M-Audio has released a series of MIDI-keyboards with a proprietary protocol called HyperControl (http://www.m-audio.com/index.php?do=media.maudiotv&PID=dbf4e90a4c68b457d70d7afec74c3746). Some of the biggest DAW:s (Cubase, Reason, Ableton Live, Logic and Pro Tools) already have support for HyperControl but unfortunately M-Audio has chosen to not release any public SDK so anyone can implement such support for their applications so it has to be done by M-Audio themselves and it seems they currently do not have any plans to do so for Renoise, but I found this thread http://forums.m-audi…-s-HyperControl where they seems to be willing to accept requests for other implementations. So, how about to post requests for a Renoise implementation?
I’ve just posted a request myself but the forum is moderated so it will probably take a while before it will be showing up.
