I've been using Sound Forge since Sonic Foundry's version 4.5. I upgraded to Sound Forge Pro 7, then to Pro 11. In other words, I've been a user for many years.
I downloaded Sound Forge Pro 12 recently and tried using it on some of my routine work. I found the changes Magix made to the toolbar icons in v.12 were a hindrance to my productivity. That's the primary reason I am sticking with 11 until an operating system change or other act of God or Microsoft make it impossible not to upgrade. It was totally unnecessary to replace the familiar icons.
I also have customized my toolbars in Sound Forge Pro 11. Before I threw in the towel in frustration, I could not find any method for importing my settings to the new release. If there is one, that would help, but not enough to persuade me to switch.
Thanks for reading my rant.
