Very nice. I wish I had the talent, training, and playing ability to create this type of music. Sadly, it's too late in my life to start now.
You touched on a number of things in your post worthy of separate discussions and I'm hoping someone will pick one to 'flesh out' for further discussion.
Question....do you feel that using a controller/VSTi robs you of some of the expressiveness achievable in a dedicated (self-contained) keyboard? Does the computer and/or audio interface diminish things like touch response (latency, however small or seemingly imperceptible), natural attack, response, release, etc.? Would love to hear your feelings on the subject.
