Hi, Some of your ideas already reside in other projects, so perhaps consider contributing to them rather than starting yet another project. IMHO what we really need now in Linux community is a couple of really stable and versatile apps, rather than a huge number of unfinished projects.
If you are interested in live-control of various audio/midi processes, you may want to look into my RTMix. The latest version (that will be available for download very shortly -- squashing last batch of the nasty bugs :-) has midi and OSC implemented and can pose as a Midi router/server as well as network host/client, as well as do various algorhythmic things. What it does not have is sequencing capabilities (other than routing the sequenced data), although it could be easily expanded to accommodate for that functionality as well. I am sure there are other similar projects out there that address your needs in one way or the other. For RTMix go here: http://meowing.ccm.uc.edu/~ico/ Ico
