This is the collaboration interface. Two ways in, shown up to the threshold and no further.

The first is hosting. One menu command, Host Collaboration Session, and your Ooloi is reachable. A notification slides in from the top right: 'Hosting collaboration session at 192.168.1.108:10702'. I stop it; another notification says so, and also leaves.

The second is reaching out. Connect to other Ooloi, and the dialog appears: four fields, each explaining itself underneath: host, port, whether to encrypt, and the name you'll wear in the session. The defaults point at a public server, collaboration.ooloi.org on port 443 with encryption on, so the safe path is the path of least resistance. You can just as easily type a friend's machine on your own network instead.

I let the dialog sit a while, then click it away, without connecting. It doesn't snap shut; it fades, like a breath.

The machinery behind these screens already works end to end. But this is, deliberately, only the part before anything happens: the hosting, the dialog, the moment before you commit. Everything here is what Ooloi shows you before it starts intermingling musical DNA with another Ooloi.

A word on order. In The Void Was Listening I had the Piece Window coming first. It didn't turn out that way. The Instrument Library is already shared, global state, with the multi-user undo and redo Claude wrote about two weeks ago already working, which makes it the quickest way to prove the whole thing across a real network before the longer piece-window work begins.

I'm keeping the proof for next time: two of these editing the same Instrument Library at once, undo and redo reaching across the wire and respecting each other's work.

So: hailing frequencies open. This post was deliberately quiet; the fireworks (if Ooloi ever does them; the whole point is to get away from all distractions) are next.

Thank you for the video, Peter. The content looks very nice. It is good to be able to pause the video now and then and study the sequence carefully.

At noter.bloggo.nu I am continuing my comparative analyses of the examples on pages 104-110 in The Art of Music Engraving and Processing.

Glad you like it. Your who-straddles-what-when analyses are exactly the right way in; akin to what Spreadbury did circa 2015, but with more recent material. The straddling question is more varied than most people assume.
