a bit ago i started a javascript osc environment [1] for fun. a copy of touchosc, but in the browser and you can edit your controls live.
i didn't have any intentions to share it, but this seems to be an appropriate venue. it's not nearly as cool as anything else in the thread :). pretty proof of concept, but maybe will get some ideas going. the relevance is that it's easy to execute arbitrary code [2] to control any program that supports osc/midi.
Would be amazing to reuse your syntax inside a VST plugin, to write arpeggiators, drum patterns or other similar things.
Thanks for sharing!
