except of course that fades up / down from BLACK rather than fading the alpha in/out !
I think that sequencing is best done via "end actions" ala ableton live. I have made a FF plugin that does this via OSC but it is kind of clunky (it would be far neater if done natively in resolume) it would be nice if you could have the option of crossfading to the next clip (a single global crossfade duration setting would probably be adequate) this would have to work between clips in the same layer for it to have any point.
I don't see the point in a more traditional step sequencer internally in resolume as you can already do this easily using an external midi sequencing app, the point for me is to be able to build chains (playlists) of clips. The end action system in Live is almost perfect as it allows for randomness as well as strictly ordered playlists and clips can be made to loop X number of times before the end action is triggered.
