After discussing the issue of parameter automation in Stylus RMX 1.7 with customers and amongst ourselves, two points are clear:
1) Some users are relying upon the automation of parameters other than the 74 officially automatable parameters in RMX. We didn't intend for those other parameters to be automatable, and in most hosts they are not, but there is a loophole that permits them to be automated on some hosts. In order to improve the compatibility of automation across versions of RMX, it was necessary to close that loophole in RMX 1.7. However, that causes hardship for some of our customers who have come to rely upon automation of these "unofficial" parameters.
2) Our customers like the way automation works in Omnisphere and that is a good model for how an instrument with a large number of parameters like RMX should do automation. In fact, it has always been our intention to eventually incorporate the Omnisphere style of handling parameter automation into RMX.
After considering these two points, we have decided to help customers who have come to rely upon this unintended feature of 1.5 which is not available in 1.7 by offering a free 1.8 upgrade to RMX which will include Omnisphere-like parameter automation. This means you will be able to automate almost any parameter, you'll be able to easily manage large numbers of automatable parameters, you can save and load automation templates, the parameters will be named, your songs which use automation will be upwards compatible with new versions of RMX, and it will be available in all hosts which support parameter automation. In other words, the support for parameter automation in RMX 1.8 will be far superior to what was available in RMX 1.5.
We will be announcing the date for this free upgrade shortly, but we wanted to inform you of our decision as soon as possible. In the meantime, if you are using RMX 1.7, please note that it is not necessary to use parameter automation to control parameters from your host or control surface. RMX 1.7 has a comprehensive MIDI learn system you can use instead.
