Re: [linux-audio-dev] Guidelines for developing a music editor

(I'll answer this as best I can, feel free to correct me where I'm wrong.) This seems like a very hard problem. Since your sequencer is "just that: a sequencer", you'll also need plugin hosts and/or standalone synths too, which understand either MIDI tuning or OSC. (One OSC-driven plugin host, Om, has been mentioned already). The majority of standalone synths and plugins will probably never be able to play anything other than a conventional tuning, so that's a problem, unless you're happy to write a few of your own. (By the way, re VST, some existing synths and/or plugin hosts can host VST, but again most VSTs expect MIDI or MIDI-style commands and implicitly assume a conventional tuning.) I'd love to see a general-purpose OSC sequencer, and I'm sure others would too, so keep me informed if you're thinking of taking this approach, and maybe I can help out in some way.
