The line~ object generates a signal that interpolates linearly from its current value to a new destination value in a specified amount of time. It receives messages specifying a new value and the amount of time (in milliseconds) in which to get there.
Synthesizing a sinusoid in MSP is a fairly trivial matter, because the cycle~ object does most of the work for you. It produces a full-amplitude waveform at the requested frequency ƒ and with the requested phase offset φ.
When Max detects a bug or a problem in your patch, it posts an error message in the Max window, such as “sfplay~: cant find file <filename>”.
This example shows interference between two sine tones that have nearly the same frequency, causing a beating effect.
An oscillator is an electronic circuit that generates a cyclic (periodically repeating) signal.
The sigmund~ object is a third-party object for pitch tracking designed by Miller Puckette and Ted Apel, available on their page of downloadable Max objects
In some other examples (e.g., Linear fade-in/out of audio from a different course website) you can see how the line~ object interpolates sample-by-sample in a straight line from one value to another. You provide it with a pair of numbers––a destination value to go to, and an amount of time in which to get there––and it changes gradually (linearly) to that destination value in that amount of time.
This program demonstrates how objects in Presentation Mode can have a different location and appearance than they do in Patching Mode. Select the objects that you want to have appear in the presentation, and choose the Add To Presentation command from the Object menu. Then, to switch to Presentation Mode, click on the small easel icon at the bottom of the window (or type command-option-E). Now you see only the objects that will appear in the Presentation.
Max can interface with other applications via ReWire. Max can act as either a ReWire host or a ReWire client. Max can be a client to an open host application just by choosing "ad_rewire" as the MSP audio driver in the DSP Status window. Alternatively, you can use Max as the host (mixer) application by including the rewire~ object in your program.
The tempo-relative timing capabilities in Max can be used to synchronize MSP processing in time with a musical beat. In this example, timings of delays are specified in tempo-relative time units so that they remain rhythmically correct for any tempo.
