Zebralette has two LFOs (one per voice, one global), a multi-stage envelope and three on-board effects (chorus, EQ, delay).
Zebralette is just one of Zebra2's oscillators packed into a simple, easy-to-learn framework – but you have everything you need to make some pretty amazing sounds.
Its a very interesting synth for sound design.
