It is a free upgrade (as usual) and to many people the most interesting news is probably 64-bit compatibility. It also features new MIDI controlling possibilities (including pattern edits via MIDI CC) and a beautiful new skin with spacier layout and crispier pixels. (There are several other minor improvements and bug fixes but we refer you to the Change Log chapter in the User Guide for the complete list.)
One important addition to Microtonic 3.1 is a utility called Authenticator that will help you register and unlock the Sonic Charge products you own by simply entering the logon name and password you have chosen for this site. An internet connection is required to do this, but in case you do not have a connection you can still register from within the plug-in with your name, email and registration key. Authenticator exists to help you, not to be a copy protection system.
(At the moment, Microtonic is the only product supported by Authenticator but we are going to introduce this technology to the rest of our product line as soon as possible.)
With this release we are also consolidating our downloadable patch packages into a single installer. As a bonus, the installer contains a brand new package called Patternarium Stellar Beats Volume 1. It consists of the 100 most popular beats yet on our ever ongoing genetic experiment of Patternarium.
Speaking of Patternarium, we have just launched generation 16 with another 1000 beats. However, there is an important distinction between this and older generations. We felt that it was time to diversify the gene pool a bit so we made it not only from the most liked patterns of generation 15, but from all the previous generations! In other words, the beats that are spinning in Patternarium right now are the offspring from the best beats of all time.
