I'm just in the process of uploading >2000 new wavetables for current users of the wavetable library that I've produced. All wavetables are compatibile with Icarus, Serum, Falcon and similar synths that use wavetables with 2048 samples per cycle. There are also 64x128 sample cycle versions for Waldorf Blofeld compatibility. I'm not aware of any single library anywhere that has >2000 entries!
However, I have dropped DUNE2 support. That is because DUNE3, which I am involved with testing, imports wavetables of the 2048 sample variety and can also export DUNE2 wt format for use in DUNE2. DUNE3 still also uses the wt format! The problem for me is that the file size is quite large and takes up more of my cloud space than is necessary. If this is a problem for you then let me know and I will convert them for you, however, you can also use the excellent Audioterm program for conversion yourself.
For Blofeld wav->syx conversion I recomend Waldorf Blofeld Wavetable Creator 1.00 from:

The wavetables being uploaded are all computed in Mathematica 11. I have developed simulations fro various FM synths, Casio CZ/VZ synths, analogue waveforms filtered with unusual (non-existent) filters, Karplus Strong type sounds as well as Karplus Strong cycles and other waveforms, e.g., analogue, fed in to the FM algorithms to simulate those FM synths that use AWM samples as inputs. I have also used some signal (mode) decomposition techniques that I currently use for my work to split samples in to different frequency bands since I miss the LP>BP>HP morph filter from DUNE1 so much!
There are now over 2500 wavetables in the library and if you haven't bought in to the free lifetime updates then you can do so here:
