Re: [LAU] [Zynaddsubfx-user] zyn and the art of software maintenance

[...] Some more info. Yoshimi has now run continuously for about 20 hours. In that time I've been loading and saving entire parameter sets, editing patches and saving them, both with and without Rosegarden triggering notes. There hasn't been a single freeze! If there is no sound being produced, then patches load and save silently, although there are xruns showing in jack's message window. If Yoshimi is actually producing sound then there are usually clicks as the patches are changed, regardless of whether that particular channel is sounding. The amount of sound disturbance seems quite closely linked to the patch size/complexity. I deliberately overloaded it by getting Rosegarden to send a fairly fast pattern of notes to the Hyper Matrix patch. The processors maxed out sounding rather unpleasant for a second, then it was Rosegarden that just stopped dead complaining of no CPU room. Changed channel on Rosegarden (so as not to actually disturb Yoshimi's state) to play a less demanding patch and everything was fine. The Hyper Matrix channel was still live, as I could play notes from my keyboard via Rosegarden. I'm not seeing any xruns at all in response to MIDI input of Note On/Off, Master Volume, Pan, Modulation, Pitch Change. As far as I'm concerned, we've now reached a level of stability that makes live performance practical.
