Lately I am testing and exploring by coupling basic synth with MG3.
Zebralette is very powerful even if it’s only 1 oscillator (the full Zebra2 has many more) but it’s a wave synth and you can play with it (as with Zebra) by drawing your harmonic or waves curves with your mouse.
you can find it here : Zebralette: Easy spectral synth | u-he
But if you are willing to try it’s next incarnation you can try Zebralette 3 Beta
