Metro 7.4 is now available from the downloads page and new demos are also available. This update is currently free to existing users.
I will update this topic with the change log, which is huge.
The biggest things are Music Code, the new polyrhythm drum editor, multi-track support for the lead generator and Rhythm Explorer. The infinite player, (the Metro IPS server which is not available yet, customers please contact me if you are interested). Recording directly from a VST track and much more.
When the infinite player is live there will be an infinity sign in place of the number of tracks (37). Please email me if you would like to see what happens and I will go live. It is quite possible, with the use of sections, to make an online album with songs that repeat but yet are never the same.
