Well the paid, and paid dearly for at the time, companies have been given ten years to even get the basics right
They have dropped the ball like noone's business. Only in the very last few years, has any of the native stuff handled auto-input "zero" latency monitoring anything close to right. In fact *THEY WERENT EVEN AWARE IT MIGHT BE IMPORTANT *
VST and DX have locked inputs, allowing ONE and ONLY ONE send stream to acess those inputs
Good job they were paid for, if thats how it is, I want my money back
On the other hand, open source software ( not quite the same thing as free, though it can be free), leads to a meeting of the minds. We see how strong Linux is, I say we give them a few more years to work out the implications of open source
Sad to say, that for free, the lowest latency at the lowest CPU cost has been realized for quite sometime. Take a trip thru linux with an RME soundcard and see how that works, "hammerfall mixer" murders any windows or mac hammerfall setup. Ardour's beta is a a shining light of efficiency and stability.
And just so the facts are up, reaper isnt free, its in beta
Unlike most companies who ask the customer to pay for the beta test ( though they sell it as final), reaper is getting its ducks in a row through real world user input, and is succeeding in so many areas
