Can't sleep at the moment so may as well do some more programming, now the preset loader seems to work okay I'm making it so sounds can be saved on the fly and appear in the list straight away, should make creating new sounds quicker and more fluid.
Now updated to v0.1.6 - To save a preset click "New preset" at the
bottom left and type a name for it, press enter and it will be saved (to
~/.lv2/) and added to the list, if anyone has ideas on how to make the
interface more intuitive let me know, will have some documentation in
PDF format finished soon hopefully (have done the first few pages).
