Looks neat indeed.
I tried the demo last night. It is cool how you don't have to compile anything to test stuff.
I got it to listen to my midi-keyboard and I managed to get some noise going. Haven't figured much out yet though.
I think it might be worth purchasing in order to make standalones and VSTs but I'm not crazy about the fact that you have to pay for the updates.
If it had been just paying for upgrades, it would be a different story. But updates? I don't know.
Still. Might be worth it
