[PD] framesynced midi recorder/player

[wolfgang schwarzenbrunner]

hi list...

here is the question:
since quiet a time i am working on project which simply generates bw lines 
in dv resolution and higher. those lines are midi controlled from a logic 
environment. now - as the stuff finally looks the way i want, i am looking 
for a way to capture it. to get it on tape in dv res is an easy task to do 
but the most parts of it only work out in higher resolutions (hd). if i 
want to capture in resolutions like 1080 x 720 or even 1920 x 1080 i need 
to use pix_write -- and this -- off course -- is not working in realtime.
i thought of a little workaround which could work out:
in a first run i run the stuff without any video capturing. only the midi 
data should be captured to a kind of timeline which is rasterized to 25 
fps. in a second run the captured midi data is played back by a player 
which goes 1 frame forward each time pix write has finished rendering 1 
frame. i think this would be a possibility for a nice off-line rendering 
system. somehow... did anyone ever tried to build a system like this? does 
anybody have a tip or a glue how to do?
i think a thing like that might be useful for a lot of users anyway.
