There are 12 beta bounces in Compositor 4 Extension 1 packet, which cut on masters in WAVE 22.05 kHz 24-bit format for subsequent pressing on vinyl or writing to a tape. Beta Bounces, as the name implies, are not a final series of Compositor 4 extensions. The HB – High Bounces and AB – Alpha Bounces will be released also. The device profiles database is updated with Beta Bounces under BB prefix. There are 43 radio loops in the set, which add device profiles of different purposes to Compositor 4. To check if they suit the ether you can load the presets from four banks, which delivered in Beta Bounces set, and press the Ether button after calling the preset. Radio loops create an ether, and Compositor 4 builds them to the point, when they are recognizable as devices in the ether to which this ether is attributed, but is not the original broadcast from which the loop is recorded. Radio loops may be used not only for broadcast design in film industry, the semantics of radio loops language ideally suits for chemical composition. For example, radio loops may be viewed as the link chains created in the places, where these sounds connect. The simultaneously played sounds depict the valence of link and the transitions between the sounds are the number of these links. For example, three step melody, where the first step starts on the three notes chord may depict the three valence link in the beginning and two one valence links going afterwards. Radio loops are suitable for the cyclic compounds, such as octane links. It brings Compositor 4 in a row with devices for compositing materials. In such case, master cuts suitable for ether mixtures, which are subsequently fixed and become concrete materials.
