Hi all. I'm very much a newbie, and I've been making music on Ubuntu for a couple months now, even though I don't know as much about Linux as I probably should. My usual setup is to have up to 8 or 9 amSynths, sequenced in Seq24, and maybe Creox for special effects, running on Jack. Up until recently I couldn't get amSynth to work in real time so I just ran it not in real time and put up with the clicks and static.
Finally I got tired of this, reinstalled Ubuntu and got Jack and amSynth working together in real time (it took me a day and a half, but I managed it!) Now the sound quality is beautiful... if I only open 4 or 5 instances of amSynth. But if I open more than that, my laptop makes a horrible noise and freezes, and the only way I can shut it off is to take the battery out. I spent some time trying to figure out why this happens and finally twigged that the Jack panel shows its CPU usage. When I play just one amSynth the CPU usage is 41%, and for 5 amSynths it's a massive 82%, which explains why my computer freezes. So it seems my computer just isn't fast enough to do what I want it to do :-( So my questions is, is there anything I can do to fix this, short of buying a faster computer? Would it help if I got a better soundcard? I don't mind spending some money to fix this if I have to, though obviously I'd rather get the computer I already have to work if possible. My laptop is an IBM Thinkpad T40, 1.50 GHz, and the soundcard is a Radeon Mobility 7500. Any suggestions gratefully appreciated, Katie. -- Ubuntu-Studio-users mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
