Automatic PDC - Automatic PDC should now work for all normal use-cases (please report issues). We still need to fix these cases: Multi-out plugins, Multiple generators feeding a single Mixer track, each with different latencies and the wet/dry mix knob on FX slots. These should be resolved in coming betas.
Automatic PDC now works with Generators.
APDC applies to inter-track routing and side-chains.
Manual and Auto-PDC can now co-exist. Manual PDC is applied as an offset to Auto PDC.
Manual PDC - Negative values - delay the selected track, positive values - delay all other tracks.
There's a new audio input delay control on the INPUT menu to fix latency issues with individual audio inputs.
PDC icons now light orange when a track reports latency, not when it's delayed (as before). This will help you to quickly identify PDC inducing plugins.
Direct Wave - A Zone's loop type will now apply to all selected Zones.
Fruity Reverb - Is now a 64 Bit FL plugin.
GUI - The 'Song/Pat' switch is a placeholder. The main purpose at the moment is to show you are using the FL Studio Beta. We are converting all tool panels to 1-unit high. This will allow for a more streamlined tool-bar and more flexible arrangements. More later ...
Help - FL now uses the online version of the help file. You can download an offline version here (although FL 12.9 won't open this by default).
Mixer - Increased to 125 Mixer tracks. More will be added later.
Patcher - Reduced memory usage.
Playlist - Improved visibility of Clip borders in Solid view mode.
Time Signature Support - Playlist, Piano roll, Project Settings and Time Markers. Right-click Time-markers and select 'Time signature'. Shift+Alt+T to set time-signatures over a selected time-range. Use the on Pattern Clip Menu 'Use current time signature' to set a time-signature based on Playlist position.
