MilkyTracker Bug Reports / milky interface somethimes becomming unresponsive with jack
« on: March 06, 2010, 01:53:45 »
I've just compiled mt 0.90.85 on an ubuntu 9.10 system with self-compiled jack 1.9.5, and finally...jack works!!
it's working really well, I've just tested at 88200 khz rate, and milky seems to be able to handle that, no aliasing on high-pitched notes that _did_ alias badly at 48000 with the cheapest resampler! strange that sdl/alsa drivers don't offer >48000 in the gui while it's working with jack, maybe that should be fixed?
well...the problem: sometimes with jack in rt mode (happened at 48khz, so I doubt it's related to an unsupported sample rate), when I click around the system and reenter the mt window, the player becomes unresponsive to input! gui updates well, sound is gap/xrun-free, with cpu around max (it's a slow pc), but keyboard and mouse input won't respond for long times, like it takes half a minute after I clicked something (also the wm close button) for mt to respond, keyboard also lags like that. working is impossible when it happens (other than listening to the song & watching the gui).
I'd really like to get that fixed, because it's annoying. anyone got ideas on how to solve this prob?
btw, how does milky do its mixing & passing data to jack? jack works with 32bit floats, I hope the mixing isn't 16bit integer & then converting to floats (but I fear so...)
