whats wrong with hd-rec as is?
It's not that there is anything wrong with it - I already made the point that it's miles better than any other attempt at a DAW on the Amiga.
That being said, there are many restrictions that, after a couple of years, eventually pushed me away from using it as my DAW and ultimately the Amiga, although I believe many of these are hardware or OS related and not something Thilo could have done much about.
One example (and I think this is more a limitation of the Amiga than HD-Rec), having the ability to record several inputs at once.
hd-rec is also open now and can be improved by third party.
http://sourceforge.net/projects/hd-rec/
it is though written in amiblitz, so it isnt portable, but as long as you can run 68k on your sytem via emulation you are safe.
Yes, if I was a bit younger and had time to both learn amiblitz and spend on HD-Rec, it's something I'd be looking at.
Who knows, I may get around to it yet....
