Yeah, it's called Soundmesh and your description is quite correct (including spelling). :-) As far as the MIDI stuff is concerned, RTMix is capable of that by either relaying MIDI data to a client or a list of clients. Alternately, it can also convert MIDI to OSC, and/or to custom events and relay it that way. Both apps can be found on my site (http://meowing.ccm.uc.edu/~ico/) Ico P.S. apologies if this is a dupe, been having some problems with webmail access
