Today we habe these huge monitors but still have to struggle with tiny, tiny blurred text in some interfaces. I strongly agree with your point about my eyes not getting younger … So I think it was a great idea to make all logic windows resizable – I love it.
I still like many of the NI libraries, not because of their design but because of their sounds and functionalities. So I have to deal with the interfaces.
The sampler I feel most comfortable with surely is EXS/Logic Sampler. It’s loading fast and reliable, with low cpu usage, and all functions and modifications of sound are easily accessible.
If I had a wish to all those great interface designers out there: make it BIG and make it simple. Make form follow function.
