cresc-decresc crescendo / decescendo generator Transition between a start velocity and an end velocity within a certain time. When the start velocity is bigger than the end velocity, a decrescendo will be obtained. If the end velocity is bigger than the start velocity, it will result in a crescendo. A bang is sent out the right outlet when the dynamic transition is over.	from the library : Real Time Composition Library Format : Abstraction Environment : max / msp freeware Max 3.x / 4.x http://www.essl.at/software.html
