Is it possible to modulate where you are in the Wavetable with an LFO or envelope like you can in Waldorf Largo?
-
Not yet. It's already in our wish list.
-
Taken into account that you can setup 4 oscillators and balance between them with the 2D envelope, what is the point of cycling through the wavetable? On the other side, I would think that a quantisize function for the 2D envelope would be great to recreate the PPG Wavetable stepping. I wonder if this is possible already.

The point is in the number of waves we can load into the internal DSP memory. We currently can load 16 waves of 128 samples each. These 16 tables corresponds to 1 table per WaveTable osc, 4 WaveTable osc max per slot (program), 4 slots max in a multi, which yields to the number 16. We have to experiment others waves management scheme so as to be able to load or access a greater number of waves to implement the cycling.

That's not possible today, but that's a good idea. It's noted into the wish list.

the point is to do the very thing you ask for at the end of your post, to recreate classic PPG wavetable sounds. hard quantized stepping between the waveforms is a characteristic part of the PPG sound...

Isn't that what I said? However, not all stepping leads to the PPG grunge!

One thing to consider is that they PPG Wave and Prophet VS used two very different approaches to wavetable synthesis. The PPG had tables of waveforms where there was a gradual change in harmonic content from one waveform to the next, which meant that stepping through a table resulted in a smooth'ish sweeping sound. The Prophets VS, on the other hand, had no such arrangement of the waveforms. Instead (adjacent) waveforms were radically different, and this was much of the point as the 2D vector envelope mixed 4 of these waveforms to make smooth transitions between them.
Thus, sweeping the VS wavetable in a PPG fashion will not yield anything like the PPG sound, but rather a jumble of very different spectra. Of course, that in itself could make some cool sounds, just nothing like a PPG.
For the very good reasons mentioned by philwick, i.e. the memory capacity of the TS-203 DSPs, I doubt it will be implemented. Instead, given a quantizer module (on my Origin wishlist...), one could make a stepped sweep with any of the Origin filters and get close to PPG-land that way - well, not really but at least one would get gradual stepped changes in harmonic content. It would also use very little memory and be computationally cheap.

yes, you are right, good point. I forgot about that. they are set in a very specific order, although the waveforms towards the end were pretty drastically different, it was mainly the first 2/3 of the table that were arranged in a manner in which to get smoother sweeps...
