what it sounds like on acoustic sounds (voice, piano, guitar, etc). The phasing effect is cool - it sounds more like flanging than what you'd get with a conventional phaser, but not as metallic as flanging and without the delay. There's almost a "barberbole", Shepard tone thing going on in these samples. Very cool.
