Any aliasing you get from playing it faster is already going to be applied before it hits those filters. If you wanted to get rid of it you'd have to stick the sample playback parts with the filters in a subpatch and in increase the samplerate using [block~]. I think the artifacts you're hearing are coming from the grains comb-filtering each other.
I'm finding that there was aliasing in general not just from the speed increase. Perhaps I am using the incorrect term for the effect as its more like bit rate reduction. I find that the filter chain at the end works well for the results I want. This is a technique I use to improve the quality of a DAC built in circuit. Plus the cheby~ can create some crazy sounds if the variables are modified.
You might be right about the comb-filtering of the grains though. I'm going to experiment with it a little more. I love this patch though, reminds me of spinning records.
