Qtractor 0.5.0更新日志：
MIDI controller learn/catch-up sees the way in: MIDI controller changes are now only effective after catching-up with their respective program ">parameters, avoiding abrupt jumps and keeping a safe and continuous behavior. Track/Height menu is now
featured, gi
ving access to Increase, Decrease or Reset the
current track height. All changes to audio gain and panning on tracks and buses are now applied following a piece-wise linear ramp, reducing the old nasty clicks, pops or zipper artifacts that might be awfully audible on some situations,
most specially on automation. All zooming in/out is now relative to either the viewport center or current mouse cursor position if found la
ying inside. TYOQA! the underground sources have emerged:... after years in the making, track automation, or dynamic curves as some like to call, is finally a reality, tricky but real ;) Audio clip anti-glitch/ramp-smoothing effect is now slightly independent of current buffer-size period (mitigating bug #3338113 effect). Once buried under the Edit menu, Clip menu has been finally promoted to top main menu. Debugging stacktrace now applies to all working threads. Fixed muted loop playback on audio clips ending coincidentally with the loop-turn/end point. Old/deprecated JACK port latency support added to audio recording latency compensation. Audio clip merge/
export lock-ups now untangled (fixes bug #3308998). LV2 extension headers update. Fixed
configure of newer LV2 host implementation stack (LILV) when older (SLV2) is not present.
