I am the host of this system, Ayre. There are two tulpas here with me, Coda and Segno. If you have talked to me at all, you have also most likely talked to Coda. She's pretty outgoing. Segno, on the other hand doesn't really talk online at all.
And yes, all these names are based on musical terms and symbols. I use them online just because I like the play on words. These are not our actual names.
