Playmodes is an audiovisual tool for the sincronic manipulation of live audiovisual flows. It uses as a raw material the audiovisual stream coming from any live av source (cameras/microphones, AV mixers, internet) and it deconstructs this flow following some rules which are defined by the different play modes.

The tool works similar to an audio live-sampler / looper, with the difference that it manipulates not just audio but AV as a unique information. Once stored the buffer, it is possible to manipulate this content with a series of AV effects, linked to a BPM:

RANDOM.
Random movement of the playhead to stocastic positions of the movie. Thie frequency of the movement can be linked to a bpm, and quantized to the beat, so the jumps are only made to significant parts of a rhythm.

MULTIX
N copies of the AV flow are superposed and delayed by n miliseconds (or bpm divisor), resulting in an effect with a very special plasticity.

REVERSE
The AV signal is reversed. Using some audio envelope following techniques, this effect can hear when a word or a phrase is ended, and immediately reverse it. 

RECLOOP
AV overdubbing. Once a loop length is selected, the recording starts in a loop mode, permanently overwritting (in a non destructive mode) the stored content. Some features of this mode can also be triggered by audio events, and recording can be activated when the audio rises a definde treshold.

DELAY
The AV signal is delayd by n milisconds, or any bpm divisor.

L8P
AV loop recorder. 8 different loops can be stored, manipulated and played polyphonically.

REPEAT
A beat repeat effect, linked to a bpm. When activated, the last n bpm divisor is repeated.

SLITSCAN
A slitscan effect, as used by the great filmaker Zbigniew Ridcinski.

 Playmodes also implements Live AV Timestretching and Pitchsifting, so all of this effects can be applyed using this as modifiers. At the moment it consists in a C++ coded application (which is already downloadable) for the video effects, and a reaktor enseble which does the same effects in audio. Both applications communicate whith each other via the OSC protocol.Here you can see the control GUI:
