Specifically, from a conceptual point of view - I would like to see a
TransitionManager class, with a addTransition method, which implements a
Transition Interface, so I can do something like this (in sudo code):
include "transitions.h"
TransitionManager xfaderMgr = new TransitionManager ( xfaderControl )
TransitionManager channel1Volume = new TransitionManager (
channel1VolumeControl )
TransitionManager channel2Volume = new TransitionManager (
channel2VolumeControl )
Transition 64beatfade = new FadeTransition( *64, BEAT *);
Transition 12barfade = new FadeTransition( *12, BAR *);
Transition 16secondfade = new FadeTransition( 16, SECONDS* *);
...
So I can do stuff like this:
crossfaderMgr.startTransition( 64beatfade );
channel2Volume.startTransition( 12barfade );
channel1Volume.startTransition( 16secondfade, FadeDirection.REVERSE );
In words, I'm transitioning the xfader over 64 beats, bringing channel 1
volume in over 12 bars (bars is just a short cut for beats/4) and over 16
seconds fading out the volume of channel 1.
...
Every transition manager is listening to an onBeat event, so if BEAT or BAR
transition type is set, it will call Transition.nextFrame or
Transition.prevFrame on the beat.
As you can hopefully see, something like this would provide an incredibly
flexible framework for creating complex transitions, which can then be
implemented as a clever autodj class
just my 2cents...
cheers
Keith
The transitionManager will call a method each bar
