The cat is out of the bag. Propellerheads just announced their newest technology initiative. It's called 'Rack Extensions'  and you can find out all about them on Propellerheads web site. Rack Extensions are stand alone Reason devices that you can buy and integrate into your Reason Rack. Rack Extensions have knobs on the front, audio and CV plugs on the back, support undo, automation, and won't bring down your system if they crash. There will be a dedicated store and every extension comes with a demo period so you can try them out. Why did they do this? Are there any downsides? Do I REALLY like the idea, and what can we expect?
