[LAD] hard realtime performance synth

Hi, Where to start? I have a Dell 7000 laptop and I'm wondering if it can be a music synthesizer(something like a Minimoog). If not, why not? I know there are much more powerful machines out but that's beside the point. If the goal is a dedicated performance grade synth(as in it sounds good and d

Hi, Thanks for the response. Some thoughts 1. Bristol synth was one the first synths I tried. I had installed Ubuntu(Karma I think. BTW: Ubuntu is based off Debian and that packaging system didn't seem to save me from breaking things) and then used various "apt" commands suggested on the Ubuntu

Hey! Bristol synths are very good, but I have problems with them. They do run on my system, but I am not able to use most of them reliably, since if you play fast or play a long succession of notes, the synth simply uses up too many resources and eventually gets kicked out of jack. So my dream to u

Which is interesting. I did not notice on my ASUS laptop any significant difference between rt-kernel and a normal one. It was there - a bit less dropouts, but the change was not significant, meaning that my non RT kernel mode works almost as good. On Wed, Jan 27, 2010 at 9:47 AM, David Olofson w

Well this is sort of the direction I was hoping to go anyway. I've heard of Xenomai but haven't looked at it. The RTAI system was a package on Debian(Ubuntu) and so I bit. I was disappointed to find out that instead of installing a workable system, the package only installed the source code. I bui

Ok, this may a partial fair point, but I don't think its impossible that with a machine with 100+ MB of RAM that one could screw off virtual memory(paging) especially since I'm not really after having a soundfont library available so much as having something that calculates a sample at a time. The
