for the KVR Developer Challenge I wrote a multitap delay where the delayed signal can be pitched. The source is available via google code (though currently without comments).
It includes a Juce wrapper for Dirac LE and an SSE implementation of the halfband filters found in the musicdsp.org archive. I also started a SoundTouch wrapper, but due to SoundTouch’s rather high (and varying) latency I didn’t implement it yet. Might come at a later point.
