Once again another fractional delay (hybrid)

[Tepeix]

Once you go into the fractional delay problem it's hard to stop digging more and more..
Or maybe, it's me that have an obsession ...?

I find this little design, an hybrid from simple linear and recursive content..

What seams maybe an advantage, very low attenuation just where the phase distort more,
but this is not linear at all for bass and maybe i hear some artifact when the feedback is high..
Also, this one could make a delay from 0 to 1 sample.
