+modprobe snd-virmidi
+have had problems with it not being recognised - rebuild seemed to fix it
+
+
+6 controllers
+each note switches in 6 new visuals which are at the same strengths
+as the previous bunch
+
+is it necessary to represent them seperately?
+
+maybe take them all in, but initially modulate one picture on the strength of the strongest
+
+maybe each object is a plugin and the 6 controllers affect 6 parameters of it
+ie speed, matting type, colour tweak
+
+object that plays when a note is received can be called a track, a sample, a bank, a layer?
+
+object remembers playback head/ heads
+
+initial footage set for each track: program change?
+(does this leave any room for creative input) or set via gui?
+
+creative input - alter layers live via AVS compatible system which also allows local MIDI control,
+scripting, manipulating layers etc
+
+probably pretty tricky to create a .ape loader - difficulty in recreating the windows GUI
+
+probably a lot easier to think about a way of making a modular editor that can be manipulated live
+nice to think about making scripted layers - using nseel or other
+
+initially - divide screen into grid - play notes with fade
