Hey list,
I'm in a bit of dilemma here, my machine has only 1 GB of RAM and I'm
running linuxsampler, rakarrack and bristol with rosegarden sequencing all
of them together. As you can imagine, this does stretch my machine's
resources a fair bit, so I find myself needing to bounce-to-audio. Any
software out there that can do this relatively painlessly?
