RE: Synths (software vs hardware, speed)

[Nick Copeland <nickycopeland@xxxxxxxxxxx>]

Have you tried starting Qsynth as root rather than as "user"? The failure to set the scheduling params indicates you don't have sufficient permissions and logging in as, or 'su'ing root would at least overcome that issue. Not sure why the program exits though as I did not write it - perhaps it will not start the midi process unless it has rescheduled? Pure conjecture, I carry on regardless although it could be argued that.....
 
And yes, linux software is rather terse. Its not really written for users. I have submitted a couple of times on how it could be made easier however most linux users seem to equite 'easier' to 'dumbing down', which I disagree with.
 
Nick.
