tempo synced effects

[Owen Williams]

For post-1.12:

I got asked if Mixxx effects will be "bpm-locked," ie echos every 1/2 beat instead of arbitrary values. It should be possible to add a quantize button to each effect and pass them samples-per-beat information as well as a notification when the beat boundary occurs at the Xth frame of the current buffer. Effects can use this or ignore it (reverb doesn't care, for instance).

Is anyone willing to tackle this? I definitely think we need it, but as we get to the point where we're actually making builds I see no reason it should block the release.

(I think this is an important enough feature that people will jump up and down about it, at which point we have to reiterate that this is the first version of a rewrite of the effects engine and we plan to implement it, etc etc)

[Daniel Schürmann (daschuer)]

Is it required to have a dedicated control for it like a Super button or can we just use the deck quantize control.
We can do this anyway for deck effects only.

Or it is just a feature, a button parameter, of the some special effects?

I think we already heave the facility to pass deck properties to the Effect, so I think the later one will be the best.

You can do a lot of fancy things with this and it can be even more then one quantization button for a single effect.

A quantize multi band compressor would be cool. :-)
