I was estimating that version 0.1 would be in release form shortly after June, but it looks like it could still need some more work, and I’ve spent my time mostly on other projects.
Biggest issue is with life cycle, the plugin interface provided by Lightroom is very limited, so the actual MIDI input is done is separate process. The process is started when plugin starts, but there is no proper way of telling when Lightroom exists.
So, it might take a week or two longer 🙂
