PC / Linux / OSX. The video shows of all the functions but it is possible to use it in endless ways inside of SunVox as you can connect anything in any combinations etc.
It is another module that can have unforeseen creative possibilities as it can be combined with any other module/s in unlimited ways. Lately every update comes with one or two new modules that takes SunVox into an experimenters heaven.
Remember that you do not have to use SunVox for sequencing notes. What I am trying to say is that so many people gets put off by the tracker sequencing or by the look of the interface (myself love it) but you can use it in so many other ways, for example building crazy synthesizers and effect modules that you can play with live on the Theremin Pad.
Or use microphone input and route whatever modules to affect the signal like the Pitch shifter module... Actually it is pretty endless what you can do and I feel a little bit bad for people that do not take the time or have the energy to dig a little bit deeper into SunVox as there is so much creativity and pleasure to be had using it.
