Reason was how I started developing the "music creation" bug. Nowadays it's surpassed the three reasons (funny) why most people move on to other - more professional - digital music workstations. It can record and edit audio. You can incorporate third party plug-ins on the rack - some major developers have jumped in. And now it even has midi out.
This way, and with the Rewire functionality, which means the ability to work side-by-side with another host program such as logic, in sync, and with the option to send audio to the host program. Great technology! Watching the video, one feels that a lot of experimentation can be done with this, since Reason's mainly a modular system.
Will check if there's crazy rack modules for it. The likes of "making noise" (a company that makes modules in euro rack format) would be interesting. I know they have U-He's effects, some new synthesizers and eqs, but would be much more interested in getting emulations of euro rack crazy stuff now that it's able to communicate with the hardware. Just add a midi to cv converter into the mix and I'd totally jump on it!
