I've pushed Project Drainpipe onto gitorious:
https://gitorious.org/drainpipe

Of all the people in the world, y'all are the only folks who I imagine might be remotely interested.

Project Drainpipe (aka Neuralyte Tracker) is a tracker (powered by IBXM) with a RESTful interface. There is a crude HTML/ECMAScript interface. Screenshot to follow. Basic pattern editing exists. Persistent storage as json (to/from CouchBase) is implemented in the vanilla code. No instrument or sample editing interface has been coded (but the API exists). The code is beta.

I'd appreciate feedback - if you can get it running, or bug reports.

Basic build and run instructions are available.

Roadmap: Have a look at the README in gitorious.

Final word

PS: I begin a version of this project three years ago at Sundown. I can't make Sundown so this is my way to celebrate in absentia.
