Interestingly, here's what Kirk says about his decision to close Kirk Hunter Studios:

Quote
Many have speculated about my decision to step back. There’s no single reason, but primarily, at 65, I feel it’s time to pursue more creative and enjoyable ventures, which are already gaining traction. Additionally, with the rise of AI and evolving technology, I believe the business model for sample library development no longer aligns with my goals.

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
