I think we can all agree that plugins are generally much more powerful than what you get in hardware and the sounds are amazing.
That said, I think the one thing that people don’t think about is “playability”.
For example, you can have the greatest hammond organ plugin there is, but if you’re not using a waterfall keyboard and decent feeling drawbars (preferably multiple sets) as opposed to those toy sliders on most controllers, then it just isn’t quite right.
Similarly, if you’re playing a Minimoog, the positioning (and size) of those knobs makes a huge difference. That big filter cutoff knob on a Minimoog makes all the difference for performance as opposed to having 9 tiny little knobs in a row.
Even the Kronos (and the original Oasys, which was my original introduction) gives you amazing hands-on control that the virtual world just doesn’t quite capture.
I’m certainly not giving up my virtual environment for touring, schlepping “real” instruments is just not worth the hassle for me. But I miss that playability.
