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. Sound that can be directly loaded into Zebra2 later. And should you eventually decide to upgrade to Zebra2, you will already know everything there is to know about the oscillators – which is quite an advantage.
Zebralette has two LFOs (one per voice, one global), a multi-stage envelope and three on-board effects (chorus, EQ, delay). Not forgetting Zebra2's famous dual spectral effects, which include several squelchy filter algorithms.
