Hi, cool to see Crossfade Loop Synth and Augustus Loop being featured in the Beardyman video, I hope it brings lots of well deserved attention!
With Crossfade Loop Synth, I've noticed that aliasing can be quite noticeable at 44 and 48k, the most obvious being when playing the notes 1 half step below and above the original (B and C#). Playing the original pitch or its octaves do not produce aliasing. Other pitches do produce aliasing also, but the offending inharmonics are in a place less obvious than at B and C#.
Running at sampling rates above 48k progressively reduce the aliasing levels, with 192k being quite good. 96k may be detectable but usually acceptable.
Here's a quick sine wave demonstration video at 44k.

I used a sine wave for clarity of demonstration, but the aliasing is quite noticeable on other mellow sounds too, such as a vocal ooo.
I also tested Augustus Loop in the same way and confirmed it does not have the aliasing.
Thanks again!
