Re: Wave shapes transition triggered with midi, plus envelop

A little bit unusual question, related to certain practical topic. Morphing too, but for different purpose.
Is there a way to load "on-the-fly" new shapes to wavetable oscillator? I noticed, that standard wavetable creator - produces a large glitch in sound output. I see, that the wavetable creator - makes 128 variations of an input shape, and i guess that this is related to antialiasing and smoothing the wave. Does it have to be 128 parts in mem for sine wave?
What I'd like to do - is to achieve non-poly (standard stream) wavetable oscillator, that would emulate multiple sine units. While using multiple sine oscillators takes a lot CPU, one such wavetable oscillator could just have a shape, that corresponds to a predefined (static) mixtures of let say - 10-16 sine waves. Sine sub-units manipulations could be done then in the green when needed (frequencies, phases), and single oscillator would receive a multisine-pack definition, without a glitch.
Then instead of making 200 oscillators I would have only 20 of them.
Is this doable and how? This one?
