Hi Adam,
Not to be argumentative, but what I'm talking about did not happen on Fairlight hardware and could not possibly happen given its architecture. Aliasing actually cannot be an artifact of sample playback through a DAC. They used R2R ladder DACs to produce a zero-order hold ("stair-stepped") output, and then they had to filter out the stepping artifacts, which are all above the Nyquist limit. (Aliasing produces artifacts below that limit.) Their tracking filters removed those high-frequency artifacts (many of which are supersonic), but even those would have been the same, relative to the note pitch from note to note. What I hear in QasarBeach are artifacts that are lower in frequency and vary in intensity (and relative pitch) from note to note. The fact that they vary from note to note strongly implicates the ASRC as the culprit, which only makes sense given the limitations of a software implementation.
My question was about whether you had considered doing something innovative with the ASRC to make a better emulation of the hardware. The hardware units do not do ASRC as part of sample playback. All software emulations must. So this is a weak link in software emulations of the Fairlight.

Dan
