Morphing Terrarium Plugin?

Anyone know of any plug ins that can achieve a similar effect to the morphing terrarium? Like a plugin that can shifts between waves gradually and seamlessly?

You mean a wavetable synthesizer?

Serum is a very good wavetable synth. You can even upload/draw your own waves.

Yep I second Serum, it's absolutely amazing for that though for some reason I don't use it often (seem to update it more than I use it!).

Zebra also allows morphing between wave forms, though is a bit more limited as that's not the main feature of the synth and does all sorts of lovely stuff (especially Zebra HZ, mmm yummy analogue filters!)
