I was thinking of a wavetable module.

It would work by defining a series of curves, analogous to the Generator series of curves (i.e. things like saw, pulse, hand-drawn), doing an analysis on each of the waves in the series, taking a morphing speed, and from that series and speed generating a summed curve.

It could also have a couple of looping options (forward, backward, pingpong ...) as well as an ADSR.

It would not be easy to automate during a track, but because of its precalculated nature it would be fairly efficient during playback.

If this was done, i'd like to see something in function like a graintable, that way you could, say, create a wave with a filter sweep applied, but instead of calculating the filter in realtime, you simply shift the portion of the wavetable and the looped section/grain, which is not only a way of handling a different sound processing that's not already in sunvox, but can also be used on low power devices in some instances to get more effects with flexibility. There's an example of how it can be used sonically outside of this area both in Ensoniq keyboards and in Reason's Granulator synth (I think that's what it's called, it's been a while since I ever looked at that software). It's a unique sound and would work as expected from the original request as well as offer a new sonic soundscape option at low power to sunvox, imo. I think possibly it would have to work a little like the SpectraVoice, where it renders the table 'silently in the background' so if you change the base waveform, it won't actually take affect for a small period of time...or it could simply have a 'render table' button (which should never be allowed to be used as a pattern effect, just as 'EDIT' on a sampler isn't allowed).

It's not very CPU efficient as all sound generators are running at the same time, but there are ways to set up structures in SunVox to approximate wavetables and morph between them.

Here is a post about one such method, to which I'm about to add a link to a YT video that demonstrates it: viewtopic.php?f=20&t=4497&p=15757&hilit ... tor#p15757

I'm aware of the workaround to approximate wavetables, but I'd rather see an actual wavetable module that pulls it all together.

It'd work better for polyphony as well.
