I like Zebra. In fact I like it a lot! But I've always been slightly frustrated by the way it handles sync. A lot of synths require 2 oscillators synced together to make these sounds, whereas Zebra has a dedicated sync function which gives you.... well, one flavour of sync. I decided to see if I could program some more flavours using Zeb's wavetables, and here are the results -

The saw and triangle syncs span 3 octaves, the square only 2 as there's a limit of 33 points that can be added to a geomorph wave.
If someone's already done this then I apologise for the redundant post, otherwise.... Happy Sync-ing!
