building an ascii to midi AU plug

    Sep 24 2007 | 12:13 pm
    so ive been playing a bit with mainstage, and more specifically i think im becoming hooked to some of the logic plugs(the epiano is especially nice)
    rax has been bought(again) and one if the new features is supposed to be ascii control of midi functions
    but im starting to think that i may just stay with maintage for live usage
    and as far as i know, mainstage doesnt do anything like that, and its unlikely that itll be an added feature, since its more 'pro' than that
    what i would like to do is to create an (AU) plugin (to work in mainstage/rax) that will convert key messages into midi note messages, with some sort of dropdown menu interface to make it more openly usable, to control with a rehoused 10key usb numpad 'foot controller'
    making that in max shouldnt be too difficult
    however, i have no idea how to go about making something like that into a plugin, or if it would even work (does 'key' work outside of max, in a plugin, or if the plugin/app is minimized), or if its possible to do so with just max (do i need pluggo for this?)
    i did a forum search, and a quick google search, but only really found the examples in the pluggo product page, which are audio processing plugs
    so i guess theres 2 questions:
    is it possible to make something like that at all?(using max)
    how does one go about building the plug specific architecture?
