Movie attributes

The object has a large number of attributes that you can use either to modify the object's behavior or to get information about the video it's playing. To set an attribute, you send a message consisting of the name of the attribute followed by the value(s) you want that attribute to have. For example, to set the 'vol' attribute (the volume of the video) to 0.5, you send the message vol 0.5 to

Using timepoints for interactive sequencing

The timepoint object sends out a bang when the transport reaches a specified time position. This can be useful for causing something to happen—or for starting an entire process—at a particular instant during the transport's progress. A timepoint might, for example, even trigger a new time position value to be sent to the transport object itself, thus causing the transport to leap to a different time.

Polyphony requires multiple objects

Any given MSP patch cord represents a single channel of audio. If you want to generate or process multiple sounds or channels, you need to treat each sound or channel separately. For example, each sfplay~ object can have multiple loaded sound cues so that it's ready to play any one of several files, but it can only play one sound file at any given instant. And if it's a stereo file you need to treat each channel separately for mixing, processing, etc. This patch demonstrates that.
