i will try more things out, there is source for that and autohotkey so i hope to learn that way. i also got python's pywin32 library to do some of my mouse moves, is nice.
idw, i did hear about a modualr midi controller, where you can plug in whatever sorta things you need, but i unfortunately dont know what to search for.. maybe "modular midi controller" and keep looking that way!
modular thing is cool but expensive indeed.
the gap on the m-audio x-session might be a little annoying, but the only suitably usb controller i've seen so far with 4 faders. thanks for the links.
i think i go with an used korg on ebay and some day build my own midi controller from scratch.
can't wait to test along..
