The upcoming release of iOS 11 will be 64-Bit only, and Apple is now no longer accepting submissions for 32-bit applications to their App Store and is ending support for existing 32-bit iOS applications. In anticipation of this change with iOS 11 we recently updated QMix and SL Remote to be 64bit compatible.
In order to support 64bit iOS, the apps had to be built using a newer version of Apple's XCode, with an updated build target of iOS 8. As a result, the older iOS device ID mechanism that Qmix and SL Remote device permissions relied on was no longer available to be used. The newer device ID method required for 64bit support meant that in addition to Qmix and SL Remote, Universal Control would also have to be updated to use this device ID method. Consequently, an updated version of Universal Control must also be installed on the computer in order for Qmix and SL Remote to function correctly with the Classic StudioLive mixers (SL 24.4.2, SL 16.4.2 and SL 16.0.2 Firewire mixers).
The latest software versions are:
Qmix - 1.4.5848
SL Remote - 1.6.5848
Universal Control (VSL) - 188.8.131.52 (build 5848) on PC / 184.108.40.206(build 5848) on Mac
NOTE: Universal Control 220.127.116.11 for Mac is only supported on OSX 10.9 and later. If you are on an older version of OSX, Universal Control may not function correctly or may not even install, in which case you should consider updating to a newer OSX or using a different machine to run Universal Control.
Unfortunately, Apple does not allow multiple or older versions of iOS apps to be hosted on the iTunes App Store, and they are also no longer accepting any 32bit applications for submission, so there is no possibility to submit or post any older version of Qmix and SL Remote. There is essentially no way to revert to an older version of SL Remote or Qmix unless you have a backup of your iOS device that we can provide from Apple to do so, as Apple will only support the latest version on it's iOS platform.
