slide~ Slide filters an input signal logarithmically between changes in signal value. Slide filters an input signal logarithmically between changes in signal value. The formula is y(n) = y(n-1) + ((x(n) - y(n-1))/slide). It's particularly useful for envelope following and lowpass filtering.	from the library : MSP Format : External Environment : msp commercial Max 4.x http://www.cycling74.com
