As usual there is a lot of improvements and with a couple of them being a little bit leftfield.
The biggest so far is the sampler update which brings a lot of more functionality and possibilities to it. Just check out the video and as you can see it is possible to use effects modules directly in the sampler, with envelopes (amongst other things)!!!
There is supposed to come some more stuff that is not announced yet... suspect that it involves more Pixilang integration as there already is some ways to use Pixilang inside Sunvox for some cool things...
To test it on a PC/Mac/Linux go here (aso a list of all the new stuff):
