One thing I loved about UA unison plugins is being able to play through them while recording... unless I am missing something these new amp plugin's aren't able to do that... they only work as an input insert in my DAW, which means some latency, which means not good for getting a good performance. Some of the older amp plugins work great with unison, but not this one. I also wish Universal Audio still had call up tech support where I could easily sort out issues like this.
