Apply a Function to a Multichannel Signal The mc.apply~ object accepts a breakpoint function in the same format as line~ and applies it over the space of channels of a multi-channel signal. Each channel contains a sample of the function evenly divided in the X dimension. In addition, mc.apply~ can store up to 64 functions, edited by mc.function, which you can recall and continuously interpolate using a signal input. Cycling '74 MSP MC Function Index Specifies, either as a signal or float, the index of the stored function to output, where 0 represents the first function. A number with a fractional part will interpolate between functions, so 0.5 will be halfway between the first and second stored. Define Function in line~ Format A series of breakpoints that defines a function. The number of the function to replace is specified by the right inlet. Connect the second outlet of the function or mc.function objects to this inlet. Current Function Number Specifies the function that will be set by a message in the middle inlet. Connect the rightmost outlet of mc.function to this inlet. Function Applied to Channels A multi-channel signal containing a space of points representing the current function(s). Output channel count Sets the number of output channels in the multi-channel signal. The default value is 1. Function depends on inlet In left inlet: Sets function number to output (starting at 0); only has an effect when there is no signal connected to the left inlet.
In middle inlet: Set the initial Y value of the breakpoint function (at time 0). However until a list is received, the function won't be changed.
In right inlet: Sets the function number that will be modified by a subsequent list message of breakpoints received in the middle inlet. Function depends on inlet In left inlet: Sets function number to output (starting at 0); only has an effect when there is no signal connected to the left inlet. A float with a fractional part performs interpolation between two functions.
In middle inlet: Set the initial Y value of the breakpoint function (at time 0). However until a list is received, the function won't be changed.
In right inlet: Sets the function number that will be modified by a subsequent list message of breakpoints received in the middle inlet. Define a function In middle inlet: A list of breakpoints in line~ format (as output by the function object) defines a function for mc.apply~ to apply across a space of output channels. The list should consist of alternating value, time pairs. The function is applied such that the beginning (at 0) maps to the first output channel and the end maps to the last output channel. Function index Specifies the index of the stored function to output, where 0 represents the first function. A number with a fractional part will interpolate between functions, so 0.5 will be halfway between the first and second stored. By sending a ramp into the inlet inlet of mc.apply~ you can continuously morph between two functions. Number of Channels Sets the number of output channels in the multi-channel signal. When chans is set as a typed-in argument or when the audio is turned off, the change is reflected immediately. If chans is changed while the audio is on, the change is reflected the next time audio is restarted. Number of Functions Sets the number of stored functions. This attribute can only be set as a typed-in argument; it cannot be changed after the object is created. Ramp Time Sets the ramp time between changes in the output in milliseconds. Note that large ramp time values may cause unpredictable behavior when driving continuous interpolation between functions with a signal input.
