Model 15, from Moog Music Inc., got a couple of updates over the weekend. The first update makes the Symbiotic Equations expansion pack free for everyone. Then another update was released to fix a bug in the ribbon controller introduced in the former update.
What's new in Model 15 v2.1.1:• Fixed ribbon main trigger not working anymore in previous update.
Changed in 2.1.0:
• The Symbiotic Equations Expansion Pack is now freely available through the App Store.
• Many small bug fixes and underlying engine improvements.
Here is a demo of Symbiotic Equations by Leon van Bokhorst.
