Soft-synth interface design

[Andy Tarpinian]

Ok the topic is software synthesizer interfaces. Joost and I are  
asking you all to please list your thoughts on this much debated  
topic. Please reply to the shelter and let us know. Any thoughts you  
have will be valuable to us, here are just a few questions to get you  
started:

Which software synth interfaces do you like and why?
Which hardware synth interfaces do you like and why?
What elements from hardware synth interfaces belong in the software  
world?
What elements can you dream up that could only exist in software?
Do you appreciate shinny pretty graphics? Or do you prefer basic and  
clean?
Do you like soft synths that look like old hardware? Or like they are  
a holographic interface from 2483? Or in between?

These questions are just some basic ones, the sky's the limit, any  
and all thoughts you have will be appreciated.

Thank you,
-Andy
